摘　　要：为了解决粗氯乙烯单体水含量过高对精馏系统和聚合系统产生的不利影响,对氯乙烯精馏系统水分离器放水过程进行改造,由人工操作改造为DCS自动控制,提高了精馏系统运行的稳定性和氯乙烯单体产品的质量。In order to address the adverse effects of high water content in the crude vinyl chloride monomer on the distillation system and polymerization system,the water discharge process of the water separator for vinyl chloride distillation system was transformed from manual operation to DCS automatic control,which improved the operational stability of the distillation system and the product quality of vinyl chloride monomer.
