Demulsifier
Demulsifier is a formulated product and this formula depend upon the Properties of crude oil e.g. such as: paraffin, asphalt, API, emulsion, Salt, water contain, gases contain
A demulsifier is recommended to break oil field oil/water emulsions and aid in solids removal from liquids providing a high quality produced crude and clean effluent water. These emulsion breakers w
ork by attacking the droplet interface causing the droplets to disperse or gather into larger droplets. This action causes a density change making it easier for separation to occur. Factors that influence the type of demulsifier selected include the type of emulsion, either oil-in-water or water-in-oil, and the API gravity of the crude. Evaluation of the rate of water drop, sharpness of oil/water interface, and cleanliness of the water are included in analyzing for the proper demulsifier. In oil production systems, water is often present in the reservoir and is co-produced with the oil. Due to the presence of emulsifying agents, such as:
• Naturally occurring surfactants in the oil / water
• Silts, fine solids, drilling mud, and clays
• Shearing effects resulting from turbulent flow and pumps, these fluids combine to form an emulsion
• Water and steam floods. Water clarifiers or reverse demulsifiers are also available for aid in removing oil and solids from oil field and industrial waters. The need for chemical demulsifiers is seen in almost every industry segment; anywhere oil and water are used. Major users of demulsifiers include the following industries: steel, aluminum, chemical processing, petroleum refining, fuel washing prior to gas turbines, slop and tramp oil treatment, and in the processing of crude oil in the oil field, both to treat synthetic mud’s and to treat the produced hydrocarbons. The type of demulsifier selected depends on whether the emulsion is water-continuous or hydrocarbon-continuous. And whether the solids or other impurities are desired in the water layer or are to be incorporated in the oil layer. RIMPRO produces a wide range of demulsifiers, which are used to “break” emulsions (that is, separate the two phases – oil and water). Our demulsifiers are available as medium concentration of surfactant for oil-in-water emulsions (water soluble) or hydrocarbon-soluble liquids for water-in-oil emulsions.(oil soluble)
OIL SOLUBLE DEMULSIFIER
RIMPRO OILSOLUBLE DEMULSIFIER SERIES is a totally organic liquid formulation of surfactants and dispersants in a water and soluble in toluene, Xylene, Aromatic solvent, crude oil for the demulsification of water in oil and oil in water, capable of performance at room temperature, but with improved speed and percentage of oil removed when applied at temperatures near 60 deg. RIMPRO demulsifier destabilizes the oil-water interface that surrounds each water particle in the emulsion, replaces the emulsifier molecules (if any), and allows the water to coalesce. RIMPRO demulsifier is a completely combustible, non-abrasive; non-ash-forming treatment, which will improve the quality of the fuel it, is added to
CHARACTERISTICS:
Physical appearance Homogenous Liquid
Density 0.9 +- 1.0
Solubility: Toluene, xylene, crude oil, aromatic solvent
PH range 6.5 to 8.0
Soluble in water Dispersion & Insoluble
ADVANTAGES:
• does not stay with the water phase, therefore does not contribute to water pollution
• Stays with the fuel and actually improves burning characteristics of the fuel
• uses lower dosages than most competing products
DOSAGE: Because of the diverse nature of oil and waste amenable to treatment with RIMPRO demulsifier, specific recommendations have to be made on a case-by-case basis. The dosage of RIMPRO demulsifier prescribed to break a particular emulsion varies from as little as 1 gallon per 20,000 gallons (50 ppm) of oil to as much as 1 gallon per 10,000 gallons (100 ppm) of oil. A few clients have even found that 20 ppm was more effective than the higher dosages, so we suggest adding the lower levels to your laboratory bench tests to verify the correct dosage for the specific application. Finding the most cost-effective dosage, as well as determining the best conditions of temperature, slow mixing, settling time, etc., is best done in the laboratory, using a sample of the actual oil or waste and a sample of RIMPRO demulsifier
APPLICATION: Once you have determined the correct dose of RIMPRO demulsifier, fill the tank with the waste-oil-water solution and inject the correct dose of RIMPRO demulsifier directly from the drum. Mix thoroughly, with the assistance of a pump, for two to five hours. Mixing time varies depending on the size of the tank and the speed of the motor. Allow the fuel to settle and check for water separation. Depending on the configuration of the tank, either remove the water by means of a drain in the bottom or suck the clean oil off from the top of the tank. WATER SOLUBLE DEMULSIFIER

A few clients have even found that 20 ppm was
more effective than the higher dosages, so we suggest adding the lower levels to your laboratory bench tests to verify the correct dosage for the specific application. Finding the most cost-effective dosage, as well as determining the best conditions of temperature, slow mixing, settling time, etc., is best done in the laboratory, using a sample of the actual oil or waste and a sample of RIMPRO demulsifier
Disadvantages of Oil soluble Demulsifier
Present of aromatic solvent and then other solvent properties is toxic and/or inflammable/combustible
Special safety procedure for handling of material
Cost wise higher then water-soluble
Flash point is a problem of oil soluble demulsifier, if the flash point is less then 50 the product is store in special air environment conditioning otherwise explosion or to crake the drum or /and when open the drum high gases of solvent are evaporate
Salt are not easily dilute or removed in oil soluble they required extra does of demulsifier
Asphalt and paraffin are soluble with crude and effected for final product because some of the solvent are soluble in asphalt and paraffin wax

Corrosion in the Oilfield
The production of gas and oil is often accompanied by water, either from the formation, from condensation, or from water injected as lift assist. Acid gases, such as hydrogen sulfide (H2S) and carbon dioxide (CO2) are often present in produced fluids, and oxygen is sometimes a contaminant in the water used for injection. These acid gases increase the corrosively of the waters to steel, and can significantly impact the safe operating life of production tubular and equipment, production vessels, and transportation systems. The presence or absence of multiple phases (gas, water, and oil or condensate) in the same system can complicate the problem of controlling corrosion. The flow regime or pattern of fluids in a tubing string, vessel, or pipeline can have a significant impact on corrosivity. If a well or pipeline experiences "slug" or intermittent flow, highly corrosive conditions may exist in the area of the pipe in slug flow. Pipelines can experience top-of-line corrosion when conditions promote the rapid condensation of water in a cooler section of the line, causing a film of water to form at the top of the line. This water at the top of the pipe becomes saturated with acid gases and corrodes the pipe. A further complication is a change in conditions, such as flow rate, temperature, and pressure over the life of a well, production or processing system, or pipeline, which can result in changing corrosivity or even a change in the potential corrosion mechanisms. The control of corrosion in the oilfield can be a complex problem, requiring detailed analysis and a thorough understanding of the range of conditions expected during the life of the system prior to the development of a corrosion management plan. RIMPRO CORROSION INHIBITOR product line consists of a number of corrosion inhibitor formulations - some have been developed to address specific corrosion problems and others have been formulated to have wide applicability. RIMPRO inhibitor products are proven performers with a solid history of "raising the bar" in providing cost-effective corrosion protection in all oilfield operations. Applications include controlling corrosion in all types of oilfield operations, including oil and gas production, processing, and transportation systems. Formulating an effective corrosion inhibitor is a complex task. Laboratory and field-testing are often required for development of a corrosion inhibitor. The first step in formulating a corrosion inhibitor is determining the inhibitor’s intended application in the oilfield production system.

Applications RIM 105 inhibitor is effective at relatively low concentrations in all water base muds. It has proven to be particularly useful in reducing oxygen corrosion in aerated muds, low solids, no dispersed, polymer muds, and potassium muds. The product should be evenly dispersed throughout the circulating mud system and can be added either through the chemical barrel or directly to the mud pits wherever good agitation occurs. The recommended initial treatment of RIM 105 inhibitor is 2 to 4 gal/100 bbl (0.5 to 1.0 L/m3) depending on anticipated conditions, other chemicals used in the system, and the corrosive environment, te*, salinity, pH, temperature, oxygen content and acid gases. If the corrosion rate is unacceptably high, the concentration should be increased to at least 7 gal/100 bbl (1.7 L/m3). For aerated systems, an initial treatment of 12 gal/100 bbl (2.9 L/m3) is recommended. The corrosion rates should be monitored at all times with corrosion coupons and treatments should be adjusted according to their analysis. A good corrosion control program includes a thorough makeup water analysis, chemical treatments for corrosive contaminants and an adequate bacterial control for systems that contain biodegradable additives.
