Section 1 - IntroductionA successful reciprocating gas compression package blends precision component selection, fabrication,sales, and service. Ariel works with the packager to lead the industry in performance as well asreputation. This standard is a minimum requirement for packaging quality. Ariel encourages packagersto exceed this standard with the finest quality packages. The packager must conform to this standardeven if it exceeds end user specifications.Packager refers to any party incorporating an Ariel product in the manufacture and/or assembly of acompression system. The packager must ensure that the selected compressor is compatible with theapplication and properly integrated into the gas compression system.NOTE: This edition of the Packager Standards is based on current design, build, and prac-tices for reciprocating compressor packages. These standards may not apply to previouslybuilt equipment and are subject to change without notice. Depending on the source, thesestandards may not be controlled copies. Visit www.arielcorp.com or contact Ariel for latestrevisions.

Partial Scope ProjectsA partial scope project is when any entity other than the packager completes any part of “package” orcompression system assembly.Regardless of the scope offered, the packager retains the obligation to “package”, install, andcommission the compressor in accordance with this standard and good industry practice. At the bidphase, the packager must clearly define the scope of supply, identify areas of concern, and inform thepurchaser of partial scope requirements.Partial scope situations:1. The user purchases a complete compressor system or “packaged” compressor unit and chooses to

use their own construction group to install it. In this case, the packager must guide the user based onpackage characteristics. At minimum, guidance should include:• Studies required for foundation design• Anchor bolt layout and elevations for off skid equipment and piping• Anchor bolt, spherical washer, and nut requirements• Pre-grout alignment requirements• Grouting best practices• Direct involvement in commissioning

2. The user purchases an incomplete compression system without key components such as inter-connecting piping and vessels, instrumentation, drivers, control systems, or coolers. At minimum,packager guidance should include:• Applicable Ariel Packager Standards requirements• Correct sizing• Applicable code requirements• Anchor bolt layout and elevations for off skid equipment and piping• Anchor bolt, spherical washer, and nut requirements• Pre-grout alignment requirements• Grouting best practices• Oversight and verification of compliance to Ariel Packager Standards• Direct involvement in commissioning

REV: 5/13 Page 2-1 of 2

Section 2 - ApplicationsPackager Responsibilities1. Utilize the most current version of the Ariel Performance Program for compressor selection, per-

formance evaluation, pricing, and access to other application information and data.2. Develop complete familiarity with all compressor frame and cylinder design limitations, such as:

speed, power requirements, rod load, maximum allowable working pressure, discharge tem-perature, capacity control arrangements, balance, and lubrication.

3. Properly price each compressor with all options to meet the design service. For questions, contactAriel.

4. When evaluating existing equipment, obtain equipment serial numbers. Check with Ariel for designratings of older equipment as they may differ from current ratings.

5. Understand and properly evaluate customer specifications and take necessary exceptions and pre-cautions. Since operating conditions may change, make every effort to identify:a. Design point conditions and any possible alternate conditions.

• Valve selection is based on operating conditions provided with the order. Multiple/alternate con-ditions can affect valve application. Note startup conditions (or average first year operating con-ditions) with order for best valve selection.

• Suction valve unloader application is based on all operating conditions provided with the order.Operating conditions and available on-site actuation pressure determine suction valve unloaderdesign and actuation pressure. The packager must provide available site actuation pressureinformation to Ariel at time of order.

• Valve performance is a function of valve lift. Applications with a wide range of operating con-ditions may require low lift valves. Low lift valves may increase compressor power require-ments. Using low lift valves to extend valve life for site conditions not normally requiring themmay negatively affect valve efficiency and compressor performance. Contact Ariel for specificsbefore requesting low lift valves.

b. The gas analysis to properly identify and address any special components.c. Site conditions, including ambient temperature, elevation, dust, humidity, rainfall, wind velocity,

etc., and the impact of these conditions on package design.d. The duty cycle of compressor operation and its impact on compressor and package component

selection and design.6. For any special application, see the Ariel Application Manual. For questions or details, contact the

Ariel Application Engineering Department. Special applications include:a. Suction pressures below 10 psig (0.7 barg).b. Gas with specific gravity less than 0.35 or greater than 1.5.c. Applications such as air compression, under-balanced drilling, natural gas compression for

vehicle fuel, refinery and petrochemical process systems, acid gas, etc.d. Drive systems such as turbines, belt drive systems, variable speed motors, etc.e. Non-lubricated compressor cylinders.f. Special unloading or control systems.

Page 2-2 of 2 REV: 5/13

g. Wet gas (natural gas produced along with crude petroleum in oil fields or from gas-condensatefields; it contains methane, ethane, propane, butanes, and some higher hydrocarbons such as pen-tane and hexane). See TABLE 6-5.

h. Discharge pressures above 2500 psig (172.4 barg).7. Some calculations in the Ariel Performance Program may need additional explanation:

a. De-Activated Stage of Compression: In choosing this option during the selection procedure,the program estimates horsepower and flow losses for a de-activated stage.

b. Cylinder Blow Through: For this condition, the program generates estimated results.c. Gas Property Calculation: The program calculates gas properties based on either:

• The gas analysis components entered.• The specific gravity entered, assuming a gas composed of typical natural gas components.

Non-typical natural gas mixtures require entry of the complete gas analysis to yield proper com-pressor performance results.

Guaranteed PerformanceObtain all guaranteed performance in writing from Ariel.Ariel guarantees a single design point as calculated by the current version of the Ariel PerformanceProgram for each compressor manufactured. All other performance is "expected" and not guaranteed. Agas analysis is required to validate this guarantee. At this guarantee design point, performance is basedon gas conditions at the cylinder flanges free of pulsation effects.Rated capacity and power are guaranteed to a tolerance of ± 3% for specific gravity between 0.50(14.482 molecular weight) and 0.80 (23.171 molecular weight).Rated capacity and BHP are guaranteed to a tolerance of ± 6% for any one or more of these conditions:1. Specific gravity greater than 0.80 (23.171 molecular weight)2. Specific gravity less than 0.50 (14.482 molecular weight)3. Suction pressure less than 10 psig (0.7 barg)4. Discharge pressure greater than 2500 psig (172.4 barg)5. Compression ratios less than 1.8Where:• Molecular or Molar Weight of dry air (U.S. Standard Atmosphere) = 28.964• Molecular Weight = Relative Molecular Mass• Specific Gravity or Relative Density = Molecular Weight of gas divided by 28.964

Performance Testing1. Testing for guaranteed performance must occur within 90 days of commissioning. If the design point

cannot be reached in this time frame, a mutually agreed upon alternate point will be tested.2. In questions of capacity delivered or horsepower consumed by an Ariel compressor, check these com-

mon discrepancies: inlet pressure drop, excessive interstage pressure drop, leaking bypass valves,volume decrease due to liquid drop out, gas analysis different than the quoted gas analysis, com-pressor and driver mechanical condition, driver fuel gas consumption, etc.

3. If doubt still remains, conduct a performance test. Ariel reserves the right to conduct or supervise anyperformance field test. All comparisons to predicted performance will comply with this document.Ariel is not responsible for test costs.

Section 2 - Applications Packager Standards

REV: 5/13 Page 3-1 of 3

Section 3 - Skid Design and FabricationA skid/package mechanical analysis is required to provide a properly engineered system tothe end user. The Packager or a third party conducts the analysis for all unprovendriver/compressor combinations. This is especially critical for projects such as:• Any first of a driver and/or compressor combination.• Any first of a frame class.• Offshore platforms.• FPSO installations.• Pile-mounted skids.

NOTE: The Packager must retain any supporting calculations made by the Packager and/orconsultant. The Packager must consider dynamic as well as static forces. Combined RodLoad and Unbalanced Forces and Couples data are available within the Ariel PerformanceProgram.

Package Design Requirements1. The skid/pedestal should transmit shaking forces to the foundation and provide adequate structural

support with proper tie-down under piping, and other critical components.2. Provide sufficient skid stiffness and strength so the compressor mounts flat without bending or twist-

ing the compressor frame, crosshead guide, or cylinder. All frame and crosshead guide mountingpoints should be supported by full depth cross members.

3. When installing equipment to the skid, ensure all mounting points are flat and parallel to compressorfeet to avoid angular and parallel soft foot and facilitate ER-82 compliance (see Appendix H). Themounting method depends heavily on packager ability to duplicate skid flatness at installation. Meth-ods to mount the frame to the skid include:• Grouted sole plates• Grout chocks• Careful rail or full bed grouting• Welded steel chocksNOTE: Flatness and parallelism can be difficult to achieve using this method. It is rec-ommended to machine steel chocks after welding to avoid angular soft foot, whichrequires the use of step shims or re-machining in the field. Step shims create point load-ing and will not provide adequate contact between the foot and chock.• Threaded adjustable chocksNOTE: Though threaded adjustable chocks have been used with success under smallerframe classes, they are not permitted under JGC:D:Z:U:B:V and KBZ:U:B:V frames. Keepin mind the compressor frame is to be the stationary component of the alignment train.

4. Provide compressor hold down bolting in accordance with ER-26 (see Appendix A ). Bolt lengthsextending through only the compressor foot and I-beam flange are typically insufficient to preventloosening.

5. Support crosshead guide feet not only to provide vertical support, but also to prevent horizontal move-ment perpendicular to the piston rod. Attaching any support to the deck plate alone is insufficient.Ariel recommends A-frame supports attached directly to a full depth skid member. Ariel offers cross-head guide supports for JGW and larger frames. Use of threaded adjustable chocks to support thecrosshead guides requires a careful mechanical study to validate their use.

Page 3-2 of 3 REV: 5/13

6. JGH:E:K:T 2-throw frames with pipeline cylinders and all JGC:D and larger 2-throw framesrequire a full width compressor pedestal (wide enough to include the guide support mount-ing feet) to control unbalanced forces and couples. Ariel recommends a reinforced concrete-filled pedestal of common height and use of Ariel crosshead guide supports.

7. Each crosshead guide deflects an amount relative to the weight of the cylinder mounted on thatthrow. See the Ariel Performance Program for estimated crosshead guide foot deflection. This esti-mate accounts only for cylinder weight. Account for the weight of attached bottles and piping if cor-recting after bottle mounting. For JGR:J:W and smaller frames, cylinder weight will not deflect theguide, but bottle weight still requires consideration. After mounting the frame and torquing the framemounting bolts, shim the crosshead guide to achieve zero deflection when the guide support bolts aretightened. Loosen the guide support bolts, lift the cylinder, then add shims equaling the deflectionvalue as calculated by the Ariel Performance Program to the shim pack under the crosshead guide tolevel it. Tighten guide support bolts per ER-63. Shims may need adjustment so crosshead top and bot-tom clearances and piston rod run out are within tolerance (see Ariel Maintenance and Repair Man-ual). Except for KBZ:U frames, shim crosshead guides between the guide feet and the support; shimKBZ:U guides under the support. On JGZ:U frames equipped with long two-compartment (L2) cross-head guide extensions, use the outboard feet under the guide extension to support the guide. Leavefeet under the guide unsupported.

8. Provide sufficient skid stiffness to prevent twisting due to torque reaction between the driver and com-pressor. Provide enough stiffness so shipment or relocation minimally affects driver/compressor align-ment. Always check and correct coupling alignment after package relocation.

9. Every installed compressor package has several mechanical natural frequencies (MNF), usually inscrubber/bottle/cylinder system groupings. Each frequency is a function of the stiffness and mass ofthe entire system, including the foundation or deck.If the system first MNF is within the operating speed range or twice the operating speed range of thepackage, resonant vibration occurs. Ensure the first MNF of the skid package mounted on the userfoundation or deck is either less than 0.8 times the minimum compressor operating speed, or morethan 2.4 times the maximum operating speed. Coordinate with the foundation or deck designer.Although not recommended, to tune a major cylinder MNF between 1 and 2 times the operatingfrequency, maintain the cylinder MNF above 1.5 times operating frequency. The high excitation of 1times compressor forces combined with low level amplification up to 1.5 times the operatingfrequency can cause excessive vibration.Forward maximum/minimum speed and normal operating speed range to the end user along with acaution to examine off-skid structure, piping, instrumentation, and equipment for resonance.

10. Provide skid beams with gussets at anchor bolt locations. Anchor bolt locations should also be sup-ported internally by cross members.

11. Well-designed crosshead guide supports provide high axial (parallel to the crankshaft) and verticalstiffness that usually eliminate the need for head end cylinder supports (HES). If a mechanical anal-ysis predicts interference with a cylinder/guide combination MNF in the operating speed range, HESmay be recommended. Use HES to supplement well-designed crosshead guide supports.• The mechanical analysis provider should provide detail drawings of the cylinder support of appro-

priate stiffness to shift the MNF.• It is a good practice to design provisions for HES into a skid, even if HES are not recommended. It is

relatively inexpensive to fabricate and correctly install HES if considered in the design phase.• HES require careful adjustment and may hinder maintenance access. Improperly adjusted HES

can cause high stress on cylinders and fabricated process piping that can result in failure.• HES are also recommended for vertical support of cylinders weighing over 10,000 lbs.

Section 3 - Skid Design and Fabrication Packager Standards

• Some cylinders have a small pad on the bottom of the head end of the cylinder. This can be usedwhen only vertical support is required.

Head End Support Required Features• HES must be adjustable to avoid cylinder stress. Adjust HES with the compressor at operating tem-

perature.• HES must be very stiff vertically and as stiff as possible parallel with the crankshaft.• HES must not be excessively stiff horizontally (parallel with the rod). They are not intended to

restrain rod load forces.• Ariel recommends “clamp” style supports for most Ariel cylinders. “Clamp” style supports grip the

flange of the head end head or clearance pocket. For clamp style HES, it is critical to machine theinside diameter of the clamp to a very tight tolerance to provide as much contact area as possible.

• Attach the vertical support of the HES to the skid beam web section, not to the flange. Gussets arerequired between the beam flanges.

NOTE: Supports that use gas containment bolting to attach to the cylinder require Arielapproval.

Head End Support AdjustmentAdjust the HES with the system heat-soaked and immediately after adjusting the bottle supports inaccordance with the start up checklist and the maintenace schedule. Shim or otherwise adjust thesupport to hold the current position of the cylinder.NOTE: Piston rod run out and crosshead running clearance checks will confirm guide/cyl-inder alignment has not been compromised.

Section 4 - Process Piping SystemsProcess Piping SystemsScrubber Design and Installation Requirements1. Liquids and particulates are incompressible and can negatively impact compressor performance and

reliability. Each stage of compression requires an upstream scrubber or some other device toremove both free and entrained liquids from the gas. The scrubber requires a high liquid level pro-tection system and an automated drain system. In case of abrasive particle carry-over, contact anexperienced filtration system manufacturer for assistance. A debris sample may be required to deter-mine its properties, origin, and appropriate filtering techniques.NOTE: Non-intercooled, dry gas stages of compression may not require liquid separation,but provisions must be made to remove lubricating oil, if applicable.

2. Design and construct scrubbers in accordance with good engineering practice and industry stand-ards for two-phase separators and pressure vessels. ISO-13631 provides scrubber specifications.Provide full diameter skirts with a thickness equal to or greater than the vessel wall thickness (mini-mum 1/2 inch (13 mm)).

3. Support scrubbers with full-depth structural members.4. Position all scrubber attachments such as relief valves, sight glasses, instrumentation, drain lines,

and tubing close to the scrubber and support as required. Bullseye style sight glasses are rec-ommended.

5. Ariel requires nozzle reinforcement pads or long weld neck flanges.

Piping Design, Installation, and Package ConstructionRequirements1. During package fabrication, ensure no grinding dust, weld slag, sand, or rain enter the

compressor. When welding on the skid, attach ground connection close to the weld andnever to the compressor.

2. Design and install piping without low points that could collect liquids between the scrubber and cyl-inder; liquid slugging can result in compressor damage.

3. Design and install piping so it does not distort cylinders and/or crosshead guides. To confirm the pip-ing imposes no distortion, check crosshead-to-guide clearance after connecting the installed unit tovessels and piping.a. No forces or moments should exist on cylinder flanges during assembly. Prying to align flange bolt

holes or “drawing down” to pull piping into position is unacceptable. Before torquing, flange boltsshould thread by hand with no flange contact. The flange gap without torque must not exceed0.030 inch (0.76 mm) for one gasket or 0.060 inch (1.52 mm) for two gaskets with an orifice.

b. Thermal studies often require nozzle load limits, which are difficult to obtain for the manycylinder/guide combinations and skid designs. Contact Ariel for limitations.

c. It is impractical to perform thermal analysis on a compressor with the cylinders considered rigid.The Ariel bore deflection limit is 0.001 inch per inch (0.001 mm per mm) of bore diameter, whichmay be used as a cylinder deflection limit.

Page 4-2 of 5 REV: 5/13

d. Most unacceptable cylinder deflection comes from severe pipe/bottle misalignment or improperguide preloading. It is rare for thermal loads alone to cause significant deflection, but they can exac-erbate these problems. Unacceptably high flange forces can cause:• Low crosshead-to-guide clearance• Low piston-to-bore clearance• Low crankshaft thrust clearance• High rod run out• Possible cylinder knock

e. Most piping and nozzle failures are due to piping vibration. It is far better to design “on skid” bottles,pipe, and bracing as stiff as possible to prevent mechanical resonance at low frequencies whereexcitation forces are highest, than to design a “soft” piping system to allow thermal growth for “onskid” piping. Consider thermal forces if using long runs of “off skid” piping. “Off skid” piping bettertolerates thermal stress limiters (thermal loops, flexible bracing, etc.) because pulsation and othershaking forces are typically attenuated. Design piping with sufficient size to provide equal flow tocylinders in parallel.

4. Design piping in accordance with good engineering practice and industry standards regarding pres-sure and temperature rating, settle out pressures, flow velocity, pressure drop, and material com-patibility with the gas stream.

5. Provide a blow-down vent to safely relieve system pressure for maintenance purposes. Provide aback-flow prevention check valve for any vent or blowdown line connected to a common vent or flareheader.

6. Support and clamp piping in accordance with good engineering practice. Directly attach supports to,or directly support them by a structural member of the skid or foundation. Support from deck plate orunistrut clamps is insufficient.

7. Use gusseted band clamps with Fabreeka or an equivalent material between the clamp and pipe toprevent fretting and corrosion. Some engineering study providers may dictate metal-to-metal contact.Do not use U-bolt style clamps.

8. Ensure piping rests on the support and is not pulled down by the clamp. Shim if needed.9. Do not block access to the analyzer drive connection at the crankshaft centerline on the crankcase

auxiliary end.10. Provide visual access to crankcase oil level sight glass and distribution block cycle indicators.11. Before start-up, install inlet gas debris cone strainers with 100 mesh per inch (150 micron) screen and

perforated metallic backing in a pipe spool between the inlet scrubber and cylinder suction flange. Toprotect the compressor cylinder, thoroughly clean any piping or vessels downstream of the screen ofall debris. Clean inlet screens regularly. Monitor inlet debris strainers by differential pressure andclean them before differential pressure approaches screen collapse pressure. To protect againstscreen collapse, use high differential pressure alarm/shutdown switches.

Pulsation Bottles1. High acoustical pulsation can increase frame, cylinder, gas piping, and equipment vibrations. An

acoustical study will determine if the package requires pulsation bottles when not already required bycustomer specifications. An acoustical study will determine if acoustical or mechanical resonancesexist that require correction. When analyzing acoustical pulsation responses, consider single-actingcylinder and all cylinder load steps. Single-acting cylinders can present the worst case scenario foracoustical analysis. High acoustically driven vibration can result from single-acting cylinder operationwhen not considered. Contact Ariel for information beyond that of the Ariel Performance Program.

Section 4 - Process Piping Systems Packager Standards

2. Design and construct pulsation bottles in accordance with good engineering practice and industrystandards for either piping and/or pressure vessels.

3. Design pulsation bottles without traps. Traps allow liquids to accumulate resulting in liquid slugging.Provide taps for drains and instruments on the bottles. Nozzles protruding into the bottle should beslotted to prevent liquid accumulation.

4. Install taps for temperature and pressure monitoring as close to the compressor cylinder as possible.Install the discharge temperature shutdown probe in the 1/2" NPT tap in the cylinder discharge noz-zle provided by Ariel.

5. Position all bottle attachments such as relief valves, sight glasses, instrumentation, drain lines, andtubing close to the bottle and support as required.

6. Construct pulsation bottles connecting two or more cylinders so as not to strain cylinder flange con-nections or distort cylinders.

7. Ariel requires nozzle reinforcement pads.8. If a mechanical/acoustical analysis predicts high bottle shaking forces, engineered bottle supports

and clamps may be recommended. Bottle supports may not be required on some units if the Pack-ager meets the following conditions.a. Piping and bottles assembled to cause no strain on cylinder flanges during compressor operation.b. Crosshead guide mounting feet firmly supported and properly aligned.c. Piping properly tied down.d. Scrubber, piping, or any other skid attachment vibration at a natural frequency prevented during

compressor operation.

Pulsation Bottle Installation1. Place primary discharge bottle on its adjustable supports in the lowest position. Ensure both cylinder

and bottle flange sealing surfaces are clean and free of damage prior to installation.2. Adjust primary discharge bottle supports to raise bottle to within 0.125 inch (3 mm) of cylinder flange.

3. Lubricate and insert flange bolts to allow feeler gauge access at 0°, 90°, 180° and 270°. Confirm nobolts are flange-bound and all bolts can be threaded in completely by hand.

4. Tighten flange bolts to 45–50 ft-lbs (61-68 Nm) to achieve metal-to-metal flange contact withoutexcessive force applied to the nozzles or cylinders.

5. Record preliminary feeler gauge readings at 0°, 90°, 180° and 270° per flange.6. Place primary suction bottle on cylinders and install bolts as previously described for the discharge

bottle.7. Verify and record all feeler gauge readings.8. Minor adjustments to cylinder flange rotation are possible at this time. If this is necessary, crosshead

clearance and piston rod runout must be re-verified.9. No forces or moments should exist on cylinder flanges during assembly. Prying to align flange bolt

holes or “drawing down” to pull piping into position is unacceptable. Before torquing, flange boltsshould thread by hand with no flange contact. The flange gap without torque must not exceed 0.030inch (0.76 mm) for one gasket or 0.060 inch (1.52 mm) for two gaskets with an orifice.

10. Loosen bottle-to-cylinder flange bolts and install gaskets. Confirm no bolts are flange-bound and allbolts can be threaded in completely by hand.

11. Tighten all bolts in the following sequence:

Packager Standards Section 4 - Process Piping Systems

REV: 5/13 Page 4-3 of 5

Page 4-4 of 5 REV: 5/13

a. Apply 25% of torque in criss-cross sequence. Tighten repeatedly as required for consistent torqueon all bolts.

b. Apply 50% of torque in criss-cross sequence. Tighten repeatedly as required for consistent torqueon all bolts.

c. Apply 75% of torque in criss-cross sequence. Tighten repeatedly as required for consistent torqueon all bolts.

d. Apply final torque to all flange bolts until consistent torque is achieved on all bolts.12. Loosen primary discharge bottle adjustable supports in preparation for piping fit and startup.

Discharge Bottle Support AdjustmentProperly adjust bottle supports in accordance with the start up checklist and the maintenance schedule.Ariel recommends using the following procedure:1. With the system heat-soaked, shut down the compressor. Loosen the bottle supports and head end

supports (if applicable) so there is no contact between the bottle and support.2. Place a magnetic base indicator as close as possible to the bottle support with the magnetic base on a

structurally stiff skid member. Place the indicator needle at the bottom center of the bottle. Multiplesupports on a single bottle require an indicator at each support.

3. Tighten the bottle supports only until there is a positive movement on the indicator: 0.003 to 0.005inch.

4. Remove the indicators. Use a locking mechanism to prevent support bolting from loosening or repo-sitioning if the supports do not contact the bottle when the equipment cools.

5. At this point, adjust head end cylinder supports (if applicable). See “Head End Support Adjustment”on page 3-3.

Relief Valves1. Provide relief valves on the initial stage suction and the discharge of every stage of compression, set

to operate in compliance with ISO-13631. Install discharge relief valves upstream of each individualgas cooler section.NOTE: Consider all possible types of equipment failure or poor operation and protection of piping sys-tems when selecting relief valve locations and settings.

2. Ensure adequate relief valve settings as well as cylinder and component MAWP's for process settle-out pressures during shutdown.

3. Pilot operated relief valves must include a back-flow protection feature when connected to a commonvent line.

The compressor cylinder may or may not be the system component with the lowest pres-sure rating. Set relief valve based on the lowest rated connected equipment.

Gas Coolers1. Determine if the package requires gas cooling if not already required by customer specifications. Con-

sider ambient conditions, anticipated operating conditions, geographical location, and customerrequirements.

2. The discharge gas temperature predicted by the Ariel Performance Program is the expected tem-perature at the compressor cylinder discharge flange. Account for any heat loss between the com-pressor cylinder and cooler inlet flanges and size the cooler accordingly.

3. Account for cooler fan power consumption when engine driven.

Section 4 - Process Piping Systems Packager Standards

4. Cooler design and construction must comply with good engineering practice and industry standardsfor heat exchangers.

5. Consider associated liquid condensates in the cooler design. This includes both heat load and gasflow from top to bottom through the cooler sections.

6. Some applications require automated temperature control to avoid excessive condensates anddense phase above critical point. Applications may include heavy gases, CO2, acid gas, etc.

Section 5 - Driver Power Rating, Couplingand Drive SystemDriver Power Rating1. The motor power rating for electric motor-driven units, including service factor (if any), must be a mini-

mum 110% of the greatest power required for any specified operating conditions. Operating con-ditions include start-up, off-design process variations, and peak loading conditions. Considerpotential excessive horsepower due to external gear and coupling losses along with process gas ves-sel, piping, and/or orifice losses. See specific electric motor application requirements under "Tor-sional Analysis" below.

2. Size internal combustion engine rated power for the greatest power required for any of the com-pressor operating conditions plus accessory power for the specific location. Do not exceed theengine manufacturer's rating criteria for continuous duty service. This criteria specifies the amount ofload and speed to apply without interruption after considering site altitude, temperature, and fuel gascomposition.

Electric Motors1. Inform motor manufacturers that reciprocating gas compressor torque varies considerably in one rev-

olution. An Ariel compressor is not a constant-load (uniform torque) device, even if driven at a con-stant speed. In severe service, peak torque may vary ±200% of the mean, repeating as often as threetimes per revolution. Torque peaks and torque reversals can cause motor shaft fatigue failure, espe-cially with a keyway. Ensure motor shaft strength suitability for all operating conditions of intendedservice. Larger Ariel compressors require robust motors with large diameter, keyless shafts for longlife and successful performance.

2. When designing the motor rotating assembly, electric motor manufacturers must account fordynamic (alternating) torques generated by the driven equipment as well as the mean torque.

3. The motor stub shaft must be only as long as needed to fully insert in the appropriate coupling huband ensure complete contact.

4. The motor stub shaft and the section thru the drive end bearing should equal or exceed the com-pressor drive stub diameter. For keyless compressor drive stubs, an equivalent diameter keyedmotor shaft may not be sufficient (see FIGURE 5-1).

FIGURE 5-1 Motor Shaft to Drive Stub Coupling

5. Analyze the drivetrain to ensure there are no dangerous vibratory stresses and that current pulsationfalls below motor or switch gear limits. It is inadequate to simply specify a past satisfactory motorframe size; prove rotor inertia and shaft strength and stiffness are equal to a past satisfactory instal-lation before omitting torsional analysis.

Page 5-2 of 4 REV: 5/13

Torsional AnalysisA torsional analysis is required to provide a properly engineered system to the end user free of anypossible torsional concerns. Ariel does not conduct torsional analyses. The Packager or a third partyconducts the analysis for all unproven drivetrain combinations or loading, such as:• All electric motors, fixed or variable speed.• Steam or gas turbines.• Gearboxes.• Engines not previously coupled to a specific compressor frame.• High torque reversals.

Contact Ariel Application Engineering for unit specific information or a list of possible engineering firmsthat can perform the analysis, but there is no restriction to only these companies. A torsional analysisshould include:1. A comprehensive report, including an executive summary, introduction and purpose, analysis lim-

itations, reference documents, computation results, discussion, conclusions, and appendices (tables,figures, and other data).

2. A complete dynamic model of the electric motor shaft, coupling, and compressor formulated in termsof lumped inertia and massless springs based on normal engineering practice and judgment to deter-mine motor shaft flexibility from manufacturer supplied information - all included in a report appendix.Data should also include computed significant natural frequencies of torsional vibration, along withtheir modal deflected shapes and a speed-frequency interference diagram.

3. Governing torque-effort curves identified from expected compression service and rank-ordered forexcitation potential with each curve harmonic content specified in terms of Fourier Coefficients. Con-sider high volume clearance devices and single acting cylinder operation when analyzing torsionalresponses. Single acting cylinders can present a worst case scenario due to a more dynamic torqueeffort curve.

4. A written assessment of natural frequency placements acceptability relative to excitation potentials.5. If required, a forced, damped dynamic model assembly that includes estimates of damping at various

locations in the motor and compressor.6. The dynamic model with appropriate excitations of all governing torque curves applied.7. Dynamic deflections, torques, and shear stresses determined for the entire dynamic model.8. An industry-recognized fatigue analysis of Ariel's compressor crankshaft utilizing a modified Good-

man Diagram.9. An industry-recognized fatigue analysis of the major portion of the electric motor shaft utilizing a mod-

ified Goodman Diagram.10. An auxiliary equipment check for sensitivity to the anticipated torsional activity.11. An on-site torsional vibration measurement at equipment start up to confirm the analysis.

Coupling and Drive System1. The maximum coupling size for each Ariel compressor frame model is predetermined by most cou-

pling manufacturers or torsional providers. The crankshaft stub shaft length shown on the outlinedrawing matches a standard industry coupling size. Do not use a coupling hub design that does notcompletely engage or overhangs the compressor stub shaft length unless it is thoroughly checked bytorsional and stress analyses.

Section 5 - Driver Power Rating, Coupling and Drive System Packager Standards

2. For all direct drive units (engine or motor), use a torsionally rigid, flexible disc coupling similar to theThomas or Formsprag types, unless thoroughly checked by torsional analysis.

3. Do not use couplings that grow and shrink axially due to torque loading.4. See the coupling manufacturer instruction manual for specific coupling installation and operation

requirements.5. Determine the appropriate interference fit between the coupling hub and the compressor shaft to

transmit torque at all operating conditions. The torque load is considered a "heavy" or "heavy alter-nating" load. Ensure the coupling hub and shaft are clean and dry before installation. If a shrink diskor other externally applied interference mechanism is used to ease hub removal, the packager andcomponent vendor must verify the coupling can transmit the required torque without slipping orembedding into the compressor stub shaft.

6. Perform an on-site torsional vibration measurement on compressors driven by variable speed elec-tric motors. Test through design speed ranges and anticipated cylinder unloading steps as soon afterstart-up as possible to confirm theoretical analysis results.

FIGURE 5-2 Angular Coupling-Hub Face AlignmentTIR Limits

7. To ensure parallel and concentricdrive train alignment, position con-nected equipment so total indi-cator reading (TIR) is as close tozero as possible on the couplinghub faces and outside diametersat normal operating temperature.Do not exceed 0.005 inches (0.13mm) on the face and outside dia-meter, except for outside dia-meters above 17 in.

Section 6 - LubricationProper lubrication is vital to compressor operation and requires special attention in package design. Twoindependent systems lubricate a compressor; the frame oil system and the force feed system. The frameoil system is a pressurized circulating system that supplies oil to the crankshaft, connecting rods, andcrossheads. The force feed system is a high-pressure injection system that supplies small quantities of oilto the piston rod packings and piston rings.In a compressor, lubrication:1. Reduces friction - Decreases energy consumption and heat generation.2. Reduces wear - Increases equipment life and decreases maintenance costs.3. Removes heat from the system - Cools moving parts and maintains working clearances.4. Prevents corrosion - Generally provided by additives rather than the base lubricant.5. Seals and reduces contaminant buildup - Improves gas seal on piston and packing rings, and

flushes away contaminants from moving parts.6. Dampens shock - Reduces vibration and noise and increases component life.Many types of oils exist, some petroleum based, others synthetic. Each oil exhibits differentcharacteristics that suit it for a specific application.

Lubricant TerminologyVISCOSITY - Measures fluid resistance to flow. It decreases with increasing temperature. In thisdocument, viscosity is expressed in centistokes (cSt). Proper viscosity is the most important aspect ofcompressor lubrication. FIGURE 6-4 illustrates viscosity differences between base stock types.Viscosity can increase with oxidation or contamination by a liquid of higher viscosity or decrease withcontamination by hydrocarbon gas condensate or other liquid of lower viscosity. Oil degradationincreases viscosity, unless it is multi-viscosity oil (such as SAE 10W40). In multi-viscosity oils, theviscosity improvers degrade, not the base oil itself.VISCOSITY INDEX - Indicates the magnitude of viscosity change with respect to temperature. Thehigher the viscosity index, the less viscosity decreases as temperature increases.POUR POINT - Specifies the lowest temperature at which oil flows. It is important in cold weatherapplications and in cylinder and packing lubrication with cold suction temperatures.FLASH POINT - Specifies the lowest temperature at which oil vaporizes to create a combustible mixturein air. If exposed to flame or high temperature, the mixture flashes into flame and then extinguishes itself.This is important in high temperature applications where oil may mix with air.

ComponentsOil StrainerAn oil strainer installed upstream of the pump prevents debris from entering the pump and damaging it.Ariel supplies a 30 mesh (595 microns) on all JG:A:M:N:P:Q:R:J:H:E:K:T compressors and a 40 mesh(400 microns) strainer on all JGC:D:Z:U, KBB:V:Z:UJGM:N:P:Q compressors. It is located on theauxiliary end of the crankcase below oil level. For dry sump frames, the lube oil strainer ships uninstalledfrom the factory. The packager installs it in the piping later.

Oil Pump & Regulating ValveThe oil pump constantly supplies oil to alljournal bearings, bushings, andcrosshead sliding surfaces. Thecrankshaft drives it by a chain andsprocket to provide adequate oil flow tobearings when the compressoroperates at the minimum speed rating(typically half of maximum rated speed).JG:A:M:N:P:Q:R:J:H:E:K:T:C:Dcompressors maintain oil pressure witha spring-loaded safety relief valve withinthe pump head. To adjust, remove the dust cap to expose the safety relief valve adjustment screw.JGZ:U and KBB:V:Z:U compressors maintain oil pressure with a separate regulating valve. Ariel sets thespring-loaded safety relief valve within the pump head to about 75 psig (5.2 barg) to prevent high oil pumpdischarge pressures that could damage the pump. Do not adjust the pump safety relief valve except witha new pump installation.

Oil CoolerAn oil cooler is required to remove heat from the frame lube oil.When sizing an oil cooler, considertemperature and flow rate of both cooling medium and lube oil. Insufficient cooling water flow rate is theprimary cause of high oil temperatures. Mount cooler as close to the compressor as possible with pipingof adequate size to minimize pressure drop of both lube oil and cooling medium.

The Application Manual lists required cooling water temperature and flow rate to properlycool oil with Ariel supplied coolers. The Ariel Performance Program lists oil heat rejectiondata for each frame in the frame details section (contact Ariel for details).


Thermostatic control valve configuration may vary fromthis schematic depending on valve size. Valve con-nections A-B-C are marked on the valve.

FIGURE 6-3 Thermostatic Valvein Mixing Mode

Oil Temperature Control ValveThe lube oil system requires a thermostatic valveto control compressor oil temperature. Athermostatic valve is a three-way valve with atemperature sensitive element. As the oil heats,the sensing element opens the third port in thevalve.Ariel recommends a thermostatic valve with a170°F (77°C) element. Install the valve in mixingmode to more directly control oil temperature intothe frame (see FIGURE 6-3).

Oil FilterAll compressor frames require oil filters to remove particle contamination that can damage equipmentand oil. Contaminants that damage equipment include wear particles from equipment , airborne particlessuch as dust or sand, and particulates in new oil. Contaminants that damage oil include oxidized oilcomponents and air bubbles.• Ariel filters are not designed for reverse flow often caused by pumping oil out of the compressor

through the filter. This can invert and tear the filter media, sending dirty oil to crankshaft bearings.• With canister style filters, always drain oil filter housing before element removal or dirty oil will be sent to

crankshaft bearings.• Ariel cartridge filters have a 24 month shelf life from the date of manufacture, and an install-by date is

stamped on the top of each filter. Discard any filter exceeding the install-by date.

JG:A:M:N:P:Q:R:J, JGH:R:K:Y/2/4, and JGC:D/2 compressors ship with simplex, spin-on, non-bypassing, resin-impregnated filters as standard. Spin-on filters carry a 5 micron nominal and 17 micronabsolute rating. The Beta ratings are ß5 = 2 and ß17 = 75. Many spin-on filters fit an Ariel compressor,but very few meet filtration ratings of Ariel filters. Do not use after-market filters.JGE:K:T/6, JGC:D:B:V/4/6, JGZ:U, and KBB:V:Z:U compressors ship with simplex or duplex cartridgestyle pleated synthetic filters as standard. Cartridge filters are rated as 1 micron nominal and 12 micronabsolute filters. The Beta ratings are ß1 = 2, ß5 = 10 and ß12 = 75.

Compressor Pre-lube SystemAriel compressors must be pre-lubed anytime the crankshaft is turned and prior to starting. Ariel stronglyrecommends an automated pre-lube system to extend driveline component life.Ariel requires automated pre-lube systems for compressors that meet any of the following criteria:• Electric motor driven compressors.• Unattended-start compressors, regardless of driver type.• Compressor models JGC:D:Z:U:B:V and KBZ:U:B:V.

See FIGURE 6-1 for pre-lube circuit design.NOTE: The pre-lube return into the frame must be upstream of the oil filter.For on-demand compressor applications, the pre-lube pump can circulate oil continuously through thebearings while on standby.Ariel requirements are based on a pre-lube pump sized for 25% of frame oil pump flow to ensure oil flowto bearings, bushings, and oil-filled clearances prior to turning or start-up (see the Ariel PerformanceProgram for frame oil pump flow rates).


REV: 5/13 Page 6-5 of 20

Page 6-6 of 20 REV: 5/13

Pre-lube pressure shall be 30 psig (2.1 barg) at the oil gallery for a minimum of 2 minutes prior to turningor starting.NOTE: A 10 to 15 minute pre-lube is required after:• Any major driveline maintenance• The main lube oil system is drained• Oil filter replacement

Instrumentation: Automated pre-lube systems require a start permissive logic and instrumentation tosatisfy the minimum required pressure and duration at the oil gallery inlet.It is highly recommended that the compressor low oil pressure shutdown be Class B. Inhibited time shallbe no longer than 10 seconds after idle speed is achieved on gas engines or start initiation for electricmotors.If the compressor fails to achieve 45 psig (3.1 barg) oil pressure within 10 seconds after reaching engineidle speed or electric motor start initiation, ensure shutdown and correct the cause. Repeat pre-lubebefore each start attempt.NOTE: If a compressor fails to start or shuts down at start-up due to low oil pressure, DO NOTre-start until the cause is corrected.

Oil HeatersThe compressor may need a frame oil heater to meet allowable oil viscosity requirements at start-up (seeTABLE 6-4). One possible heating mode maintains the compressor frame at a minimum temperature sothe compressor can start immediately if needed (see TABLE 6-1). Multiply the coefficients listed in by thedifferential between target oil temperature and ambient temperature to obtain the kilowatt rating for aheater.Another mode heats oil from ambient to a minimum temperature prior to starting (see TABLE 6-2).Multiply the coefficients listed in by the rise in oil temperature and divide by target hours to obtain thekilowatt rating for a heater.Ariel recommends circulation heaters for all units. JGZ:U:B:V, KBZ:U:B:V units use circulation heatingonly. Heated oil should circulate through the filter, bearings, and crossheads as well as the sump.All other Ariel compressors have at least one heater connection; four and six throw frames have two.Maximum allowable watt density for an immersion heater is 15 W/in2 (2.3 W/cm2). This limit prevents oilcoking on the heater element, which reduces heater efficiency and contaminates remaining oil.

Oil System CleanlinessClean the compressor frame oil piping system and components of all foreign matter such as sand, rust,mill scale, metal chips, weld spatter, grease, and paint. Use proper cleaning procedures with propercleaners, acids, and/or mechanical cleaning to meet cleanliness requirements. Ariel recommendsflushing all oil-piping systems with an electric or pneumatic driven pump and filtered, clean production oil.Ariel thoroughly cleans all compressor frame cavities prior to assembly and test runs compressors with afiltered closed loop lube system.NOTE: Ariel recommends not disturbing lube oil piping downstream of the installed oil filter.Contaminants that enter this piping or open ports flush into the bearings causing cat-astrophic damage. To remove or alter piping, cover the inlets to the oil gallery, the ends ofthe piping, and the filter outlet so no contaminants enter. Before reinstallation, chemical andmechanical cleaning is required. Flush the pipe in accordance with Ariel cleanliness require-ments (see TABLE 6-3).Prior to start-up, flush all compressors installed with an electric or pneumatic powered pre-lube pumpand less than 50 feet (15 m) of oil piping as outlined below. Include cooler oil passages in the flushingloop. While oil systems for compressors without an electric or pneumatic powered pre-lube pump andless than 50 feet (15 m) of oil piping must be clean, oil flushing is desirable, but not required.For all compressors with oil piping systems greater than 50 feet (15 m), cleaning and flushing must resultin a cleanliness level to ISO-4406, Grade 13/10/9 and/or NAS-1638, Class 5 (see TABLE 6-3), prior tostart-up.1. Prior to assembling lube oil piping, remove scale, weld slag, rust and any other matter that could con-

taminate lube oil. Confirm:• Complete and closed lube oil system.• Crankcase filled to the correct level with appropriate oil.• Proper and correctly installed lube oil filters.• Operational and viewable oil pressure transducer or gauge, oil filter differential-pressure trans-

ducers or gauges, and oil temperature RTD or indicator.

2. Start pre-lube pump. Record oil pressure, oil filter differential-pressure, and oil temperature. Mini-mum oil pressure is 30 psig (2.1 barg) for effective flushing. Do not exceed 90 psig (6.2 barg).

3. Flush continuously for one hour. Oil filter differential-pressure must not increase more than 10% ofmeasured oil pressure into the filter. Record the oil pressure, oil filter differential pressure, and oil tem-

Usea competent oil lab for sample testing.

Frame Oil System OperationFrame LubricantIn the compressor frame, Ariel recommends ISO 150 grade paraffinic mineral oil that provides oxidation,rust, and corrosion inhibition, and anti-wear properties - commonly called R&O oil. SAE 40 weight engineoil is also acceptable, but contains many unnecessary additives.In limited circumstances and with prior approval from Ariel, cold weather installations may use multi-viscosity oils in the compressor frame if the oil supplier certifies the oil as shear stable. The viscosity ofshear stable oil degrades less through use. Most oil suppliers certify oil as shear stable if viscositydegrades less than a certain percentage in specific tests. As a result, multi-viscosity oils are subject to a30% to 50% shorter life than single straight grade oils.Synthetic lubricants are acceptable in a compressor frame provided they meet operating viscosityrequirements outlined in . Compounded lubricants are prohibited in the frame.

ViscosityFor cold ambient temperatures, design the oil system so the unit may safely start with adequate oil flow tothe journal bearings. Successful operation may require temperature controlled cooler by-pass valves, oilheaters, cooler louvers, and even buildings.The minimum allowable viscosity of the oil entering the frame is 16 cSt. Typically, this is the viscosity ofISO 150 grade oil at about 190°F (88°C).

Oil PressureThe factory sets normal pressure on the discharge side of the oil filter at 60 psig (4.1 barg) forcompressors tested mechanically complete (inspector tag displayed). If factory tested as mechanicallyincomplete (no inspector tag), the packager sets normal oil pressure at initial start-up to 60 psig (4.1barg) at the lower of the frame or cylinder rated speed, or driver speed at normal operating temperature.Ariel uses the pump safety relief or separate lube oil pressure regulating valve to regulate pressure intothe compressor. If oil pressure into the compressor at minimum operating speed and normal operatingtemperature does not read about 60 psig (4.1 barg), adjust the pump safety relief or separate lube oilpressure regulating valve. With compressor running at minimum rated speed, turn the adjustment screwclockwise to increase oil pressure, or counter-clockwise to decrease it.


REV: 5/13 Page 6-9 of 20

Page 6-10 of 20 REV: 5/13

The compressor requires a 45 psig (3.1 barg) low oil pressure shutdown for protection.NOTE: If oil pressure drops below 50 PSIG (3.4 barg) when crankshaft speed equals orexceeds minimum rated operating speed, find the cause and correct it.

Oil TemperatureMaintain frame inlet oil temperature as close to 170°F (77°C) as possible. Minimum lube oil operatingtemperature is 150°F (66°C) to drive off water vapor. Maximum allowable oil temperature into thecompressor frame is 190°F (88°C). Higher temperatures increase the oxidation rate of oil. Every 18°F(10°C) within the operating range doubles the oxidation rate of oil.For proper operation of the thermostatic control valve, the maximum differential pressure between thehot oil supply line and the cooled oil return line is 10 psid (0.7 bard).

Oil MaintenanceAn oil analysis program is the most effective way to determine frame oil change intervals. Consistent oilanalysis can identify when to change oil on the basis of need rather than a scheduled interval. Dependingon service, oil analysis can significantly extend oil change intervals.Install a sampling point between the oil pump and filter at an easily accessible location. Minimize dirt ordebris that can collect around it. Use a needle valve to better control pressurized oil flow.Collect and analyze oil samples to verify suitability for continued service. Oil analysis should include:• Viscosity testing at 104°F (40°C) and 212°F (100°C). This verifies that oil has not mixed with cylinder

oils or process gas.• Particle counting to the latest version of ISO 4406.• Spectroscopy to determine wear metals, contaminants, and additives.• FTIR (Fourier Transform Infrared Spectroscopy) to check for oxidation, water or coolant con-

tamination, and additive depletion. This is more important if the sump oil is not consumed by the forcefeed system.

Cylinder and Packing LubricationThe cylinder lubrication system injects lubrication into cylinder bores and packings. The system consistsof an oil supply, an oil filter, a force feed lubricator pump, divider blocks, pressure indicators, check valves,and flow monitoring shutdown devices. The system is progressive; each piston in the divider block mustcomplete a cycle before the system cycles again. This type of system offers better lubrication precisionand eases monitoring.

Force Feed System ComponentsOil Supply FilterAn in-line oil filter is required upstream of the force feed lubricator pumps. When frame lube oil is used forcylinder lubrication, the provided compressor filtration system is adequate. For separate force-feed lubeoil supplies, the packager must install a filter. Ariel recommended filtration is 5 micron nominal. Arielsupplies a secondary strainer/filter at the pump inlet.

FIGURE 6-5 TypicalForce FeedLubricator

Force Feed LubricatorThe force feed lubrication system oilsthe compressor cylinders and piston rodpackings. Oil flows to the 150 micronsintered bronze filter on the suction sideof the force feed lubricator pumpdirectly from the pressure side of theframe lubrication system, or from anoverhead tank. Filtered oil flows to aheader and to pumps on the force feedlubricator.A self-contained oil reservoir oils theforce feed lubricator worm gear andcam. The force feed lubricator sightglass shows the reservoir oil level.

Rupture Disc AssemblyA blow-out fitting with a properly ratedrupture disc is installed at the force feedlubricator pump outlet upstream of theno-flow shutdown. The disc colorindicates its burst pressure and should show through the hole in the fitting. At over-pressure, the discruptures and interrupts the oil flow through the rest of the system. The no-flow device must shut down thecompressor within 3 minutes of the oil flow interruption.

Pressure GaugePressure gauges are installed on all distribution blocks for system monitoring and troubleshooting.

Distribution BlocksDistribution blocks consist of three to seven divider valves and an optional bypass block fastened to asegmented baseplate. O-rings seal between the divider valves and baseplate and between baseplatesegments. Check valves are installed at all lube port outlets.Divider valves contain metering pistons that discharge a predetermined amount of oil with each cycle in asingle line, progressive lubrication system.The baseplate contains the divider valve inlet and outlet connections, interrelated passageways, andbuilt-in check valves. All lubricant piping to and from the distribution block connects to the baseplate. Thebaseplate consists of one inlet block, three to seven intermediate blocks, one end block, and three tierods. The number of baseplate intermediate blocks determines the number of divider valves allowed.Each distribution block requires a minimum of three divider valves.Some systems include primary and secondary distribution blocks. Primary distribution blocks feed two ormore secondary distribution blocks. Connect a no-flow device to the primary distribution block.

Over-Pressure Pin Indicator (Optional)Over-pressure indicators are installed on the front face of divider valves. If the specified lubricantpressure is exceeded in an outlet port, a pin emerges from the front of the indicator, identifying the over-pressured line.

Fluid Flow Monitor and Cycle Indicators (see Section 9)

Balance ValvesBalance valves are used in high differential pressure distribution block applications to reduce systemproblems such as bypassing, no-flow switch errors, or blown rupture discs. Balance valves add pressureto distribution block discharge ports to minimize differential pressure across the distribution block.

Check ValvesSingle ball check valves are provided at the oil gallery and divider block outlets. Double ball check valvesare installed at each injection point to prevent reverse leakage and isolate injection points.

Flushing Oil (Optional)Ariel recommends cylinder flushing oil for sour gas services with 100 ppm and greater H2S content.Flushing oil provides corrosion protection for the suction valve bodies and springs. Ariel suppliesdistribution blocks to inject oil into the cylinder nozzle on the inlet pulsation vessel. Flushing oil lines aretubed to the end of the crosshead guide. The Packager provides lube lines from the end of the guide tothe suction pulsation vessel cylinder nozzle. An atomizer for flushing lube injection can be constructed ofa thermowell with an 1/8” hole drilled in the tip.

FIGURE 6-7 Force Feed LubricationSystem Independent Oil Supply

Independent Oil SupplyWhen cylinders and packing requireoil different from frame oil, the forcefeed lubricator system requires anindependent oil supply system (seeFIGURE 6-7). An elevated tanksupplies pressurized lubricator oil.To prevent force feed oil fromcontaminating compressor frame oil,disconnect lubricator box overflowtubing from the compressor frame anddirect it to an appropriate drainsystem.Independent force feed lube systemsrequire oil with a viscosity below 1100cSt at the lubricator pump inlet.Possible measures to ensure the forcefeed pump is fed with oil during thesuction stroke:• Increase pipe and fitting size from

tank to force feed pump.• Heat the oil.• Pressurize the supply tank.

System CleanlinessA 5 micron nominal in-line oil filter is required between the main lube oil gallery and the force feedlubricator pumps. The compressor filtration system is adequate for systems that use frame lube oil forforce-feed cylinder and packing injection. For separate force-feed lube oil supplies, the packager mustinstall a filter.

Cylinder LubricationCylinder lubrication rates and type are based on operating conditions and gas composition. Severalfactors influence cylinder oil dilution/saturation by process gas. TABLE 6-5 takes the following intoconsideration:1. Process gas composition/Specific Gravity (SG) - usually the higher the SG, the more dilution.2. Discharge gas pressure - the higher the pressure, the more dilution.3. Discharge gas temperature - the higher the temperature, the less dilution.4. Lubricant type - some oils are more prone to dilution than others.If the Ariel lube sheets specify multiple oil grades or types, use the highest grade oil for all cylinders orreconfigure the system to use multiple oils.

Rate Calculation NotesPacking Lube Rate - Double piston rod diameter and treat it like a cylinder to calculate packing luberate. For cylinders with a tail rod, calculate lube rate for each of the two packings separately and add bothvalues toward the recommended total daily lube rate.Lube Points - Cylinders for JG:A:M:P:N:Q:R:H:E:J frames with bore diameters less than 13" (<330mm) have one point bore lube as standard; top and bottom bore lube is available as an original purchaseoption, (except for all Class T cylinders and 1-3/4JG-FS-HE class cylinders, which have standard multi-point lube). Cylinders for all other frames use standard multiple bore lube points. Piston rod packings forhigh-pressure cylinders use two-point lube. For multiple lube points, the required cylinder or packinglubricant divides equally among the lube points.Recommended Daily Lube Rate Calculation ExampleJGJ/2, with Pipeline Quality Natural Gas (see TABLE 6-5), the following actual cylinder bore diametersas shown on cylinder data plate, 1.5 inch (38.1 mm) diameter piston rod, with mineral oil lubricant:13.00"J (330 mm) at 100 psi discharge pressure (6.89 bar). factor = 1.9.75"J-CE (248 mm) at 577 psi discharge pressure (39.8 bar), Crank End. Factor = 1.5.125"J-HE (130 mm) at 1636 psi discharge pressure (112.8 bar), Head End. Factor = 1.25.

a. ppd = pints per day.b. lpd = liters per day.

Lubricator Cycle TimeLubricant flow rates are measured in seconds per cycle of the distribution block. The calculated break-inand normal cycle times are stamped on the lubricator box data plate. These cycle times are calculatedbased on the gas analysis, operating conditions, and applied speed specified in the compressor order. Ifgas conditions were not supplied with the compressor order, the data plate/lube sheet rates default toclean, dry, 0.65 specific gravity, sweet gas and cylinder MAWP. If the applied speed is not specified, thecycle time is based on maximum rated speed of the frame or cylinders, whichever is less. The lube sheetsin the Ariel Parts Book state gas conditions and list the base rate multiplier at each lube point.Break-in Rate - Set the break-in lube rate about twice the recommended daily rate (150% minimum); i.e.set the break-in cycle time about half the normal cycle time (67% max.) to increase lube rate. Maintainbreak-in rate for 200 hours of operation for new equipment, or when replacing packing and/or pistonrings. Contact Ariel if existing pump is incapable of minimum flow rate required.Lube Rate and Speed - Recommended lube rates for break-in or normal operation, in seconds percycle, are calculated at the frame rated speed (RPM) stamped on the frame data plate or the cylinder


rated RPM stamped on the cylinder data plate, whichever is lower. Lube rate reduces with speed, (ascompressor actual running speed decreases, cycle time increases to reduce lube rate):(RPMmax ÷ RPMactual) x cycle time seconds from lube plate = cycle time seconds at actual running speed.Or see the Ariel Parts Book Lubrication Sheets for the Cycle Time (seconds) vs. RPM (compressorspeed) table at various running speeds at stated gas operating conditions and lubricant.Adjusting the cycle time changes the lubrication rate for all the compressor cylinders and packingssupplied by a particular pump. To change the lubrication rate for only one cylinder or packing requiresindividual divider valve changes. Contact your packager or Ariel for information.To set proper force-feed lubricator pump flow rate, read or measure the cycle time from the installeddevice. For a magnetic cycle indicator assembly, time the cycle from initial indicator pin movement at thefully retracted position to the time when the pin returns to the fully retracted position and just begins initialmovement out again. Adjust the lubricator pump to provide the required cycle time.NOTE: Pump output can become inconsistent if the flow rate is set too low.Changes in operating conditions (such as gas properties or pressures, temperatures, flow requirements,or cylinder re-configuration) require lubrication rate re-calculation and possible force-feed lubricationsystem alteration. Consult TABLE 6-5, the Packager, and/or Ariel.

System OperationPurging the Force Feed Lube System1. The system must be purged if any connections have been opened, or before initial compressor start-

up.2. Loosen tubing connections at the inlet of the primary distribution block, cylinder, and packing gland

3. Connect the purge gun to the pump discharge manifold purge port.4. Pump clean oil common to the system into the purge port until no air bubbles flow from the tubing con-

nection at the primary distribution block inlet. Always hold purge gun in a vertical position to avoidpumping air into the system.

5. While bubble-free oil flows at the primary distribution block inlet, tighten the tubing connection.6. Continue to operate the purge gun until no air bubbles flow from the tubing connection at the sec-

ondary distribution block inlet, if applicable.7. While bubble-free oil flows at the secondary distribution block inlet, tighten the tubing connection8. Continue to operate the purge gun until no air bubbles flow from the tubing connections at the cyl-

inder or packing gland injection points.9. While bubble-free oil flows at the cylinder and packing gland injection points, tighten the tubing con-

nections.

Lubricant CharacteristicsLubricant Base StockCommon compressor lubricants include petroleum based oils and synthetic fluids. All lubricantformulations start with base stock. Lubricant additives improve specific properties such as:

• Viscosity Index• Oxidation and Rust Inhibition• Pour Point• Detergency

• Anti-Wear Protection• Extreme Pressure Protection• Friction Characteristics• "Washing" Resistance

Petroleum-Based Lubricants (Mineral Oils)Paraffinic Oils Napthenic Oils

• The most common mineral oil base stock.• West Texas Intermediate or Arab Light.• Solvent refined or hydro-treated.• Higher wax content.• Viscosity Index greater than 90.• Pour point around 25°F (-4°C).

• Better additive solvency.• South Louisiana crude.• Solvent refined or hydro-treated.• Lower wax content.• Viscosity Index less than 80.• Lower Pour Point than paraffinic oils.

Synthetic LubricantsSynthetic lubricants are man-made with more consistent, controlled chemical structures than petroleumlubricants. They improve viscosity predictability and thermal stability for much higher viscosity indexesthan mineral oils. Additives can modify all common lubrication characteristics to meet or exceed mineraloil performance. Three major synthetic lubricants exist: PAO, Diester, and PAG.NOTE: Most synthetic lubricants of proper viscosity are acceptable for Ariel compressors.Check with the lubricant supplier or Ariel before using ANY lubricant, or for questions aboutlubricant applicability.

Polyalphaolefins (PAO) - Synthesized Hydrocarbons• Compatible with mineral oils.• Most of the same properties as mineral oils.• Requires additives to improve detergent action and improve seal compatibility.• Soluble in hydrocarbon gases. • Low Pour Point.• High Viscosity Index of about 150 cSt. • High Flash Point.

Organic Esters - Diesters and Polyolesters• Compatible with mineral oils, PAO and PAG oils.• Incompatible with some rubbers (O-rings), plastics, and paints; compatible with Viton.• Higher Viscosity achieved with additives or blending with heavier oils.• Primarily used in air compressors. • Low Viscosity of about 85-90 cSt at 40°C.• Leaves a soft carbon deposit when oxidized. • Breaks down in water.• Higher Flash Point than mineral oils. • Low Viscosity Index of about 70 cSt.


Polyalkylene Glycols (PAG)• Very good for high pressure applications.• Does not foul reservoirs. Excellent for reinjection applications.• Resistant to hydrocarbon gas dilution.• Most are water soluble, verify application with lubricant supplier.• Not compatible with mineral or PAO oils, some plastics and paints.• Requires complete system flush when changing to or from mineral or PAO oils.• Compatible with Viton and HNBR.• Poor inherent oxidation stability and corrosion protection - requires additives.• Not recommended for air compressors.• Very high Viscosity Index greater than 200 cSt.

Lubricant FormulationsA single base stock can yield many different oils by changing additives. Most oils can be formulated witheither a mineral oil or synthetic base. Additives can significantly alter oil physical characteristics andsuitability for specific applications. Additives can account for up to 30% of oil volume.

R&O OilRust and oxidation inhibited (R&O) oil is a very good selection for compressor frames and many forcefeed systems. This oil is a very simple oil comprised of base stock, corrosion inhibitors, and anti-wear andantioxidant additives. Base stock viscosity determines finished product viscosity.

Compounded Cylinder OilsCompounded oils are formulated for steam and/or compressor cylinders. They enhance oil film strengthto counter the effects of water, wet gases, solvents, etc. present in gas.Additives contain an animal, vegetable fat, or synthetic base. Animal and vegetable based additives yieldlow oxidation resistance and poor performance at high temperatures. However, most compounded oilstoday use synthetic instead of natural additives.NOTE: Do not use compounded oil in a compressor frame; the additives are incompatiblewith lead based bearing materials.

Engine OilEngine oil is formulated for internal combustion engines. It counteracts negative effects of combustionand helps keep combustion products (soot, water, CO2) away from engine moving parts. It attracts waterand soot and keeps it in suspension until the filter removes it. Some of these additives may provedetrimental to cylinder and packing lubrication. Engine oil additives may include:• Detergents to remove deposits around moving parts.• Dispersants to prevent deposit formation and soot accumulation.• Corrosion inhibitors to prevent rust and corrosion.• Antioxidants to neutralize radicals that oxidize oil.• Anti-wear additives to help prevent metal to metal contact.• Viscosity improvers (primarily for multi-viscosity oil).• Pour point depressants to reduce the temperature at which oil solidifies.

Page 6-20 of 20 REV: 5/13

• Anti-foam agents to help break up foam from air entrainment.

Ash is not an additive; it is a heavy metal residue left over when oil burns. Some detergents, dispersants,and anti-wear additives contain heavy metals like calcium, barium, magnesium, phosphorous, zinc, orsodium. When oil burns on hot engine parts, these heavy metals remain and build a barrier that helpsprevent wear such as valve seat recession.Engine oil works satisfactorily in compressor frames and in many force feed systems for gathering ortransmission applications. Engine oil is usually not the best choice for compressor lubrication. Previousexperience, inventory control, or maintenance simplicity may outweigh benefits of a different oil.Engine oil commonly forms emulsions in the compressor cylinders/piping and can affect performance ofdownstream equipment. Detergent additives allow the oil to suspend water resulting in a gel-like mixturethat does not separate into its components. If gas contains enough water, it mixes with the detergentsand emulsifies. Emulsions usually accumulate in downstream equipment such as scrubbers, but also incylinders and coolers. To eliminate the problem, completely remove all emulsions and thoroughly cleanall equipment. Re-start compressor using R&O oil or some other appropriate non-detergent oil.

Used Engine OilUsed engine oil supplied for cylinders and packing lubrication must meet requirements for cylinder andpacking lubrication and be appropriately filtered (ß5=10 and ß12=75 with an ISO 4406 cleanliness codeof 17:16:14 ). Monitor oil viscosity to verify adequate quality.

Liquids in GasHigher viscosity lubricants or specially compounded lubricants can compensate somewhat for liquids inthe gas stream.For the most effective cylinder and packing lubrication, remove liquids from gas before itenters the compressor. These lubrication recommendations are general guidelines. Ifrecommended lubricants or flow rates appear inadequate, review both. Contact lubricantsupplier for specific lubricant recommendations.

Section 8 - Packing and Distance PieceVent SystemsDistance piece compartments must be vented to a safe location due to potential gas leakage. Thissection identifies some methods to safely route this leaking gas to atmospheric vents, flare systems, orvent gas recovery systems. Special notes:• Remove distance piece covers to confirm internal tubing connection types and locations.• Limit distance piece compartment pressure to 25 psig (1.7 barg).• Do not plug vents to use drains for venting.• Do not reduce the connection sizes provided by Ariel.• Increase to minimum 3/8 inch tubing from the 1/4” NPT connection (see item 3, FIGURE 8-1) for pack-

ing vent/drain.• For a remotely mounted crankcase breather, configure piping to prevent back pressure and piping con-

densation drainage into the crankcase. Do not connect the crankcase breather to a packing and dis-tance piece vent system.

Do not connect the VVCP gas vent to the flare vent system. The flare vent system back-pressure willflow gas back through the VVCP vent and across the stem threads.

FIGURE 8-4 Typical Purge & Vent Packing

Purge and Vent SystemsPurge systems are used in applications that requirebetter gas leakage containment for safety orenvironmental reasons. Units compressing gascontaining more than 100 ppm hydrogen sulfide gas orhydrogen rich gas are common applications for purgegas systems.Common purge gases include sweet natural gas ornitrogen. Do not purge with air. Small amounts of purgegas can leak into the atmosphere through the frame, souse a purge gas that can be permitted to leak in smallquantities.Introduce purge gas pressure at the distance piecepurge connection to the pressure packing case downstream of the packing vent/drain. Maintain purgegas pressure 10 to 15 psi (0.7 to 1 bar) higher than packing vent back-pressure. The higher pressurecreates a barrier to ensure packing gas leakage routes through the packing vent/drain connection.Expected purge rates are 5 cfh (0.14 m3/hr) per purge point.An eductor or vacuum pump can be used to lower the vent system pressure, or to route vent gas tohigher disposal pressures. Set vacuum pressure to a light vacuum (up to several inches of water column)to avoid drawing air into the system.

A long single compartmentdistance piece can beconfigured to reduce gasleakage to the atmospherewith a packing case purgeand a distance piece sweeppurge. Supply the packingcase purge at a pressure of10-15 psi (0.7 to 1 bar)above the packing vent backpressure. Supply thedistance piece sweep purgeat a regulated flow rate of 5scfh (0.14 m3/hr). Thedistance piece compartmentis both purged and vented,allowing the purge gas to“sweep” the compartment.Single compartmentdistance piece configurationcan be used with a pressurepacking purge to controlemissions. A distance pieceflow or sweep purge can beadded for greater reliability.

Piping Manifold SizeConsiderationsWorn or damaged pressure packing rings can result in high vent flow rates and increased back pressureon the vent line. Size venting lines sufficiently to avoid back pressure exceeding 25 psi (1.7 bar) on thedistance piece compartments.When routed to a flare system, review flare upset conditions. Other equipment can provide a large flarepressure that causes back pressure to the distance piece compartments.To avoid back pressure from a short term flare pressure (seconds), install a check valve on the main ventbetween the compressor system and the flare (downstream of the drain pots).Whenever two lines are manifolded together, the combined line size should equal the added areas of theincoming two lines. For example, if two 3/4 inch lines meet, a 1 inch line is appropriate after theconnection. This includes packing vent/drain as well as distance piece vents and drains. Larger sizesmay be necessary to allow proper draining for lines that can contain oil.Size drain lines generously to allow proper draining when adequate slopes are not possible.

Monitoring a Purge and Vent SystemMaintenance of the system and wearing parts is crucial to success. As the packing wears, leakage rateincreases can overcome the application of the purge gas.System monitoring methods include the following (see Section 9 - Instrumentation for additionalinformation):• Packing vent gas temperature out of the packing case.Monitor packing vent line temperature

immediately outside the distance piece. Higher leakage flow rates have higher tubing temperatures. If

immersing a temperature device in the vent line for vent gas temperatures, route the installation to pre-vent the hot oil in the line from contacting the probe as this spikes the temperature.

• Packing case temperature. Install a temperature element in the packing case in lieu of monitoringpacking vent/drain tubing temperature manually.

• Purge gas to vent gas differential pressure.A differential pressure gauge across the purge gasand packing vent/drain line provides a positive indication the vent line flow is not creating more backpressure than the purge gas pressure.

• Packing vent flow.Packing flow measurements must consider the oil in the packing vent/drain lines.Either remove the oil from the line prior to measurement, or install an appropriate flow meter into alarger pipe section where oil in the line is not a concern. An RTD style mass flow meter may be used inlarger line sizes.

• GV1:Gas + actuation gas vent. Vent to safe atmosphere(no back-pressure). Vents any leakage past the primarygas seal. The second seal prevents gas leakage into thecylinder side of the actuator piston. Due to this two seal con-figuration, this vent can be connected to the vent system atlow pressure.

• CM: Actuation gas inlet for control media. Typical controlpressures range from 70 to 125 psig (4.8 - 8.6 barg).Note:Consult Ariel unit specific parts manual or contactAriel for actual control media pressure require-ments. A check valve is required upstream of thesolenoid.• Apply control pressure to CM to close pocket and load cyl-inder end.

• GV2: Vent to safe atmosphere (no back-pressure). Ventsany leakage of actuation media past the primary gas seal.The second seal prevents gas leakage into the atmos-phere. GV2 need not be tubed away if air is the actuation medium.

• AV1: Vent to safe atmosphere (no back-pressure). Vents cylinder side of actuator piston.• GVD:Normally plugged. Use to drain or vent pocket, if needed.

Installation Notes

CAUTION: Install backflow protection between the supply source and the solenoids to pre-vent over-pressure of plant air compressors or other supply sources in the event of actua-tor seal failure.

1. Ariel recommends clean air or inert gas to activate the actuator.2. Do not exceed maximum control pressure as listed on the device. Maximum pressure varies on fixed

volume clearance pockets. Maximum pressure on suction valve unloader actuators is 150 psig (10.34barg).

3. Use minimum 3/8 inch (9.53 mm) O.D. tubing throughout.4. An electrically activated solenoid operating a 3-port, 2-position control valve regulates control pres-

sure. Place control valve to minimize tubing length between the control valve and actuators:• Below 800 RPM, tube length between the control valve and the actuators must be less than 15 feet

(4.57 m).• Above 800 RPM, tube length must be less than 10 feet (3.05 m).

Apply or release control pressure quickly to ensure proper device activation/deactivation:• For suction valve unloaders, less than or equal to three revolutions of the compressor.• For fixed volume clearance pockets, less than or equal to two seconds.

5. The control valve flow coefficient (Cv) must be no less than 1.6. Attach no devices or tubing to theexhaust port that would reduce vent flow.


6. The unloader assembly drawing or part list specifies control pressure required to operate the actua-tors. Ariel recommends monitoring and alarming operating gas pressure to prevent operation belowthis value.

7. Always leave actuator vents open to ensure safe and effective unloader operation. Do not allow paintto block vents.

When process gas is toxic, flammable, or in any other way objectionable in the compressor building, pipethe lower vent to carry any leakage away. Use vent tubing no less than 3/8 inch (9.53 mm) O.D., and ifcombined with any other vent system, allow no back pressure or vacuum in this piping.

Section 9 - InstrumentationPackagers must provide safety shutdowns, controls, and instrumentation to ensure the compressorsystem operates within published Ariel limits. The use of “alarm” instead of “shutdown” for any minimuminstrumentation requirement may result in equipment damage. Additional information for control andinstrumentation may be found in the appropriate Ariel Maintenance and Repair Manual.NOTE: Ariel recommends the use of shipboard or armored cabling as opposed to wiring inconduit to minimize nuisance shutdowns due to wire chafing and shorts. Cable in cable traysalso facilitates maintenance access.

CAUTION: DO NOT drill holes in cylinders or other pressure containing components forany purpose. Epoxy-mounted clamps (to bare metal) for wiring and tubing are a suitablealternative. See Appendix J.

Notes1. Install the compressor frame low lube oil pressure shutdown set to stop the unit if oil pressure down-

stream of the filter falls below 45 psig (3.1 barg). Compressor operation for only a few seconds with-out oil pressure causes major damage. Normal oil pressure is about 60 psig (4.1 barg) at full ratedspeed and normal operating temperature. The low oil pressure shutdown must activate after oil pres-sure exceeds 45 psig (3.1 barg) at start-up. Ariel provides a 1/4 inch tubing fitting to connect the lowlube oil pressure shutdown and ties a tag to this connection before each compressor ships. Do notoperate the compressor for prolonged periods at less than 50 psig (3.4 barg) oil pressure.

2. Automated pre-lube systems require a start permissive to sense minimum required pressure/time atthe oil gallery inlet. See “Compressor Pre-lube System” on page 6-5. The unit must shut down if thesystem fails to achieve 45 psig (3.1 barg) oil pressure within 10 seconds after crankshaft starts to turn.

3. Mount overhead lube oil supply tanks high enough to provide oil flow to the level control at all ambienttemperatures.

4. On multi-nozzle cylinders, Ariel strongly recommends a temperature device in both discharge noz-zles.

5. Install the high lube oil inlet temperature shutdown at the filter inlet connection.

Section 9 - Instrumentation Packager Standards

6. At a minimum, install one vibration shutdown for two and four throw frames and two for six throwframes. Mount vibration devices near the top of the frame with the sensitive axis parallel to the pistonrod axis.

7. Install all safety shutdowns, controls, instrumentation, ignition systems, electrical devices, and hightemperature piping (gas discharge and engine exhaust) in accordance with good engineering prac-tice and applicable codes for the area classification at the end user location. Ensure compatibility ofall systems for area classification.

8. If packing vent temperature is monitored, alarm and shutdown set points should be confirmedthrough vent flow rates.

Ariel Supplied End DevicesCAUTION: Any arc welding on the skid and/or associated equipment and piping can per-manently damage solid-state electronic equipment. Welding can cause immediate failureor reduce electronic equipment life and void the warranty.To protect electronic equipment prior to any arc welding (including repair welding), dis-connect all electrical connections including ground, and remove batteries, or completelyremove the electronic equipment from the compressor.It is good practice to attach the welding ground clamp as close as possible to the areawhere the welding will occur and to use the lowest practical welder output setting. Weld-ing must not cause a current flow across any compressor bearing surface, including butnot limited to crankshaft and crosshead bearing surfaces.

Main Bearing and Packing Case Temperature SensorsThermocouples, Type J (Iron-Constantan) or K (Chromel-Alumel) - A thermocouple is twodissimilar conductors joined together at one end to form a sensor that produces a thermoelectric voltageas an accurate function of temperature. Appropriate controls interpret the thermocouple voltage astemperature.

FIGURE 9-1 TypicalDual Element RTDWiring Diagram

Resistance Temperature Devices (RTD) - An RTD is a sensor thatproduces electrical resistance as an accurate function of temperature.Appropriate controls interpret the electrical resistance as temperature. Atypical measurement technique sends a small constant current through thesensor and measures voltage across the sensor with a digital voltmeter toindicate resistance by a computer and wave-fitting equations.For main bearing temperature sensing, Ariel supplies dual element, six-wire,100 Ohm (at 0°C) RTD’s. Dual element RTD’s allow rewiring instead ofsensor replacement if an element fails. Insulate unused wire ends from eachother and conduit ground.To simplify wiring, RTD's come with two black wires and one green for oneelement, and two red wires and one white for the other. See FIGURE 9-1.A Zone 1 environment may require the installation of proper, intrinsically safeor equivalent protection to fulfill electrical requirements.

Force Feed Lubrication System MonitoringAriel requires the control panel to shut down the unit if a lube distribution block stops cycling duringcompressor operation. Set the shutdown to a maximum of 3 minutes. This is a class B shutdown, defined

as a shutdown unarmed until a short time (typically 2 minutes) after the compressor starts. This allowsdivider blocks time to cycle the first time before the shutdown activates.Ariel requires all force feed lubrication monitoring devices to be grounded back to the control panel earthground, and all unused wires to be individually isolated so they cannot contact each other or externalsources. Improper grounding and wiring can result in unreliable monitor operation, phantom shutdowns,and premature device failure.Ariel offers several lube system shutdown devices. See TABLE 9-2 for specifications on available types.For detailed information about each device, visit the vendor literature section of www.arielcorp.com.

Shutdown SwitchThe shutdown switch monitors divider block pin position and supplies a shutdown contact. If the dividerblock stops cycling for a given time, the switch sends a shutdown signal to the control system.For no flow shutdown devices, Normally Open (NO) refers to the switch state while the divider blockcycles or the unit runs. An NO switch means when the unit runs, the shutdown switch is open or non-failsafe; the control system cannot detect damaged devices or loose or cut wires at startup and will neverstop the unit. A Normally Closed (NC) switch means when the unit runs, the shutdown switch is closed orfailsafe; the control system will detect a loose or cut wire and shutdown the unit.Ariel recommends NC (failsafe) switches. However, when a NO (non-failsafe) switch is used, Arielrecommends testing shutdown circuits at least once a month.

Proximity SwitchThe proximity switch senses divider block piston position and changes switch state or pulses with everyposition change. This device must work with a PLC or some other counter/timer device to produce ashutdown. Some devices open the switch when the pin is in and close when the pin is out. Othersproduce a 0.5 second pulse when the pin moves in and out. With pulses, the control system must senseswitch cycling and stop the unit if a block stops cycling.When using a proximity switch, a local cycle indicator is required for local monitoring of lube cycle times.Ariel recommends a control system set to find the time between triggered cycles when the switchtransitions from off to on. See FIGURE 9-2.1. Shutdown Time with No Lubrication - Distribution block cycle times vary slightly from cycle to

cycle; 12 seconds for one cycle, then 15, then 14 is normal. The recommended shutdown time is dou-ble the design cycle time + 30 seconds, limited between 30 seconds and 3 minutes.Shutdown Time = (2 x design cycle time + 30 seconds)Find design cycle time on the compressor lube sheets or the compressor tag.

2. DE-BOUNCE and Latching Circuits - The device and control system scan time may necessitatede-bounce hardware and/or software. Some devices include no built-in de-bounce circuits and cancause a fast control system to double or triple count. Other times, it may be necessary to latch input toallow the control system to detect only the first transition from low to high. This becomes significantwhen displaying the cycle time for the operator to set pump flow rates and when calculating total oilthrough the divider block.


3. Suggested Operator DisplaysDivider Block Cycle Time - Set lube system pumps according to recommended divider block cycletimes. A display of divider block cycle time in seconds is helpful to adjust lube pumps as they wearout, or to set divider block cycle times at pump replacement.Time Since Last Pulse - It is helpful to display the timer so the operator sees it actively timing.Average Cycle Time - Cycle time varies a few seconds from cycle to cycle. It is sometimes helpful todisplay a cycle time averaged over 5 to 10 cycles.Total Oil Consumed - Displays how much oil the lube system uses for accurate oil orders.

Vibration Protection (packager supplied)Ariel requires sensors to protect the equipment in the event of excessive vibration. Adjust alarm andshutdown levels on site under normal running conditions. Below are typical vibration levels establishedfrom field experience:

Tandem Cylinder <0.70 (<18) <1.0 (<25) <1.0 (<25)

TABLE 9-3 Typical Vibration Levels for Ariel Reciprocating Compressors, inch/sec (mm/s)

1. Ariel does not provide vibration limits for skid piping, bottles, or scrubbers.2. Table does not apply to JGI - vertical non-balanced compressors.3. These figures apply to balanced opposed reciprocating compressors. They are measured in terms of

velocity, inches per second (mm/s), in zero to peak values, band filtered from 10 to 250 Hz. Thevalues are guidelines only. In general, if vibration levels fall below those in TABLE 9-3, stress levelsare well below equipment fatigue stress limit.

4. Analyze levels exceeding TABLE 9-3 values to determine the cause. A spectral vibration analysisshould be performed by a qualified vibration specialist.

The following devices are acceptable for use on Ariel equipment.

Vibration SwitchAriel requires installation of an inertial or electronic vibration switch with the sensitive axis in the pistonrod direction. A minimum of 2 switches are recommended for six throw machines.

Velocity TransducersFor frames over 500 HP, Ariel recommends velocity transducers (or accelerometer transducersintegrated to a velocity measure) from a 10-250 Hz bandwidth, measured in peak or RMS converted topeak levels.Mount velocity transducers perpendicular to the crankshaft at the crankshaft centerline elevation. Asingle transducer on the drive end is adequate on 2-throw and 4-throw machines. Six-throw framesrequire one transducer on the drive end and one on the auxiliary end. Many Ariel frames now havemachined bosses for easy and solid connection. TABLE 9-3 guidelines can be applied to these readings.The packager may set these levels as initial alarms in the shop, but must reduce them to moreconservative protection levels after achieving normal operation.

Accelerometer TransducersAcceleration measurement on the frame or crosshead guides is sometimes a preferred method andacceptable as a secondary method of protection. Typically, acceleration is measured with a high samplerate over a wide bandwidth to quantify impact levels for protection. The many factors associated with thismeasurement (sensor resonance, sample rate, mounting, structure resonance), prohibit Ariel fromproviding predetermined amplitude limits. Set shutdown and alarms for these devices to a practical levelabove normal after normal operation is achieved. Given the variability of acceleration responses,


REV: 5/13 Page 9-7 of 8

Page 9-8 of 8 REV: 5/13

shutdown and alarms (as a percentage of normal operation) may vary with application. Thesemeasurements can also be sensitive to unloader and pocket activation.

Impact SensorsUse of crosshead guide impact sensors or accelerometers is optional. Impact sensors monitor and countpeak G levels over a set threshold for a certain number of revolutions, and report the count to the panel,usually in a 4-20mA current loop. They are typically mounted in the vertical direction on the crossheadguide or in the horizontal direction on the frame and are acceptable as a second level of protection.On high speed separable compressors, crosshead guides have a fairly high impact response in thevertical direction due to normal rod reversals. Sometimes a normal machine response can saturateimpact sensor electronics and cause nuisance alarms and shutdowns. Mount impact sensors on amachined surface. To mount on a guide, remove the lifting eyebolt and use the machined surface at thislocation. If a different location is preferred, drill, tap, and spot face the mounting hole. It is critical to drill thehole straight so the sensor sits flat on the machine.Mounting sensors on the frame in the horizontal direction at centerline elevation is also acceptable as asecond level of protection. Impact responses from looseness and debris transmit to the sensor effectivelyin this location. For frame mounting, use the machined frame bosses if possible. One impact sensor pereach pair of throws or in between throws offers adequate protection. Drill, tap, and spot face mountinghole. It is critical to drill the hole straight so the sensor sits flat on the machine.Impact sensors must be selected based on the intended operating speed of the compressor. Impactsensors require field tuning with a calibration tool. Consult manufacturer instructions for adjustment.Typical settings: time the reset level to capture approximately 16 revolutions at normal operating speed.Set the threshold to 1.25 to 3 times the normal baseline level depending on how unit load changes affectsensor response.

Section 10 - Package Assembly and RunTestingSeveral considerations need attention during assembly and run testing by the packager:1. When it is necessary to remove compressor covers, ensure dirt does not enter the machinery, and

re-install covers as soon as possible.

FIGURE 10-1 Hot/ColdSymbols

2. Do not sandblast the compressor without Ariel approval.3. Ensure all data and caution plates attached to the compressor or pro-

vided by Ariel are in place and heeded. Comply with standard safetypractices. Conspicuously and permanently mark compressor exteriorsurfaces, connected piping, and equipment which operates at tem-peratures above 158°F (70°C) or below 14°F (-10°C) with inter-national hot or cold surface symbols (see FIGURE 10-1). Otherwise,provide safety guards.

FIGURE 10-2 Control Panel CautionSticker

NOTE: Due to the hazardous nature of gas com-pression, Ariel requires a caution sticker (sup-plied by Ariel) affixed in plain sight on eachcompressor control panel. See FIGURE 10-2.

4. Perform activities such as the following under direc-tion of competent mechanics trained on Ariel com-pressors:• Cylinder installation • Data plate changes• Piston and piston • Piston end clearance

rod installation setting• Valve clearance • Valve re-springing

assembly installation

5. During shop testing, adhere to applicable items onthe Ariel Start Up Check List. Generally, the compressor valves are engineered for field conditionswhich can be different from shop conditions; prolonged running may damage valves.

6. Lifting eyebolts are not designed for high side loads; spreader bars may be necessary to preventbending the eyebolts.

7. Design and assemble the system to provide easy maintenance access for crankshaft, crosshead,valve, and piston removal.

Appendix A - ER-26Hold-down Bolting to Resist Shaking Forces andCouples in Reciprocating CompressorsRequirements1. To use the torques in the tables, the ultimate strength (Su) of the stud material must equal or exceed

100,000 psi (690 MPa); higher strength stud material is preferred. In all cases, torque the nuts tostress the stud to about 55% of the ultimate strength of the stud material; higher strength materialsrequire higher torques than shown in the tables. Material strength and torque are directly pro-portional. Example: for 120,000 psi (825 MPa) ultimate strength material: 120,000 ÷ 100,000 = 1.2 xmin. torque from table = required torque for given nut size. To use a different stud diameter, consultAriel for feasibility and torque.

2. Compressor frame foot hold-down studs and crosshead guide to support bolting should be as longas possible. Ariel recommends a minimum 12 to 1 length to diameter ratio.NOTE: Bolting long enough to reach only through the compressor foot and a deck plateor flange of an I-beam can loosen if not provided with engineered devices to maintain boltpre-load.

3. Tighten nuts as recommended above to maintain fastener pre-load during operation. Ariel also rec-ommends rolled threads and hardened spherical washers for hold down bolting to help compensatefor fastener to frame bolt surface angular misalignment.

4. Use grade 8 or 9 bolting to hold crosshead guides to supports.5. Re-preserve any fasteners subject to corrosion after installation.6. Follow lubrication guidelines and recommended procedures for torque accuracy in ER-63.

Appendix E - ER-25Preserving Ariel Reciprocating Compressors forStorageER-25 applies to Ariel reciprocating compressors stored for 12 months since last preservation. Theseprocedures should prevent corrosion inside an Ariel reciprocating compressor for 12 months if protec-tion is not compromised. If any deterioration occurs or the crankshaft is turned, re-preserve per ER-25.NOTE: ER-25 does not apply to non-lube compressor cylinders and distance pieces. UseER-34 to inspect and preserve non-lube cylinders and distance pieces.For new compressors to be stored longer than 12 months from the Ariel shipment date, seeER-10.5.1 “Warranty Administration Procedure” (see Appendix D, and apply for Deferred Start-upStatus to defer the Standard Warranty.

Preservation Materials and EquipmentUse the following or their equivalents:1. A contact rust preventative: Mobil Oil Mobilarma 247 or Cortec VpCI 322.2. A liquid vapor phase corrosion inhibitor (VpCI): Cortec VpCI 329 or VpCI 322. These products are

incompatible with polyglycol (PAG) synthetic oils. For PAG applications, consult Ariel. VpCI 329 andVpCI 322 are equivalent in strength and compatible with each other.

3. Cortec VpCI 369 corrosion inhibitor.4. Waterproof back, UV resistant tape: Shurtape PC667.5. Shipping covers and gaskets to seal cylinder suction and discharge openings.6. Wax impregnated cloth: MARVELPAK #12 JAN-B-121F, Type I Grade C, Class II. Available from

EDCO Supply (Brooklyn, New York).7. Priming pump if compressor does not have one.8. Tarps and tie down materials if storing compressor outdoors.

Preservation Procedure1. Inspect and preserve the compressor in a clean, dry environment. Remove the following:

• Top cover.• Crosshead guide covers.• Tape and wax impregnated cloth from drive stub.• Suction and discharge cylinder nozzle shipping covers.• One crank end suction valve from each cylinder.• One head end suction valve from each cylinder.• For packaged compressors, remove one discharge valve cap from each cylinder.

2. Inspect all compressor internal surfaces and cavities.a. Inspect for corrosion or standing water. If found, photograph affected areas and contact Ariel.b. Remove water contamination and corrosion prior to coating parts with rust preventative.c. Inspect for potential leak paths for water and air and seal them.d. Verify metal and plastic plugs are tight and replace damaged plugs.

Page E-2 of 4 REV: 5/13

e. Inspect exposed stainless steel tubing and verify metal tubing caps are tight.f. Inspect suction and discharge nozzle shipping covers and gaskets for damage.

3. Prime lube oil system with a fresh 50/50 mixture of compressor frame oil and rust preventative suchas Mobilarma 247 or Cortec VpCI 322, if compatible with frame oil.a. Pump rust preventative/oil mixture through the lube oil system. Introduce mixture upstream of the

oil filter. Verify oil visibly flows from all bearing positions and crossheads.b. Drain excess rust preventative/oil mixture from frame and guides. Lube oil piping should remain

filled with the rust preventative/oil mixture during the storage period.4. To prevent damage, perform Step 4 within 8 hours of Step 3. Thoroughly mix rust preventative

and VpCI before dispensing it. Use VpCI within 24 months of manufacture date. Spray all internalcompressor surfaces with a rust preventative such as Mobilarma 247 or Cortec VpCI 322, if com-patible with frame oil. Consult Ariel if rust preventative is incompatible with frame oil.a. Spray rust preventative inside frame, guide, and each compressor cylinder. Cover all internal sur-

faces including: unloaders, piston rod, valve pocket surfaces, retainers, valve caps, suction and dis-charge gas passages, valves, crosshead guides, and distance pieces.

b. Rotate crankshaft 180° and repeat Step a. Allow no noticeable accumulation of rust preventativein the bottom of treated cavities.

c. For KBB:V:Z:U models with o-ring seal top covers, lightly coat the top rail of the frame with CortecVpCI 369 or equivalent before installing top cover.

8. If your compressor is not shown in the tables above, contact Ariel for correct VpCl quantities.9. Add quantity of Cortec VpCI 329 or 322 to the following cavities:

• 1/2 ounce to the cylinder lube box sump via the fill plug.• 1 ounce to lube oil filter housings drained prior to shipment (not applicable to spin-on filters).• 1/2 ounce to lube oil pump discharge port.

10. VpCI corrosion inhibitors require protected cavities to remain sealed during storage. Open cavitiesdeplete VpCI concentration, rendering it ineffective. To prevent VpCI depletion, seal the compressoras follows:• Plug all openings including vents and breather connections. Verify plugs are tight.• Reassemble all covers and the valve assemblies and re-connect the pre-lube pump.• Seal cylinder suction and discharge nozzles with shipping covers and gaskets.• Verify proper installation of cylinder shipping covers and gaskets.• Replace damaged shipping flange covers or gaskets.• Hand-wrench tighten the shipping flange cover bolts in a criss-cross pattern.

11. Coat drive stub with rust preventative, wrap with wax impregnated cloth such as MARVELPAK #12,followed by waterproof backed tape such as Shurtape PC667.

12. Tape the clearance opening between the drive end dust seal cover and crankshaft to prevent anyexchange of air to the frame.

13. Ensure force feed pump stroke adjustment lock nuts are wrench tight and the priming stem is coveredwith wax impregnated cloth.

14. Ensure all vents, drains, and process piping are capped, plugged, or sealed to prevent air from enter-ing compressor.

15. Tag the compressor and guide/cylinder assemblies with a tag stating that the crankshaft should notbe turned and the date of the last compressor inspection and preservation. If the crankshaft is turnedfor any reason, re-preserve per ER-25.

StoragePrior to packaging, store the compressor in a clean, dry environment. If stored outdoors, protect it fromdirect contact with the elements. Never store a compressor with the mounting feet in direct contact withthe ground; protect them from corrosion.If the compressor is stored after packaging, protect all piping and bottles in the package in addition to thecompressor. Verify all openings in the package are sealed.

Commissioning Compressor to ServiceAt commissioning:1. Inspect all compressor internal surfaces and cavities. Inspect for corrosion or standing water. If found,

photograph affected areas and contact Ariel.2. Change the oil filter. There is no need to change oil, or if drained, to flush the frame prior to filling

with oil; the rust preventative will mix with the lube oil. For PAG synthetic oil applications, consult Ariel.3. Remove temporary covers, gaskets, plugs, tape, tags etc. that seal the compressor. Replace all con-

nections including vents and drains.4. Complete the Start-Up Check list (Appendix B or Appendix C).

Appendix F - ER-34Protection of Non-Lube Compressor Cylinders andDistance Pieces with VCI Powder for ShipmentThis procedure covers corrosion protection of non-lube compressor cylinders and distance piece cavitieswith Vapor Corrosion Inhibitor (VCI) powder for shipment. Vapor corrosion inhibitors are chemicalcompounds which react with oxygen to produce a vapor with anti-corrosion properties. The vaporsaturates an air space with negatively charged molecules which migrate to positively charged surfaces toform a protective mono-molecular film. This film creates a barrier to prevent oxygen and moisture fromcontacting metal surfaces. Parts removed from the vapors have no corrosion protection.Cylinders and distance piece cavities are treated at the factory for 6 months protection. Equipment notcommissioned in service within 6 months requires inspection and re-application of VCI. It is notnecessary to remove VCI powder before commissioning equipment.

Application1. Verify all interior cylinder surfaces are clean, oil free, and dry.2. Apply 7 grams (1/4 ounce) of VCI powder per cubic foot of cavity volume (245g/m3) for 6 months pro-

tection. TABLE F-1 lists quantities of VCI powder for Ariel cylinders and distance pieces. These quan-tities ensure adequate protection, regardless of cylinder or crosshead guide size.

3. Place VCI powder in an entrance (such as valve pockets and/or head end) and blow it into the cavitywith filtered, moisture-free, compressed air until all powder is finely and thoroughly dispersed or usea powder bellows. Treat distance piece cavities, both ends of cylinder, gas passages, valve areas,and unloaders.

4. After VCI application, immediately seal all openings to prevent any air exchange into the cylinder ordistance piece. Use Ariel supplied shipping covers, gaskets, and bolts to close openings. When acompressor cylinder ships separately, seal compressor rod/packing case area with waterproof clothtape.

5. For each compressor cylinder treated with VCI, mark quantity of VCI used and date applied in per-manent black ink on a temporary tag (Ariel part number A-5831). Attach tag to the cylinder.

Appendix H - ER-82Soft Foot and Top Plane Flatness Checks forProper Main Bearing Bore Alignment inReciprocating CompressorsMain bearing bore alignment is critical to main bearing and crankshaft life. Ariel manufactures the topcover mounting surface of a compressor frame in close tolerance to a flat plane, to the main bearingbores, and to the bottom of the compressor feet. The main bearing bores align when frame feet aresupported so the top cover mounting surface is flat and "in plane". Perform a soft foot check and topplane flatness measurement at these times:• Setting of a new compressor (pre and post grouting).• Commission of a compressor in the field.• Reinstallation of a compressor.• Relocation of a package.• Discovery of loose hold down fasteners.• Performance of recommended scheduled maintenance inspection every 6 months or 4000 hours.

With new unit installations, Ariel recommends checking and recording initial top plane flatness beforeshimming the guide feet and after initial rough coupling alignment. On compressors shippeddisassembled, perform the initial check before guide and cylinder assembly installation. Shim orotherwise adjust the height to bring the top cover mounting surface within the specified plane tolerance.Record subsequent readings after complete guide and cylinder installation, and again after any vesselinstallation and shimming. Re-adjust height if guide, cylinder, and/or vessel installation results in frametop rail measurements out of TABLE H-1 tolerances.JGB:V:Z:U and KBB:V:Z:U 4 and 6-throw frames require both a top plane flatness and soft foot checks.For all other frames, the soft foot check is required; the top plane flatness measurement is optional,except for the JGI, which requires none.Use the procedure below to properly install and periodically inspect compressor frames.1. To check soft foot, properly install and torque compressor frame hold down bolting. Loosen each

hold down bolt individually while checking the frame foot to skid deflection with a calibrated dial indi-cator. Correct any hold down position that deflects more than 0.002 inches (0.05 mm) whenreleased. Re-torque the hold down bolt and repeat on each frame-to-skid bolt. See ER-26 (AppendixA ) for proper frame foot and crosshead guide bolt size and torques.

2. Remove or reposition the top cover(s) and gasket(s) to expose the frame top cover mounting sur-face. Verify it is clean.NOTE: For KBZ:U frames only, the frame top rail has been coated with a light coat of Cor-tec VPCI 369 corrosion inhibitor or equivalent to protect the aluminum to cast iron joint. Ifthe top cover is removed, clean both the top rail and the top cover and re-coat the frametop rail with a light coat of the same compound. If VPCI 369 or equivalent is not available,use marine grade grease. Apply only a light coat of the corrosion inhibitor; do not allowexcess material to flow into the frame when the top cover is installed.

3. To check top plane flatness, use measurement equip-ment with a published accuracy of +0.001 inches(0.025 mm) over the distance required to measure theentire length of both frame rails. Measure the top sur-face of both sides of the frame rails at each anchor bolt(see FIGURE H-1), or between each pair of anchorbolts for frames with pairs of anchor bolts (see FIG-URE H-2). Readings between any two adjacent pointsmust be within 0.002 in. (0.05 mm). For proper align-ment, total accumulated out of plane flatness must bewithin TABLE H-1 tolerances.NOTE: If the unit will not be restarted imm-mediately, re-preserve the unit in a manner appropriate to the time duration until restart.

TABLE I-2 Maximum Angle from a Horizontal PlaneAllowed in Transient Motion without Dry Sump

a. The JGI frame, vertical non-balanced compressor, is not to be appliedoffshore.

b. Use dry sump as noted if compressor is subject to transient motion.

Compressors subject to transientmotion, roll, and yaw on board a ship ora floating platform may require a drysump (“dry” crankcase and separate oilreservoir). See the table for limits, whichare based on the angle where thecrankshaft/connecting rods will contactthe oil level causing foaming. The limitsassume that the running oil level ismaintained between one half and two-thirds the height of the sight glass whenthe frame is level.With a dry sump, drains are supplied ateach end of the compressor frame andan additional oil pump chain oiler isprovided by Ariel. The packager mustprovide a lube oil reservoir sized andlocated so that the oil pump has oilsuction regardless of the tilt of the shipor floating platform. An oil sump strainermust be installed in the pump suctionline at the outlet of the separate lube oil reservoir (unmounted strainer is provided by Ariel with a new drysump compressor). Refer to the Ariel outline drawings for connection sizes and locations.

Appendix I - ER-93 Packager Standards

Appendix J - ER-89.10Attachment of Wiring, Tubing, or Pipe Clamps toAriel Compressor CylindersAriel does not condone the practice of drilling and tapping holes to mount pipe, tubing, or instrumentclamps to any pressure containing component. Use of gas containment bolting to mount brackets orother structural attachments is not allowed. These practices can compromise the integrity of pressurecontaining components.

CAUTION: Do not drill holes in any pressure containing components for any reason.

An alternative method to attach clamps to compressor cylinders is to use an epoxy resin. Manyadhesives will likely work, but Ariel has tested some of them. After testing, Ariel can recommend Loctite331 or Loctite 332 applied to clean, unpainted metal.Follow all manufacturer instructions and recommendations to prepare the area for the adhesive. Theclamp and unpainted surface can be painted after the adhesive cures. With this method of clampattachment, there is no danger of compromising cylinder integrity.
