Traditionally, cleaning processes used in the manufacture of original equipment and in the maintenance of this equipment have relied heavily upon the use of

ACTRE L” HYDROCARBON CLEAN ERS FROM

chlorinated hydrocarbon or chloro- fluorocarbon (CFC) solvents. While these solvents are highly effective in removing greases, oils and particles from substrates like metals, plastic and glass, they also have environmental and health concerns. Two of the most commonly used solvents, 1 , I , I 4richloroethane (1 11 -TCA) and trichlorotrifluoroethane (CFC-113) will soon be phased out completely under the 1990 Clean Air Act Amendments.

Exxon Chemical Company’s new ACTREL@ “L” cleaners were specifically developed as economic replacements for chlorinated and CFC solvents in metal and precision cleaning for OEM and maintenance applications. They are used “as is” in non-aqueous liquid-phase cleaning processes such as immersion, flushing or wiping.

Actrel cleaners are based on aliphatic hydrocarbons, such as synthetically produced branched paraffins, cyclo- paraffins or linear paraffins, which are blended, as required, with suitable oxygenated hydrocarbons. They have been manufactured to meet the stringent performance, environmental and health requirements of modern industrial cleaning.

EmON CHEMICAL

Actrel cleaners provide good cleaning power, low corrosivity, good wetting and penetration, and spotless drying.

Given the wide variety of soils, operating requirements and substrates, Exxon Chemical offers a family of cleaning agents to better meet your diverse needs. The family differs in two key properties: flash point and dry time.

The flash points of Actrel cleaners are all tightly controlled. Those with flash points of 10Oo-199" F (37.8"-92.7" C) have a Department of Transportation (DOT) classification of "combustible," while those with flash points 2200" F (293.3" C) are not regulated by DOT. The DOT classification affects transportation and storage requirements. The flash point also determines the maximum safe operating temperature of the cleaner, as described elsewhere in this brochure.

Most Actrel cleaners have flash points above 140" F (60" C). Waste streams with flash points greater than 140" F (60" C) and meeting no other RCRA category may be classified as industrial (non-hazardous) waste and benefit from lower disposal costs.

These cleaners are all less volatile than halogenated solvents currently in use. As a result, the dry times are slower. At ambient temperature, the drying time of the lowest flash point cleaner is from 1 to 10 minutes depending on the shape of the parts and the drying method used (ambient, forced-air, wiping, etc.).

Typical of hydrocarbons, the higher flash point cleaners are less volatile and will have longer dry times than the lower flash point cleaners. Drying times for the higher flash point cleaners can be reduced by using heated forced-air drying or by rinsing with a lower flash product and drying under ambient conditions.

Exxon Chemical has a worldwide network of technical experts and cleaning labs that are equipped to determine the optimum fluid for different applications. We have worked with many customers to select the best cleaner for their applications, and to develop and evaluate new fluids being considered for metal cleaning. A wide array of soils, parts and cleaning techniques has been studied. A summary of some of these test results is presented in "Actrel Cleaners - Recommended Grades for Cleaning Applications. "

Sample discoloration & softening ** Sample discoloring & cracking

Laboratory data, backed by actual testing of customer machinery and parts, confirms that Actrel cleaners generally perform AS WELL, OR BElTER than their chlorinated solvent counterparts for several reasons:

In metal cleaning, the principal types of grimes to be removed, (lubricants, metal working fluids and greases) are primarily composed of hydrocarbon chemistries. The rule in cleaning “like dissolves like” definitely applies, resulting in a high percentage of grime solubilization.

Because Actrel cleaners have very low surface tensions, they deliver good wetting, penetration and subsequent cleaning of tight fitting, or constricted areas. This is particularly important for fine, delicate tools and parts.

The low non-volatile residue and metals content of Actrel cleaners results in clean, residue-free parts and machinery after drying (see Table).

LOW CORROSIVITY AND NO FLASH

DISSOLVING POWER

PENETRATION POWER

LOW RESIDUE

RUSTING Because they are non-aqueous, neutral, and contain extremely low levels of reactive components, Actrel cleaners exhibit very low corrosivity to common metals. They will not induce flash rusting‘ as with alkaline cleaners. And they are suitable for cleaning sensitive non- ferrous metals such as aluminum, and alloys containing magnesium, lithium, zinc and titanium. A summary of the results from two testing laboratories is presented in “Actrel Cleaners - Metal Compatibility Data.”

GOOD COMPATIBILITY WITH ELASTOMERS AND PLASTICS Actrel cleaners are compatible with many plastics and elastomers, and in general, produce less swelling and damage than 1,1,1 Trichloroethane. Some compatibility data is presented in the Table. Since compatibility will vary depending on material composition, it is advisable to pretest critical plastics and rubber components prior to use.

SAFE FOR THE ENVIRONMENT NO OZONE DEPLETION POTENTIAL Actrel cleaners have no ozone depletion potential and thus, unlike 11 1 -TCA and CFC-113, are not subject to phase-out under the 1990 Clean Air Act Amendments (CAA).

Also, parts cleaned with Actrel Cleaners do not have to be labeled with an ozone depletion warning label in accordance with Section 61 1 of the CAA.

SUBMllTED TO EPA (SNAP) PROGRAM Section 612 of the CAA requires that the EPA publish a list of prohibited sub- stances and a list of corresponding safe alternatives to ozone depleting chemicals such as CFC-113 and 1 1 1 -TCA. This program is commonly referred to as the Significant New Alternatives Program (SNAP).

Physical properties, performance data in cleaning systems, environmental impact data and toxicity information on Actrel cleaners were submitted to the EPA in December, 1991, with follow-up infor- mation in March, 1992. As of this writing, it is anticipated that the EPA will identify them as safe alternatives to CFC-113 and 11 1 -TCA in cleaning.

NO SARA SECTION 313 REPORTABLES Section 313, Superfund Amendments and Reorganization Act (SARA) man- dates that a facility must report to the EPA usage and releases of specific “toxic chemicals”. All of the common chlorinated solvents used in metal cleaning are subject to reporting under SARA. Actrel cleaners do not contain Section 31 3 ‘Yoxic chemicals” and therefore are not reportable.

CONTAINS NO HAZARDOUS AIR POLLUTANTS As defined in the 1990 Clean Air Act Amendments, Actrel cleaners are not Hazardous Air Pollutants (HAPs). Thus, Title Ill provisions which require the use of Maximum Available Control Technol- ogy, if HAPs emissions exceed certain limits, are not applicable.

COMPATIBLE WITH MODERN VOC REGULATIONS AND CONTROL TECHNOLOGIES The release of volatile organic compounds (VOC) into the atmosphere is being more tightly regulated to reduce air pollution in non-attainment areas. Definitions of VOC and regulations for VOC control vary between jurisdictions and applications.

As further described in "Actrel Cleaners and VOC Regulations," the Actrel family has the following benefits:

Regulatory Status Actrel cleaners are not photochemically reactive solvents as defined by most state regulations, such as California South Coast District Rule 102 (Old Rule 66).

Some Actrel cleaners with vapor pressures below certain limits, typically 0.1 -1 mm Hg @ standard conditions, may have "VOC exempt" status.

Emission Control Technologies Due to the low vapor pressure of Actrel cleaners, emissions from cleaning and drying operations can readily be controlled to low levels. The Control Technologies specified in most state and federal regulations currently require that cleaning machines have covers, internal drainage provisions and freeboard ratios above certain minimums.

If VOC recovery from drying air is required, standard technologies, such as condensation, carbon adsorption, or incineration, are suitable.

LIMITED CONTACT WITH WATER Because the Actrel cleaning system is non-aqueous, these cleaners will not routinely come into contact with water. The main exception might be during accidental spills. These cleaners have very low water solubility, and are also less dense than water. Thus, during a release to water, they will remain on the surface and largely evaporate over a period of a few hours or less. Any unevap- orated material can be recovered or will

biodegrade.

RE-USE RECYCLING AND BENEFICIAL

The best recycling technology for Actrel cleaners is filtration and distillation. One of the advantages of these products is the low olefin content and narrow dis- tillation range which allows for high recovery during distillation. Depending on economics, either off-site or on-site distillation may be preferred.

Although recycling is encouraged, in some cases, disposal may be required. When required, fuel blending and sub- stitution for valuable resources, such as coal and natural gas, are the preferred disposal options.

LOW TOXICITY AND SKIN IRRITATION All Actrel cleaners have a very low degree of acute, oral and inhalation toxicity. None of the recommended grades requires labeling or classification under OSHA's Hazard Communication

1 1 1 -TCA Actrel Cleaners Actrel cleaners are notable by their rela-

(OEL) ranging as high as 300 ppm. The OEL is the airborne concentration to which nearly all workers may be repeatedly exposed without adverse affect.

Another parameter used to measure the degree of airborne hazard of a sub- stance is the Inhalation Hazard Index (IHI) which is the ratio of the vapor pressure of a substance to its OEL. Thus, the higher the IHI, the greater the degree of risk. As seen on the chart, the IHI of Actrel cleaning agents is much lower than that of CFC-113 or 1 1 1 -TCA.

There are a variety of ways to use Actrel cleaners in a cleaning process. The diagram outlines some of your options:

EFFECTIVE C L E A N I NG AND DRY1 NG PROCESSES CLEANING STEPS

Actrel cleaners may be used in a variety of liquid-phase cleaning operations including:

- Immersion, assisted if necessary by ultrasonics, immersion spray (spraying below the liquid level in a bath), or parts agitationhotation.

- Flushing

- Low pressure spraying (hosing), as long as the cleaner is applied as a continuous liquid stream (not a fine, atomized or shower-type spray).

- Wiping

High pressure spraying, or other processes that form mists containing fine droplets should be avoided, unless performed in an inert environment, or in equipment protected from ignition sources. This is because ignition of these mists can occur at temperatures signif- icantly below the bulk flash point.

Multiple cleaning stages can be utilized to increase the level of cleanliness or extend cleaner life. In all processes, it is important that the equipment is properly designed to minimize risks associated with the combustibility of the products (e.9. meet the appropriate fire and electrical codes) and to reduce emissions.

Cleaners with flash points near 104" F (40" C) should only be used in unheated equipment near ambient temperatures. Higher flash point cleaners can also be used in ambient temperature processes, or if necessary, temperatures can be elevated to boost cleaning performance. For systems with good control (inde- pendent temperature sensors, cutouts, etc.) Exxon Chemical and the most recent standards of the National Fire Protection Association (NFPA 30, 1990, and NFPA 34,1989) recommend a minimum safety margin of 30" F (17" C) between the cleaner flash point and the cleaning temperature. This will ensure that the vapor concentration in the cleaning stages cannot exceed 25% of the lower explosive limit. However, there are OSHA standards based on earlier versions of NFPA, which recommend a higher margin of safety. You may want to contact OSHA for an interpretation.

DRYING STEPS Depending upon the properties of the particular Actrel cleaner, drying may be accomplished in a variety of ways:

- Ambient temperature drying with either static or forced-air. This is normally used for fluids with flash points near 104" F (40" C).

- Heated forced-air drying if the tem- perature IS at least 30" F (1 5" C) below the flash point of the cleaner. Drying temperatures higher than this limit can be used if sufficient volumes of air are supplied to keep the vapor concentration well below the lower explosion limit of the product. The hydrocarbon concentration should be monitored with detectors. If inert gases, such as N2 or C02, are used, higher temperatures may again be used.

- Vacuum drying. Drying time can be reduced 2 to 5-fold below that ob- tained at atmospheric pressure. Safety-Kleen Equipment Systems has constructed the 4-stage machine shown. It incor-

porates ultrasonics, immersion spray, parts rotation, heated dtying, and the various desian criteria specified in the €PA Control Technique Guide. - Ambient temperature rinsing with a

faster evaporating cleaner to remove slower evaporating materials, and allow drying with ambient temperature forced-air.

- Static "drying" for temporary thin film corrosion protection. This is most effective with high flash point products. Degrees of temporary corrosion protection vary greatly, and must be determined for specific metallurgies, storage environments and part con- figurations.

In addition, drying times may be sub- stantially shortened by film reduction techniques such as parts rotation, centrifugation, air knife (if utilized with a booth or hood to contain and coalesce mists), squeegee or wiping.

OPERATING EQUIPMENT, NEW AND OLD There are a number of cleaning equip- ment manufacturers who have developed cleaning machines for Actrel cleaners.

It is also possible to retrofit or modify existing degreasing equipment that previously used halogenated solvents to safely handle Actrel cleaners. The procedure first requires examination by qualified personnel in such areas as process design, operating procedures, electrical compliance, and materials compatibility. Following this, investment may be needed in such areas as elec- trical equipment upgrades, new level controllers, high temperature shut-offs, new seals and gaskets, etc.

VOC Regulations

The release of volatile organic compounds into the atmosphere is being more tightly regulated to reduce air pollution in industrial areas. The prime regulatory initiatives are the federal 1990 Clean Air Act Amendments (CAAA), together with an array of state and local regulations. This document summarizes the regulatory status and emissions control technologies as they relate to Actrel cleaners.

Overview of State and Federal Regulations

State and local regulations At present, approximately 38 states have some form of VOC control legislation, either state wide or on a county or local basis (see map). For metal cleaning, these regulations are usually quite similar as they are based on Control Technique Guides developed by the Environmental Protection Agency (EPA). These guides specify certain cleaning equipment design and operating parameters, depending on the chemical composition and volatility of the cleaning agent.

The EPA is in the process of developing an updated draft rule for solvent metal cleaning. The intent is to develop a model that can be adopted uniformly by the states.

Federal 1990 Clean Air Act Amendments Additionally, the 1990 CAAA require the states to develop adequate emissions regulations for about 1 00 classified ozone non-attainment areas (see chart A). Facilities emitting more than the specified limit of VOC and NOx will be required to implement controls. The limits are dependent on the area classification.

Regulatory Status of Actrel Cleaners

Photochemically non-reactive Because Actrel cleaners have low levels of aromatics, olefins and branched ketones, they are defined as photochemically non-reactive by California South Coast Air Quality District Rule 102 (old rule 66). This definition is incorporated in most state regulations for VOC control.

Comparison of ActreP Cleaning Systems to Aqueous Cleaning

Aqueous cleaners are mixtures mostly involving water, builders (silicates, phosphates, borates), chelating agents, surfactants (detergent wetting agents) and corrosion inhibitors. The most common aqueous cleaners are alkaline cleaners. Semi-aqueous or emulsion cleaners are not included in this comparison.

Actrel cleaners are a mixture of aliphatic hydrocarbons or oxygenated hydrocarbons, such as linear paraffins, branched paraffins or cycloparaffins.
