河南油田炼油厂50万吨/a常减压装置于1992年建成，电脱业采用国产的交流电脱业设备．随着原油日益变重和含水量的不断增加，生产中脱业装工变压器跳闸频繁，影响装里的平稳操作，且脱业效呆逐渐变差，为此，1996年对炼油厂原电脱盐装置进行了交直流电脱盐技术改造．两年多的生产运行表明，脱盐脱水效果有了明显改善，达到了中石化要求的脱后食盐小于3mg／L、合水小于0．1％和污水含油不大于200mg／L标准，同时耗电量下降81％左右，不但解决了生产中存在的问题，而且创造了显著的经济效益和社会效益。
Henan Oilfield refinery 500,000 tons / a atmospheric vacuum unit was completed in 1992, the electricity off the use of domestic AC power off equipment. With the increasing weight of crude oil and increasing water content, tripping of production transformers frequently occurs during tripping, affecting the smooth operation of the installation and the gradual deterioration of deactivation efficiency. Therefore, in 1996, Equipment for the AC and DC desalination technology transformation. More than two years of production and operation showed that the desalination and dehydration effect has been significantly improved to meet the requirements of Sinopec off the salt is less than 3mg / L, combined water less than 0.1% and sewage oil not more than 200mg / L standard, while the power consumption Down about 81%, not only solved the problems in production, but also created significant economic and social benefits.
