Abstract: Rapid dehydration of crude oils containing salt water by addition of minor amounts of polyalkylene polyamines having at least fifty recurring ethylene imine or propylene imine units, the said polyalkylene polyamine being completely alkoxylated at the nitrogen atom with from 10 to 300 moles of ethylene oxide and/or propylene oxide. Using these compounds it is possible to effect dehydration, in an economical manner, of crude oils containing up to relatively large percentages of high molecular weight hydrocarbons.

Abstract translation: 通过加入少量具有至少五十个重复乙烯亚胺或丙烯亚胺单元的聚亚烷基多胺，使含有盐水的原油快速脱水，所述多亚烷基多胺在氮原子下用10-300摩尔环氧乙烷和/ 或环氧丙烷。 使用这些化合物可以以经济的方式实现含有高达相当大百分比的高分子量烃的原油的脱水。
