双塔处理吸收废氯气的探讨

Discussion on absorbing waste chlorine gas by two columns

提出烧碱生产中采用双塔分别吸收废氯气工艺,代替事故塔、尾气吸收塔、次氯酸钠生产装置吸收废氯气,具有自动化程度高、可连续运行的优势。

A two-column treatment process for absorbing waste chlorine gas is put forward to replace the original process which is composed of an accident column, a tail gas absorption column and produc- tion device of sodium hypochlorite. The new process has the advantages of high automatic level and con- tinuous running.
