  • Preparation of improved stable crude oil transport emulsions
    Patent number: 4978365
    Abstract: A process for the production of an oil-in-water emulsion for pipeline transmission. The process comprises producing a hydrocarbon crude, and mixing the produced hydrocarbon crude with an emulsifying composition(s) which contains water and is capable of assisting the formation of an oil-in-water emulsion when the temperature of the mixture of produced hydrocarbon crude and emulsifying composition(s) is from about 100.degree. F. to about 200.degree. F. The amount of the emulsifying composition(s) that is mixed with the produced hydrocarbon crude is sufficient to form an oil-in-water emulsion having water content of from about 15 percent to about 60 percent by weight water and a viscosity sufficiently low for pipeline transmission. The process additionally comprises shearing and mixing the mixture of produced hydrocarbon crude and emulsifying composition(s) when the mixture is at a temperature of from about 100.degree. F. to about 200.degree. F. to form an oil-in-water emulsion.
    Type: Grant
    Filed: October 27, 1987
    Date of Patent: December 18, 1990
