摘要
酒精(乙醇)提纯工艺属于间歇反应,目的是将纯度为95℅～98℅的酒精经过三重蒸馏生成达99.99℅以上纯度。本系统中将提纯过程分为进料﹑精馏和出料三个阶段。利用OMREN PLC对三个阶段进行控制以达到提纯的目的。
Purification process of alcohol is an intermission reaction, the purpose is to make alcohol of between ninety-five and ninety-eight percent consistency become over ninety nine point ninety nine percent alcohol via a triple distillation.The system is divided into three phases：the entering phase, the rectifying phase and the exit alcohol phase. The system can control three phases to purify alcohol by using OMREN PLC.
