COMPOSITION FOR DESTRUCTION OF WATER-OIL EMULSIONS AND PURIFICATION OF WASTE WATERS CAPABLE OF INHIBITING HYDROGEN SULFIDE AND CARBON DIOXIDE CORROSION AND ASPHALTENE-TAR-PARAFFIN DEPOSITS Russian patent published in 2000 - IPC

Abstract RU 2152425 C1

FIELD: crude oil treatment. SUBSTANCE: composition contains 10-80% of glycerol- based ethylene oxide/propylene oxide block copolymer, 5-80% of ethylenediamine- and/or glycerol-based ethylene oxide/propylene oxide block copolymer, and solvent - the balance. In preferable embodiment, composition also contains 2-7% of a nitrogen-containing compound. Crude oil is dehydrated to residual water content 0.14-0.20% when composition is used in quantity 15-25 g per 1 t crude oil and protective effect against corrosion is 88-97% with 25-50 g/t of composition. EFFECT: improved desired characteristics of composition. 2 cl, 4 tbl
