| 摘 要： | 某厂1999年底建成的年产万吨氯乙酸生产装置采用了自动控制系统。本文在对该自动控制系统进行全面分析之后，针对其结晶釜温度控制方案提出了具体的改进措施,即将原系统使用的预热水罐更换为体积大小合理的预热水槽，并按过程控制原理对预热水槽施加 一定的控制方案，以降低结晶釜夹套的进水预热过程和釜内温度控制过程的耦合度，提高氯乙酸结晶工序的控制性能。

| Abstract: | An automatic control system was adopted in a factory for producing MAC (10 000 ton a year),which was constructed at the end of the year 1999.This article prompts a concrete improvement in the temperature control scheme of the crystallization utensil.In this article,a proper preheating tank is proposed to be used in the procedure of MCA's crystallization. And if a certain control method is exert on it,the coupling degree between the process of the preheating water for the crystallization pot and the process of the control of the crystallization temperature can be reduced,so the control function of the crystallization procedure will be improved. |
