偏氟乙烯制备中副产氯化氢的干法分离可行性研究

Study on the Feasibility of Dry Separation By-product Hydrogen Chloride from 1,1-Difluoroethylene

国内的偏氟乙烯生产装置一直采用传统湿法分离副产氯化氢。通过相应的模拟计算,探讨干法分离氯化氢的可行性,从而达到基本杜绝副产盐酸的产生,大大降低偏氟乙烯生产的废液量,减轻环保负担。

The domestic manufacturing devices of 1,1- difluoroethylene have been using traditional wet route to separate hydrogen chloride. In this article,through the corresponding simulation calculation,to study the feasibility of dry separation of hydrogen chloride. So as to eliminate the by- product hydrochloric acid,and greatly reduces the amount of liquid waste,reducing the environmental burden.
