【摘要】 介绍了当前国内外原油电脱盐的基本概况 ,通过采用低温破乳剂 ,使原油在低温下得到处理净化 ,然后应用新型电脱盐成套设备和高效破乳剂及脱金属剂 ,解决了原油深度脱盐问题。经过对工艺条件进行优化 ,脱盐后盐含量可达到小于 3mg·L-1的水平。更多还原

【Abstract】 Present situation of crude electrodesalting both domestic and abroad was introduced,the crude was purified by adopting low-temperature demulsifire at low-temperature,after the problem of crude oil depth desalting was resolved with applying complete sets of electrodesalting equipment,hight-efficient and demetallization agent.By optimizing the technics situations, when desalting and dewatering, the content of salt in crude oil will reduce to less than 3mg·L -1.更多还原
