    2. SYSTEM OVERVIEW

    2.1 Description

    This Phase Dynamics analyzer measures the percentage of water in a flowinghydrocarbon liquid stream. The measurement technique is based on a principle knownas oscillator load pull. The system is designed with no moving parts and is calibratedfor the highest accuracy over a broad range of pressure, flow rate and temperature.

    The system consists of three components as shown in Figure 2.1(a);

    1) a measurement section,2) an electronics unit, and3) a system cable connecting the two.

    The measurement section, shown in Figure 2.1(b), is an assembly of;7

    1) a pipe section,2) a temperature sensor, and3) a microwave oscillator module mounted in a protective enclosure.

    Figure 2: Measurement Section

    The electronics unit is an application-specific computer which provides a variety offunctions;

    1) liquid crystal display,2) four switches for operator interface,3) input voltage regulation,4) DC voltage for oscillator module, and5) all input/output functions necessary for proper operation.

    The system cable provides the "link" over which the electronics unit provides thenecessary voltages to the oscillator module. The oscillator also sends the appropriatesignals of frequency, temperature, and reflected power to the computer for calculation ofwater content.

    2.2 Typical operation

    Under normal conditions, the analyzer's operating sequence may be described by thefollowing chain of events.

    The input voltage is converted to the necessary DC voltages. At turn-on, the electronicsunit performs a set of self-diagnostic tests to assure functionality. The power supplyprovides 15 and 30 VDC to the oscillator module: 15 V to the oscillator and 30 V to aheater which maintains the oscillator at 160F. This eliminates any frequency drift dueto circuit temperature changes which could result in errors in water content. A 5 Vsupply operates the electronics unit's digital circuitry.

    The fluids flowing through the measurement section act on the unbuffered microwaveoscillator to force a change in its natural frequency of oscillation.

    The temperature sensor is inserted directly into the liquid stream through the pipe wallof the saddle nearer the microwave oscillator. The sensor's wires, enclosed in stainlesssteel tubing, transmit this signal to the oscillator module and then on to the electronicsunit.

    The oscillator's reflected power signal is measured. This information is used todetermine the phase of the emulsion - water in oil or oil in water. Inside the oscillatormodule, frequency counting and division circuits lower the microwave signal to afrequency which can be transmitted over the system cable's shielded twisted pair.

    The frequency, temperature, and reflected power signals are transmitted via the systemcable from the oscillator module to the electronics unit. These signals are routed to themicroprocessor where a salinity and temperature compensated water content iscalculated from the factory-derived coefficients.

    Simultaneously, a signal proportional to water content appears at the analog looptransmitter and the LCD provides an instantaneous readout of the calculated watercontent and measured temperature.

    The frequency measurement cycle is repeated approximately once per second to

    provide an instantaneous, continuous, and real-time measurement of water content.

    While the continuous measurement of water content is going on, the electronics unitperiodically executes self-diagnostic checks to determine if any functional aspect of thesystem is in error. Occasionally, the LCD will show the various tests being checked andpassed (Checking EPROM, Checking SRAM, Checking INTRAM, etc.)., Theseself-diagnostics tests are completed "in the background" and in no way affect thefundamental measurement or calculation of water content.

    If at any time any system error is detected, two things happen:

    1) the LCD exhibits the specific ERROR message, and2) the ERROR relay contact closes.

    The four switches labeled "MENU", "SELECT", "VALUE", and "ENTER" allow theoperator to access a variety of parameters and coefficients. The value for theseparameters may be changed and entered into the operating memory of the system toprovide proper outputs and accurate water content measurements.

    2.3 Principal of operation (oscillator load pull)

    Phase Dynamics' analyzers achieve superior performance by utilizing microwave

    oscillator load pull. Load pull is the term given to describe the frequency change of anunbuffered oscillator as its output load varies. Circuit components and the external loadimpedance determine an unbuffered oscillator's frequency. The permittivity of thematerials in the measurement section, through which the microwaves propagate,determine the output load.

    The measurement section consists of a small solid rod mounted inside a larger diameterpipe, as shown in Figure 2.3(a). One end of the rod is connected to an unbufferedoscillator and the other end connects to the center of a welded "shorting" plug. Thecenter rod is covered by a hard plastic sheath to prevent direct contact between themetal rod and conductive water-oil emulsions. Electrically this pipe, rod, and sheath

    combination is a coaxial transmission line, terminating into a short circuit. The fluidsflow through the measurement section via the connections that mount perpendicular tothe run section, one at each end. The microwave signal travels the length of the pipetwice; down the pipe from the oscillator, then reflects at the shorting plug and traversesback to the oscillator module.

    Figure 3: Measurement Section and Center Rod/Sheath Assembly

    The permittivity of the emulsion changes as the percentage of water in the total fluidchanges. The permittivity of the emulsion is comprised of two parts - the dielectricconstant and the loss. The relative dielectric constant of oil is 2.2 and of water is about70. The loss is determined primarily by the salt content of the water. Accuratemeasurement of the water salinity and proper input to the electronics unit is essential forbest accuracy of the Phase Dynamics Full Range Water-Hydrocarbon Analyzer.

    In summary, the permittivity of the oil-water emulsion in the measurement sectionprovides a complex impedance, or load. The load acts directly upon the unbufferedoscillator to force a predictable, repeatable, and precise change in frequency. Thisfrequency is proportional to the water content of the emulsion. Temperature and lossalso affect the frequency; both are used for compensation to calculate the correct watercontent. The microprocessor uses the measured frequency to calculate and update thewater content each second.

    2.4 Oil and water continuous emulsions

    Oil-water emulsions may exist in two phase states. The emulsion may be described aswater drops suspended in a continuous medium of oil (oil continuous or oil external) oroil drops suspended in a continuous medium of water (water continuous or waterexternal). The phase of the emulsion is determined by a number of factors includingwater content, temperature, pressure, salinity, crude API, presence of emulsifiers, etc.

    Furthermore, there is a wide range of water contents (about 40-90%) which may exist ineither phase. The system must first determine the correct phase before any accuratewater content data may be calculated.

    The oscillator module of each system contains two separate circuits, each operating at

    different frequencies. Each circuit is optimized for best pulling for a particular phase -one oscillator for oil continuous emulsions and the other for water continuous.

    At times, two emulsions, one oil and one water continuous, with significantly differentwater contents, may give the same measured frequency of the load pull system. Asecond parameter must be measured to distinguish the phase.

    The measured parameter to distinguish emulsion phase state is the oscillator's reflectedpower. Water continuous emulsions yield much lower reflected power levels than oilcontinuous - the energy is dissipated through the conductive water. Very little energy isreflected back to the oscillator module, as shown in Figure 2.4(a).

    Oil continuous emulsions are much less lossy than water continuous. For this case, themicrowave energy travels down the measurement pipe section and back with very littleloss in the emulsion itself; the reflected power level is higher than for water continuousemulsions, as shown in Figure 2.4(a).

    In summary, the system monitors the reflected power level to determine the phase. Oilcontinuous emulsions exhibit high power levels and water continuous emulsions givelow power levels. Once the phase is determined, the system switches to theappropriate oscillator for frequency measurement and determination of water content.

    Figure 4 Reflected Power Levels for Oil-Water Emulsions

    2.5 Effect of dissolved salts

    For water continuous emulsions, dissolved salts significantly affect the load(measurement section plus liquids) as seen by the microwave oscillator. For oilcontinuous emulsions, dissolved salts have little or no effect. As shown in Figure 2.5(a),one measured frequency corresponds to a range of water contents in the watercontinuous phase, depending on the concentration of dissolved salts.

    Each Phase Dynamics system includes compensation for effects due to dissolved salts.Accurate measurement and manual entry of dissolved salts is required for accuratewater content measurements.

    IMPORTANT NOTE ABOUT DISSOLVED SALTS :For optimum performance, it isIMPERATIVE that the Salinity Calibration routine be executed properly.

    3. INSTALLATION

    3.1 Pre-installation notes

    The materials of construction for Phase Dynamics' analyzer are capable of withstandinga wide variety of harsh environments. The pipe section itself is made of standard pipeand flanges used on a routine basis for the industry serviced. The microwave oscillatoris assembled in a protective housing which is then completely enclosed in anexplosion-proof junction box, provided with a screw-on cap for access. The individualprinted wiring boards of the electronics unit are mounted on a protective aluminumchassis. This chassis is then mounted and protected in either a cast-aluminumexplosion-proof enclosure (rated NEMA 4,7, and 9) or a fiberglass enclosure (ratedNEMA 4X) which is raintight, dustproof, and corrosion resistant. A rack mount versionis available as an option.

    The ambient operating temperature of the electronics unit is specified as 32to 130F.For proper operation, the electronics should not be cooled below 32F. The electronicsenclosure should be mounted to avoid exposure to prevailing winds in freezing climates.An optional heater circuit is available for continuous cold weather operation.Conversely, the enclosure should be mounted in a shaded area to avoid direct sunlightfor geographic regions where ambient temperatures are above 100F. Both theexplosion-proof and fiberglass enclosures are rated as watertight.

    The measurement section is rated for AMBIENT temperatures from -10to 130F

    (maximum FLUID temperature 160F). The oscillator module contains a miniatureheater circuit to maintain the critical circuit at 160F. The junction box protecting the

    oscillator module is provided with an O-ring for the screw-on cap and forms a watertightseal.

    3.2 Mounting considerations

    3.2.1 Measurement section

    The preferred orientation of the measurement section is vertical with the oscillator endup. Fluid flow comes into the connection closest to the oscillator and exits the other port.

    For best results, liquid flow in the measurement section should be turbulent to keep theoil/water mixed and to "flush" any gas or water accumulation in the pipe section.

    The recommended range of flow rate for optimum performance is 1 to 10 feet persecond fluid velocity (about 700 to 7,000 barrels per day for a 3-inch measurementsection). Lower flow rates may result in oil-water separation and measurement errors.Higher flow rates may result in a large pressure drop and the possibility of cavitation orerosion.

    If free gas is present in the liquid stream, the output should be mounted higher than theinput to allow the gas to escape the pipe section. Gas tends to decrease the calculated

    water content.

    For slip-stream applications, verify that the fluids flowing through the measurementsection precisely represent the fluids of the main stream.

    While the above guidelines are the preferred orientation, field experience has verifiedthe accurate measurement of water content for a variety of mounting schemes,including vertical, either end up, horizontal, flanges up or down, and the measurementsection "on its side". The most important points to keep in mind are:

    l) well-mixed water and oil in the measurement section,

    2) turbulent flow,3) zero gas content (or, at least, long term constant gas content), and4) representative emulsions in slip-streams.

    3.2.2 Electronics unit

    The viewing angle of the LCD, located on the front control panel, is adjustable fromperpendicular to 30 degrees above perpendicular. As such, the enclosure should bemounted about five feet above the ground. Ease of viewing, convenience of wiring, andsimplicity of operation are the only restrictions in orientation of the electronicsenclosure.

    3.3 Installation drawings

    Detailed installation drawings are included with each system to assist in preparation ofmounting and installation. Refer to the appropriate drawings for installation of yourparticular system.

    3.4 Basic electrical hook-up

    CAUTIONThe electronics unit is mounted relatively close to the measurement pipesection. A system cable of 20 feet is supplied to connect the two.

    4. GENERAL OPERATION AND INITIAL START-UP

    Four modes of operation are available with this Phase Dynamics analyzer; Normal,

    Supervisor, Technician, and User-defined Mode. Each mode provides certain featuresand parameters to the user for change or modification. The two position DIP switchlocated at the edge of the microprocessor board determines the particular mode inwhich the system is currently operating. The location of the DIP switch is as shown inFigure 4(a). The two white switches are clearly marked on the body of the switch, "1"and "2".

    Figure 8: Location of Two-Position Dip Switch

  • 8/9/2019 Manual Full Range Analyzer Standard

    34/89

    PHASE DYNAMICS, INC.

    24

    Table 4(1) below defines the position of the two switches for the four available modes ofoperation:

    Mode of Operation Switch 1 Location Switch 2 Location

    Normal right right

    Supervisor right left

    User-defined left right

    Technician left left

    Table 4(1). Accessing the Four Modes of Operation.

    The Phase Dynamics load-pull system may be operated safely and properly for anylength of time in any of the four modes. The particular mode of operation is chosen bythe user and is typically determined by the specific conditions for a given installation.

    4.1 User interface switches and functions

    The four user interface switches are labeled "MENU", "SELECT", "VALUE", and"ENTER". These control keys allow the user to interact with the electronics unit tocomplete a variety of tasks including scaling of outputs, adjusting calibration factors,and modifying factory coefficients.

    The MENU key scrolls through the list of MENU items. Each time MENU is pressed anew item is displayed until all items have been shown and the normal display returns.To return to the top of the MENU list, simply press and hold MENU for approximatelytwo seconds.

    The SELECT and VALUE keys change the value of the selected menu item. PressingSELECT moves a blinking cursor to the digit of the parameter to be changed. TheVALUE key increments the digit's value by one each time VALUE is pushed. Once thedigit's value is nine, the next time VALUE is pushed, the digit's value becomes zero andincrements to nine again.

    The ENTER key stores a changed value for the selected menu item. Once ENTER hasbeen pushed, the new value is stored and THE OLD VALUE IS LOST.

    NOTE: The ENTER button must be pushed to store a new parameter's value, otherwisethe desired new value is ignored and the last valid value is retained.

    Each time the ENTER button is pushed, the new value is stored and the next menu itemis displayed.

    Pressing two or more of the switches simultaneously or pressing any key out ofsequence, will result in a "Switch Error" message on the LCD. All switches must be

    released to allow the system to recover to normal operation; no changes were entered.

    4.2 Initial start-up

    After installation, verify that switch 1 and 2 are to the right to access the Normal Mode.Apply power and observe the LCD. The following series of tests is executed at power onand any errors will be reported;

    1) POWER,2) EPROM,3) EEPROM,

    4) INTRAM,5) SRAM, and6) Analog Input Calibration.

    Note any ERROR message and refer to the comprehensive list of ERROR messagesfound in Section 7.

    Once the self tests are completed, the display will show the calculated water contentand measured temperature, as shown in Figure 4.2(a). The emulsion's continuousphase (oil or water) is also displayed. For water continuous emulsions, the watersalinity is displayed. Throughout the Normal Mode of operation, the self-diagnostic

    testing will continue and messages sent to the LCD. This testing is completed "in thebackground" and in no way interferes with or interrupts the basic measurement of watercontent. If a system error is detected the appropriate ERROR message will bedisplayed; hardware related system errors cause the error relay's contacts to close.

    Figure 4.2(a) shows the Normal Mode display for the as-delivered factory defaultcondition with Flow Input Disabled (no fluid volumes shown). The Normal Mode displayfor Flow Input Enabled will look slightly different, as shown in Figure 4.2(b). For thiscondition, the selected fluid totals are displayed, in addition to the water content,emulsion's phase, and measured temperature. For water continuous emulsions, thewater salinity is displayed.

    5. MODES OF OPERATION

    The four modes of operation include Normal, Supervisor, Technician, and User-definedModes. Each of these modes provides a different set of parameters and features whichmay be helpful to the user.

    The Normal Mode contains a list of the most common and useful MENU items forproper operation of the system. This is the mode the instrument is in when deliveredfrom the factory.

    The Supervisor Mode provides two functions. All stream specific calibration constantsmay be reset to the factory default values. Each stream is identified by the streamidentification number (stream 01 is factory default). And, the MENU items to appear inthe User-defined Mode are selected by the user.

    The User-defined Mode is a mode containing a subset of Normal Mode MENU itemswhich have been identified by the system supervisor. This may be helpful if the userwould like the ability to change or modify a specific set of coefficients or values withouthaving to step through the entire list of MENU items of the Normal Mode. For example,the User-defined Mode may contain only the stream specific calibration values(including the associated four items for each) and the Salinity Calibration Routine. Theuser-defined MENU items for this mode are defined while in the Supervisor Mode.

    The Technician Mode is a universal mode; the values of all parameters and coefficientsmay be displayed, one item at a time. The values for all field-selectable parameters

    may be changed while in the Technician Mode. However, some coefficients used bythe load-pull system may not be changed by the user (i.e. O-constants, W-constants,and Delta Salt); these coefficients are read-only types. The Technician Mode alsoincludes the capability to reset all coefficients to their factory default values.

    5.1 Normal Mode

    5.1.1 Accessing the Normal Mode

    The Normal Mode is accessed when both switches 1 and 2 of the dual DIP switch,located at the edge of the microprocessor board, are moved to the right.

    CAUTIONSteps should be taken to eliminate any static charges on your hands or tools soas not to damage any surrounding electrical components when changing theswitch positions. Also, since both switches are fairly close to each other, care

    should be taken to open or close only the necessary switch.

    29

    5.1.2 MENU items for the Normal Mode

    For each MENU item that is field selectable, the LCD will display the UPPER and

    LOWER limits which are allowed for that item. If a user-selected value which is out ofrange is "ENTER"-ed, the display will prompt "Value Out of Range" and will return theitem's value to the last valid value.

    To advance to the next MENU item without changing its value simply press MENU.

    To return to the Normal Mode Display (and the top of the list of MENU items), simplypress and hold MENU for approximately two seconds.

    Following are the MENU items in the order which they are accessed in the NormalMode. Included is a brief description of the item and the factory-supplied default value

    (shown in [ ]).

    Stream xx [01]; Up to 50 stream specific sets of calibration data may bestored in the operating memory of the system. The next fourMENU items (Salinity, Water Adj., Oil Adj., and Alarm Point)correspond to the displayed stream number.

    SELECT and VALUE change the stream identificationnumber. ENTER executes the selected stream.

    Stream xx

    Salinity [2.00%]; The current value of water salinity for the displayed streamnumber. The water salinity value may be input manuallywhile in the Normal Mode. This value may also be changedin the Technician Mode.

    SELECT and VALUE change the value. ENTER stores thedesired value.

    Stream xxWater Adj. [0.0%]; Water Adjust; A calibration factor (+ or -) may be added to

    the WATER CONTINUOUS water content to compensate for

    the difference between field and factory conditions, for thedisplayed stream number, i.e.,

    Displayed water content =Calculated water content + Water Adj.

    SELECT and VALUE change the value. ENTER stores thedesired value.

  • 8/9/2019 Manual Full Range Analyzer Standard

    40/89

    PHASE DYNAMICS, INC.

    The analog loop output current also includes the Water Adj.value, as does the RS-422 value for water content.

    Stream xxOil Adj. [0.0%]; Oil Adjust; A calibration factor (+ or -) may be added to the

    OIL CONTINUOUS water content to compensate for thedifference between field and factory conditions, for thedisplayed stream number, i.e.,

    Displayed water content =Calculated water content + Oil Adj.

    SELECT and VALUE change the value. ENTER stores thedesired value.

    The analog loop output current also includes the Oil Adj.value, as does the RS-422 value for water content.

    Stream xxAlarm Point [100.0%]; Alarm set point; Water content values greater than (or less

    than) this value cause the alarm relay contacts to close.However, the water content value must have been greaterthan (or less than) the set point for a period of timedetermined by Time Delay.

    Once the Set Point has been entered, the system will ask"Greater than" or "Less than" the Set Point value. SELECTtoggles between the two conditions, ENTER stores thechosen direction. Thus, the alarm condition will occur for ameasured water content value above or below a given value,as determined by the user.

    Time Delay [0 sec]; The amount of time that the water content value must be above (orbelow) the Alarm Set Point before closing (or opening) thealarm relay contacts (sometimes referred to as "dead band").

    SELECT and VALUE change the value. ENTER stores thedesired value.

    Alternate Display[Normal Mode Display]; Press SELECT to toggle between Normal Mode display and

    the Alternate Display, which is similar to the TechnicianMode display. ENTER selects the desired display.

    Use of the Alternate Display is helpful when recording themeasured values of oscillator frequency, reflected power,and temperature during instrument setup or troubleshooting.

    After five minutes, the system will automatically return to theNormal Mode display.

    Flow Input [Disabled]; Flowmeter input option. The SELECT switch togglesbetween Flow Input Disabled, Pulse Flow Input, 0-20 mAFlow Input, and 4-20 mA Flow Input. Press ENTER toexecute the desired Flow Input.

    If any of the three flow inputs are ENTER-ed, the user will beasked to define four items; units of volume, minimum flowrate, maximum flow rate, and displayed volumes.

    To choose the UNIT of volume, press SELECT to scrollthrough the choices of barrels, gallons, or liters. Press

    ENTER to execute the desired UNIT.

    For Pulse Flow Input selected, the default value is 15,000pulses; this represents one UNIT of total fluid [15,000pulses/UNIT]. Zero pulses represents zero flow rate.For 0-20 mA or 4-20 mA Flow Input selected, the default flowrate for minimum current input, 0 or 4 mA, is zero [0UNITs/day]. The default flow rate for maximum current input,20 mA, is 5,000 UNITs/day [5,000 UNITs/day].

    The SELECT and VALUE buttons change the default values

    for minimum and maximum flow rates. ENTER stores thedesired values.

    Next, the user may choose the desired fluid volumes to bedisplayed on the LCD. All volumes are displayed are in theuser-selectable UNIT of volume.

    5.2.1 Accessing the Supervisor Mode

  • 8/9/2019 Manual Full Range Analyzer Standard

    43/89

    Water-Hydrocarbon Analyzer

    33

    The Supervisor Mode is accessed when switch 1 of the dual DIP switch, located at theedge of the microprocessor board, is moved to the right and switch 2 is moved to the

    left.

    5.2.2 Supervisor Mode display

    The initial display for the Supervisor Mode is the same as that of the Normal Mode.Two displays are available, one for Flow Input Disabled and one for Flow Input Enabled.To proceed from the initial display to the definition of MENU items for the User-definedMode, press MENU.

    5.2.3 Resetting stream specific coefficients

    The first MENU item of the Supervisor Mode allows the user to reset ALL of the streamspecific coefficients to the factory default values. The coefficients which are resetinclude (factory defaults are shown in []);

    1) Salinity [2.00%],2) Water Adj. [0.0%],3) Oil Adj. [0.0%], and4) Alarm Point [100.0%].

    Additionally, the current stream number is set to 01.

    Please note that when these coefficients are reset, ALL FIELD DERIVED VALUESWHICH ARE STREAM SPECIFIC ARE ERASED AND LOST!!!

    CAUTIONSteps should be taken to eliminate any static charges on your hands or tools soas not to damage any surrounding electrical components when changing theswitch positions. Also, since both switches are fairly close to each other, care

    should be taken to open or close only the necessary switch.

  • 8/9/2019 Manual Full Range Analyzer Standard

    44/89

    PHASE DYNAMICS, INC.

    34

    All stream specific coefficients are reset as follows;

    1) Access Supervisor Mode (switch 1 open, switch 2 closed),2) View LCD,3) Display prompts "Press ENTER to reset to stream defaults",4) Press ENTER if desired (if not, press MENU),5) Display prompts "Press SELECT if you are sure", (if not, press MENU to

    move to next item), and,6) Press SELECT if desired,7) Display confirms "Stream Defaults Restored", and8) Returns to Supervisor Mode display.

    5.2.4 Defining the MENU items for the User-defined Mode

    The Supervisor Mode is used to define the MENU items which are available in theUser-defined Mode. To proceed to this task, press MENU twice from the SupervisorMode display (bypass the "Reset stream values" item). The display includes four linesof text;

    Line 1 - will show "Defining User Mode",Line 2 - will show "Present status of",Line 3 - will show the current MENU item under consideration, andLine 4 - will show "is: ENABLED" or "is: DISABLED".

    Defining the MENU items for the User-defined Mode is straightforward. The display will

    show each MENU item of the Normal Mode, one at a time. For each item, the systemwill ask the user which items are to be included in the User-defined Mode. Once"ENABLED", only those chosen MENU items are available for access and change whenin the User-defined Mode.

    The User-defined Mode may be redefined at any convenient time by accessing theSupervisor Mode and selecting from the complete list of MENU items. At all times theSupervisor Mode shows the current status of each MENU item of the User-definedMode.

    For each MENU item, the display will prompt;

    1) Present status is ENABLED, or2) Present status is DISABLED.

    SELECT toggles between the choice of ENABLED or DISABLED for the specific itembeing displayed; ENTER will direct the system to execute the desired choice and moveto the next MENU item.

    6. CALIBRATION PROCEDURE

    6.1 Factory calibration

    Each Phase Dynamics analyzer is carefully calibrated at the factory prior to delivery. Aprecisely controlled flow loop is used to determine the unit's frequency response as afunction of water content. This response determines the coefficients used to computewater content from the measured frequency. For water external emulsions, dissolvedsalts affect the analyzer's response. The instrument is factory calibrated over a widerange of dissolved salts using sodium chloride (NaCl); in the field, dissolved salts aredetermined by several dissolved solid species including barium, bicarbonate, calcium,carbonate, chloride, iron, magnesium, potassium, sodium, sulfate, etc. Also, thecalibration flow loop is used to measure the effects of temperature on the system so thattemperature compensation of the measured water content is included. An appendixincludes a comparison of various laboratory methods for the determination of water incrude oil.

    6.2 Salinity calibration

    Since the load pull system is sensitive to dissolved salts for water continuousemulsions, it is very important to field calibrate for water salinity at any appropriate time.These times may include new well, new product, new formation, change in season,change in background of water, process change resulting in a different water salinity,etc.

    IMPORTANT NOTE ABOUT DISSOLVED SALTS :For optimum performance, it isIMPERATIVE that the salinity calibration routine be executed properly.

    The salinity calibration routine is accessed through the Normal or Technician Modes.The User-defined Mode may also be defined to include salinity calibration.

    To calibrate for the current water salinity, pump through (or pour into) the measurementsection a water sample representative of the produced water under test. It isrecommended to complete the salinity calibration for the highest water contentattainable. At a minimum, salinity calibration must be executed for water continuousemulsions.

    The Salinity Calibration routine is used to compensate for the difference between thesalinity compositions of the field water and the factory calibration water. The salinity ofthe water used during the factory calibration is determined by the amount of puresodium chloride (NaCl) in water. In the field, the apparent salinity of the water isdetermined by several dissolved solid species including barium, bicarbonate, calcium,carbonate, chloride, iron, magnesium, potassium, sodium, sulfate, etc. The SalinityCalibration should be completed the first time a new stream ID is defined or when the

    55/89

    Water-Hydrocarbon Analyzer

    45

    composition of the field salinity has changed.

    This routine calculates the Salinity based on the sodium chloride concentrations used in

    the factory calibration.

    Each and every stream should be initially calibrated using the Salinity Calibrationroutine. Each stream ID will include a corresponding Salinity value.

    The procedure for the Salinity Calibration and the action required for each step is givenbelow;

    DISPLAY ACTION

    8. THEORY OF OPERATION

    The following sections describe, in detail, the specific operation of the Phase Dynamics

    load-pull system and how it is used to measure water content. The sections areseparated into two main parts - one describing the behavior of the instrument for oilcontinuous emulsions and one for water continuous emulsions.

    8.1 Detailed description for oil continuous emulsions

    The load-pull system relates a measured oscillator frequency to a water content. For oilemulsions, the system is factory calibrated by injecting salt water into a flowing volumeof oil. Coefficients are derived to relate the measured frequency to the water content fora given temperature. The water content for oil continuous emulsions at a constanttemperature is calculated as follows;

    Water (Oil Phase) = O3 * (Freq + Oil Idx)3

    + O2 * (Freq + Oil Idx)2

    + O1 * (Freq + Oil Idx)+ O0+ Oil Adj.,
