呼和浩特石化公司现有的原油电脱盐装置不仅破乳剂消耗量大,而且脱盐效果也并不是很理想。本次停工检修使用了超声波-电脱盐组合工艺,具有无污染、能耗低、投资少、效果好等技术优点,对原油性质变化也具有更强的适应能力。其技术在DCS上的实现有一定的难度,灵活运用DCS现有的模板,完全达到工艺使用要求。
The existing crude oil desalination equipment of Hohhot Petrochemical Company not only consumes large amount of demulsifier, but also desalination effect is not very satisfactory. The suspension of the use of ultrasonic repair - electric desalination combination of technology, with pollution-free, low energy consumption, low investment, good effect and other technical advantages, the nature of the changes in crude oil also has a stronger ability to adapt. The realization of its technology in DCS has a certain degree of difficulty, flexible use of existing templates in DCS, fully meet the process requirements.
