乙烯精馏塔稳定化控制策略

A Stability Control Strategy for Ethylene Rectifying Tower

本文以高压法双塔乙烯精馏塔流程为例，分析了该工艺过程的操作要素及静态前馈-反馈控制模型的建立方法，并探讨了该工艺过程的稳定化控制策略。

Taking the process flow of double - tower type ethelene rectifying towr as example,this paper analyzes its operatios and the construchng method of static feedforward-feedback control medel; and at last discusses its stability control straegies.
