萃取精馏系统控制研究

Study on the Extractive Distillation System Controlling

萃取精馏系统是精馏过程中常用的三种形式之一。完成此过程一般需要三个或者三个以上的精馏塔完成,且系统中流股耦合严重,故系统控制一直是国内研究的热点。文章就萃取精馏系统控制方面的研究进展做了概述。

Extractive distillation system is one of the three common forms of distillation system.To complete this process,three or more typically distillation tower should be used,and the streams of the system coupled seriously.Then,the system controlling has been a hot spot in research.In the paper,research of extractive distillation system controlling is brought out.
