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