| titleOfInvention | method of solving an emulsion of water and crude oil |
| abstract | demulsifying composition and method of using it. the present invention relates to a microemulsion-based demulsifying composition and a method of demulsifying an emulsion comprising hydrocarbon and water. the demulsifying composition includes (i) an oil-like phase comprising at least one non-ionic surfactant, having a hydrophilic-lipophilic (hlb) balance of less than about 9; (ii) a coupling agent capable of stabilizing the demulsifying composition; (iii) at least one dispersible or water-soluble non-ionic surfactant that is different from at least one non-ionic surfactant in the oil-like phase; (iv) at least one additional surfactant selected from anionic, cationic, amphoteric and combinations thereof; (v) at least one nonionic demulsifier; and (vi) water. |
