METHOD OF PREPARING DEMULSIFIER FOR DESTROYING WATER-OIL EMULSIONS Russian patent published in 2000 - IPC

Abstract RU 2152422 C1

FIELD: crude oil treatment. SUBSTANCE: demulsifier is prepared by interaction of with oxyethylated fat acid-based amine followed by addition of phosphorus-containing compound. Molar ratio of (ethylene oxide+propylene oxide)/amine/phosphorus-containing compound is 1:(0.1-0.5):(0.1-3). In a preferred embodiment of invention, to interaction product is added solvent. EFFECT: increased efficiency in destruction of oil emulsions and achieved protective effect against corrosion of equipment and asphalt-paraffin tar deposits. 2 cl, 5 tbl, 38 ex
