摘　　要：叙述了聚氯乙烯生产中高沸物二氯乙烷的生产现状和发展前景。对二氯乙烷精馏过程进行模拟,采用间歇精馏技术对2 500 t/a高沸物进行回收利用,并进行设备核算和经济效益分析。结果表明:对聚氯乙烯生产中的高沸物进行回收利用具有显著的经济效益和社会效益。The current situation and development prospects of high-boiling dichloroethane formed in PVC production were described. Through simulating the distillation process of dichloroethane,2 500 t / a batch distillation equipment was adopted to recover the high-boiling compounds,and the equipment accounting and economic effects were analyzed. The results showed that the recovering produced remarkable economic effects and social effects.
