淡盐水脱氯工艺技术应用研究

Research on application of dechlorination process by depleted brine

从离子膜烧碱生产过程中淡盐水产生游离氯的根源入手,分析研究了淡盐水脱氯的基本原理和方法,并对各种脱氯方法进行了比较,确定了操作关键点和易出现的问题及处理措施。

The theory and method of dechlorination of depleted brine were analyzed from the reason of production of free chlorine, which is in production process of caustic soda by ionic membrane method. After the comparison of several methods of dechlorination, it decided that key operation point, existing problem and treatment.
