The present invention is related to formulations consisting of block copolymers α,ω-di-aryl or alkyl sulfonates of poly(ethylene oxide)w-poly(propylene oxide)-poly(ethylene oxide)w of bis-ammonium and block copolymers α,ω-di-amine of poly(ethylene oxide)w-poly(propylene oxide)-poly(ethylene oxide)w, that are effective in the dewatering and desalting crude whose specific gravities are within the range of 14 to 23°API.
本发明涉及由聚(环氧乙烷)w-聚(环氧丙烷)-聚(环氧乙烷)w 的双铵嵌段共聚物α,ω-二芳基或烷基磺酸盐和聚(环氧乙烷)w-聚(环氧丙烷)-聚(环氧乙烷)w 的嵌段共聚物α,ω-二胺组成的制剂,这些制剂可有效地对比重在 14 至 23°API 范围内的原油进行脱水和脱盐。
