改进三相分离工艺实现脱水脱盐一次达标

Improve 3-phase Separator Technology to Realize Desalinization-Dewater Qualified Once

在“四合一”基础上进行结构改造的三相分离器，用于油田生产，可大大简化工艺流程。并配合优选的破乳剂，使原油脱盐脱水可以在较低温度下运行。脱水后原油含水小于0．3％，含盐小于140mg／L。

3-phase separator, on the basis of ' 4 in one' and structure-improved,can be used in oilfield production,simplifies process flow greatly and combining with optimizing demulsifying agents makes crude desalinization-dewater can be done under lower temperature. The water cut of dewatered crude less than 0. 3 % and salts cut less than 140 mg/L.
