从氯乙烯精馏尾气中回收氢气技术分析

Technical analysis of hydrogen gas recovery from vinyl chloride distillation tail gas

氯乙烯精馏尾气经变压吸附回收氯乙烯、乙炔后,排空的尾气中含有大量氢气。通过变压吸附技术对富氢气体进行回收,使净化后的气体达标排放,降低消耗,减少环境污染。

After the vinyl chloride distillation tail gas was pressure swing adsorbed to recover vinyl chloride and acetylene, the vent gas contained a large amount of hydrogen gas. The hydrogen-rich gas was recovered by pressure swing adsorption technology, and thus the purified gas met discharge standard, material consumption was cut down and environmental pollution was reduced.
