    摘要: The present invention is directed to a method for producing an emulsified aqueous hydrocarbon solution comprising, providing a liquid hydrocarbon stream at a particular temperature and a separate water stream, mixing the water stream with a surfactant at a predetermined ratio, raising the pressure of the hydrocarbon stream to a pressure greater than the vapor pressure of steam at the temperature, spraying the water into the hydrocarbon stream at a pressure greater than that of the hydrocarbon stream in a pre-mix chamber; and passing the pressurized hydrocarbon-water mixture through a static mixing chamber.

    摘要: Methods for reducing calcium deposition along surfaces in contact with the water phase of a resolved water/oil emulsion are disclosed. High calcium crude oil and the like are contacted with a sequestrant to form a sequestered calcium containing complex that partitions to the water phase in the resolved emulsion. A specifically formulated polymeric deposit control agent is added to the water phase to inhibit calcium deposit formation therein and along surfaces in contact with the water phase.

    摘要: The invention pertains to the use of a class of acetylenic surfactants to resolve or break water and oil emulsions. The surfactants are of particular advantage in resolving crude oil emulsions of the type encountered in desalter and similar apparatus designed to extract brines from the crude as they partition to the aqueous phase in the desalter.
