摘　　要：给出氯气处理工艺流程。在氯气处理过程中,干燥是整个处理工艺的关键。造成干燥后氯气的含湿量偏高的原因有工艺设计问题,有设备本身的问题,也有操作上的原因。具体包括:泡罩塔气相温度较高,出泡罩塔气相温度高,出酸浓度过低,塔阻力降过低,塔板倾斜;干燥塔塔板积液,塔板上没有泡沫层。针对各类情况,分析出现这些情况的原因,并给出处理方法。A chlorine gas treatment process is given. In the chlorine treatment process, drying is the key to the whole treatment process. The factors of causing high moisture content of chlorine after drying include process design, equipment itself and operation, such as high gas phase temperature of bubble column, high temperature of bubble column outlet gas, too low acid concentration, too low tower resistance, inclination of tray, liquid accumulation in the dry tower column tray and no foam layer on the tray. In view of various situations, the reasons for these situations are analyzed and the treatment methods are given.
