DEEMULSIFIER FOR DESTRUCTION OF AQUEOUS PETROLEUM EMULSIONS Russian patent published in 1999 - IPC

Abstract RU 2141502 C1

FIELD: processing of petroleum. SUBSTANCE: in order to destruct aqueous petroleum emulsions, deemulsifier comprises, wt %: ethylene-propylene oxide glycerol based block copolymer having links of ethylene oxide of 1-40 and propylene oxide of 60-99 and molecular weight of 3000-6000 conventional units, 20-90, and the solvent balance. Deemulsifier has higher efficiency when treating highly flooded petroleum emulsions containing asphaltenes resins and paraffins. Deemulsifier is used to facilitate sewage purification. EFFECT: improved properties of the deemulsifier. 15 ex, 1 tbl
