DEHYDRATING AND DESALTING COMPOSITIONS OF CRUDE OILS, USING TRIBLOCK COPOLYMERS ALPHA,OMEGA-BIFUNCTIONALIZED WITH AMINES.

摘要

Compositions consisting of block copolymers [alpha],[omega]-di-aryl or alkyl sulfonates of poly(ethylene oxide)w-poly(propylene oxide)-poly(ethylene oxide)w of bis-ammonium and block copolymers [alpha],[omega]-di-amine of poly(ethylene oxide)w-poly(propylene oxide)-poly(ethylene oxide)w, are provided that are effective in the dewatering and desalting crude oils whose specific gravities are within the range of 14 to 20 DEG API.
