聚氯乙烯生产过程中聚氯乙烯粉末回收探讨

Introduction to the recovery of PVC powders from PVC production

介绍了聚氯乙烯生产过程中离心母液水及干燥外排尾气中聚氯乙烯粉末的回收情况。以30万t/a聚氯乙烯装置为例,回收离心母液水中的聚氯乙烯粉末约352.8 t/a,回收干燥后外排尾气中的聚氯乙烯粉末约131.2 t/a。

Thc recovery situation of PVC powders from the centrifugal mother liquid and the outward-dischargcd dry tail gas was introduccd. Taking 300 kt/a PVC plant as example, ncarly 352.8 and 131.2 tons of PVC powders could be recovered pcr year from the centrifugal mother liquid and thc outward-dischargcd dry tail gas, resp.
