DEHYDRATING AND DESALTING COMPOSITIONS OF CRUDE OILS, USING TRIBLOCK COPOLYMERS ALPHA,OMEGA-BIFUNCTIONALIZED WITH AMINES |
| 摘要 |
Compositions 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, are provided that are effective in the dewatering and desalting crude oils whose specific gravities are within the range of 14 to 20° API. A method of dewatering and desalting heavy crude oil adds a mixture of the copolymer bifunctionalized with an aliphatic or aromatic secondary amine and a copolymer bifunctionalized with an aliphatic or aromatic tertiary amine. |
