电石法氯乙烯精馏低塔尾气的利用

摘要

以40万t／a电石法聚氯乙烯装置为例，对氯乙烯精馏低塔尾气回收进行了详细的计算，表明以变压吸附的方法综合回收精馏尾气可获得显著的经济效益。%The recycling of tail gas from low boiling tower for vinyl chloride rectification for 400 kt/a plant of calcium carbide-process PVC is calculated in detail. It is shown that the recycling of these tail gas by adopting pressure swing adsorption method can obtain great economic benefits.
