氯乙烯尾气排放中存在氢气的浪费和安全隐患问题,通过增加氢回收装置,经运行实践,对提高聚氯乙烯树脂产能和节能减排的环保效果都很明显。 There is a waste of hydrogen gas and potential safety problems in the discharge of vinyl chloride fume. Through the addition of hydrogen recovery unit, the environmental protection effect of increasing the production capacity of PVC resin and saving energy and reducing emissions is obvious.
