提高氯气干燥效果的措施

Measures on improving the effects of chlorine gas drying

阐述了在隔膜法烧碱生产过程中,因氯气含水多、干燥塔板积液和塔板上无泡沫层等造成氯气干燥效果不好导致酸流量调节困难,并影响设备使用寿命的问题。提出了具体有效的整改措施。

In diaphragm caustic soda production, because water content being too much or liquid build-up on drying column tray or with no foam layer on column tray, the chlorine gas drying effect was bad. And it was difficult to adjust acid flow. Moreover, the service-life of units was shortened. Some concrete and effective measures for rectifying above status was put forward.
