COMPOSITION FOR DESTRUCTION OF WATER-OIL EMULSION AND PROTECTION OF OIL-FUEL EQUIPMENT AGAINST ASPHALTENE-TAR-PARAFFIN DEPOSITS Russian patent published in 2000 - IPC

Abstract RU 2152424 C1

FIELD: crude oil treatment. SUBSTANCE: composition contains 20-80% of glycerol-based ethylene oxide/propylene oxide block copolymer with 1- 50 ethylene oxide units and 50-130 propylene oxide units, 2-10% of Dissolvan, and solvent - the balance. Composition ensures sufficiently low content of residual admixtures of water and salts in crude oil and solves problem associated with protection of equipment against deposits of tarry compounds. EFFECT: enhanced desalting and dehydration efficiency and reduced oil pollution of waste water. 2 tbl, 16 ex
