甲醇精馏塔自动控制方案的探讨

An Automatic Control Method of the Methanol Distilling Tower

在精细化工生产中 ,甲醇回收过程是常见的操作过程 ,采用的关键设备为甲醇精馏塔 ,为保证馏出物甲醇的纯度 ,采用自动控制系统

In the produce of the refining chemistry,the recycle of methanol is a common process in which the critical equipment -the distilling tower has much difference with the large facilities.This article makes static and dynamic analysis of the tower and from the point of view of object stir.variation and the control law.It discusses the automatic control system which aims to guarantee the purity of recycle methanol and decrease wasted energy.Compared with the manual control process,the automatic one can stop the stir quicker andguarantee the quality of the product.
