氯乙烯精馏工序的技术改造

Technical improvement of vinyl chloride distillation process

对氯乙烯精馏装置进行技术改造,采用垂直筛板塔替代泡罩塔作为高沸塔,提高了精馏装置处理能力,降低了二氯乙烷含量,提高了氯乙烯单体的质量。

Vinyl chloride distillation high boiling tower instead of bubble cap was improved, and the quality of vinyl content device was improved. Vertical sieve plate column was used as column. Then the treatment capacity of the distillation device chloride monomer was improved with reduced dichloroethane
