An additive composition for improving the cold flow properties of crude oils or fuel oils such as middle distillate fuel oils comprises an addition product or condensate cold flow improver additive in combination with a demulsifier.
The invention also relates to compositions containing polyorganosiloxane demulsifier and the water and oil phases of an emulsion.
The invention also relates to compositions containing the above-described demulsifier and the water and oil phases of an emulsion.
Oil is then separated from the mixture of oil, water, demulsifier, and brine solution.
The fuel additive compositions of the invention include a dispersant; a demulsifier; a metal deactivator; and an antioxidant.
The vacuum distillation is carried out in the presence of, for example, a silicone defoaming agent (61) or a silicone defoaming component.
The emulsion-breaking additive can be native to the process stream.
The invention further comprises a continuous or batchwise process for breaking an oil/water emulsion by adding emulsion breakers, wherein the required amount of emulsion breakers is determined by said process and is added to the emulsion.
This invention relates to compositions comprising a volatile hydrochlorofluorocarbon such as 1,1-dichloro-1-fluoroethane and deemulsifier.
The sizing compositions may further include polymeric additives, aqueous alkali, a pigment and a defoamer.
The first preset condition is preferably that the turbidity value increases with further addition of the organic emulsion breaker.
Optionally, a de-emulsifier is added to at least one of the contacting and separating steps.
Engine oil is mixed in this analysis container, with a reagent including alcohol and a de-emulsifying agent.
The rinse aids are prepared by combining the high cloud point copolymer with an effective defoamer and a water miscible diluent.
The destabilization or breaking is instigated by the addition of an emulsion breaker or heat to the emulsion in sufficient quantity to provide the desired break time.
The present invention includes the use of anhydride compositions, including alkyl and aryl anhydrides, for use as a denmlsifϊer in resolving emulsions of water and oil.
The volume of the defoamer (5) is in the range of 2.0 x 10-3 - 0.2 mg per 1 mL of blood collected into the blood collecting container (1).
The crude oil/water phase stream is contacted with a dosage of an emulsion breaker in an applied electric field.
Treatment gas can be introduced at nozzles (40) and other treatment material e.g. defoaming agent can be introduced at axially spaced nozzles (43).
In the present invention, the oil in water emulsion is treated with an emulsion breaker or destabilizer so that the emulsion is destabilized or broken after application to the surface to be treated.
