计算机智能控制系统在精馏装置中的应用

COMPUTER INTELLIGENT CONTROL SYSTEM FOR DISTILLATION PROCESS

介绍了计算机智能控制系统在１氟１，１二氯乙烷（ＨＣＦＣ１４１ｂ）精馏装置上的应用。采用ＧＥＮＥＳＩＳ工控软件，在１台工业控制计算机上实现了ＤＤＣ和ＳＣＡＤＡ功能，并将工艺要求以人工智能的方式综合进ＳＰＣ级，构成计算机智能控制系统。系统投运后，产品纯度从不足９９．９０％提高到９９．９０％以上，产量从２５００ｔ／ａ提高到５０００ｔ／ａ。

The paper presents a new type of computer intelligent control system used in the 1 fluoro 1,1 dichloroethane(HCFC 141b) distillation process. GENESIS for DOS is used to provide DDC and SCADA function to distillation process from only one computer. Using the artificial intelligence method, the experience of process engineers are synthesized into the system's SPC. With the intelligent control,the purity of the product is improved from 99.5% to more than 99.9%, better than that of the product of the Allied Signal Company US.The output of the product is raised from 2500 t/a to 5000t/a.
