Abstract RU 2213123 C1

FIELD: crude oil treatment. SUBSTANCE: composition contains, wt %: glycerol-based ethylene oxide/propylene oxide block copolymer, 17-19; ethylenediamine-based ethylene oxide/propylene oxide block copolymer, 33-37; demulsifier (additionally), 5-6; methanol, 30-35; and water, the balance. Demulsifier is composed of, wt %: dimethyl phosphite 0.35-0.5, amine or triethanolamine 0.35-0.5, alkylphenol 14.0-19.0, "Fosfenoks N-6" 9.0-25.0, "Diproksamin-157" or "Diproksamin-157-65M" 15-30, and solvent - the balance. EFFECT: enhanced efficiency of composition in case of high-viscosity crude oils. 3 tbl, 7 ex
