摘要
阐述了氯乙烯合成工艺混合气中游离氯含量超标现象的危害,介绍了陕西金泰氯碱化工有限公司混合气中游离氯含量超标报警技术,该技术采用DCS同时检测混合器出口温度及一级冷凝器出口温度的上升速率,可实现混合气中游离氯含量超标检测并报警。
The damage caused by the free chlorine content exceeding limit in process mixed gas for the synthesis of vinyl chloride was claborated. The alarm technology for the free chlorine content of mixed gas exceeding limit adopted by Shaanxi Jintai Chlor-Alkali Chemical Co. ,Ltd. was introduced. This technology could inspect the rising ratc of mixer outlet temperature and the first condenser outlet temperature at the same time,which could realize the determination and alarm for the free chlorine content of mixed gas beyond limit.
