聚氯乙烯生产中副产废酸的平衡设计及其节能减排效果

The design for the balance of waste acid by-product in the production of PVC and its energy-saving and emission-reducing effects

介绍了PVC生产中副产废酸的深解吸工艺,该工艺达到了废酸零排放、零销售及循环利用的目的。按新疆天业集团天辰化工公司40万t/a PVC计,每年回收废酸可产生经济效益2 680万元。

The deep stripping process of waste acid adopted in the production of PVC was introduced. The process could achieve the aims of zero discharging, zero selling and reutilization of waste acid. Based on the production of 400 kt/a PVC in Tianchen Chemical Co. of Xinjiang Tianye Group,26.80 million RMB ￥ benefits could be achieved from the recovery of waste acid per year.
