Based on the characteristics of electric dehydration of crude oil, a control system on PLC is designed.

从原油电脱水系统的特点出发，设计基于可编程序控制器的电脱水控制系统。

In the later period of oilfield development, high water cut in produced fluid and unstable produced fluid volume may cause big and frequent disturbance in the electric dehydration system of crude oil.

油田开采后期，采出液中含水率很高且采出液量极不稳定，这就导致原油电脱水系统频繁受到大的干扰。

The results of dehydration and desalting of crude oil were compared between with ultrasound combined with electrical desalting and with electrical desalting only.

实验比较了超声波电脱盐联合作用和单一电脱盐作用的脱盐脱水效果。
