氯乙烯精馏尾气变压吸附装置及氢气提纯回用装置技术改造

Technical improvements on VCM distillation tail gas pressure swing adsorption device and on hydrogen purification and reuse device

介绍了电石法PVC生产过程中氯乙烯精馏尾气变压吸附装置以及氢气回用装置的技术改造。改造后,精馏尾气实现了达标排放,氢气可以稳定地回收使用。

The technical transformations on pressure swing adsorption device for VCM rectification tail gas and on hydrogen recovery device in calcium carbide method PVC production were introduced. After transformation, the emission of rectification tail gas met the discharge standard and the hydrogen was stably recycled.
