新技术在常减压装置中的应用——Agar电脱盐界位控制系统

Application of New Technology in Crude Distillation Unit——Agar Desalter Interface Control System

电脱盐罐内油水界位的控制,对电脱盐罐的平稳运行具有重要的意义。简要介绍了Agar电脱盐罐界位控制系统结构及原理,同目前使用控制系统做了对比。结果表明,在电脱盐罐上采用Agar界位控制系统,可以优化液位控制,减少原油带水及排水含油的发生,降低污水处理的难度,有利于节能减排。

The controlling interface between oil and water in the desalter has great meaning for stable operation.In this paper,structure and principle of Agar desalter interface control system were introduced and compared with traditional control system.The results show that the application of Agar system can optimize the interface control and reduce water content in the desalted oil or oil content in the effluent,which is beneficial to energy saving and emission reduction.
