Abstract

Abstract: Crystal packed-bed crystallizer is designed and used to separate and purify para-dichlorobenzene from a mixture of para- and ortho- dichlorobenzene. The effect of operation parameters such as the height of crystal packed-bed, reflux ratio, feed concentration and agitation rate on the separation performance of the crystallizer are investigated, and the operation process of crystallization is analyzed.

摘要： 用设计的晶体填充床结晶器,从对二氯苯、邻二氯苯的混合物系中分离提纯对二氯苯,考察了晶体床层高度、回流比、进料浓度、搅拌转速等操作因素对结晶器分离性能的影响,并分析了结晶器的操作过程.
