氯仿精馏二塔流程探讨

Discussion on the two-column flow path for chloroform distillation

分析由氯仿精馏塔和氯仿蒸出塔组成的氯仿精馏二塔流程中,氯仿蒸出塔的返回量对氯仿精馏塔操作性能、产品收率和蒸汽消耗量的影响。建议将二塔流程改成一塔流程。

The two - column flow path for the distillation of chloroform is composed of a column for chloroform distillation and a column for chloroform recycle. The influences of the volume of return flow from the latter into the former on the operation performance of the former, the yield of product and the consumption of steam are analyzed. The author suggests to replace the two - column flow path by a one - column flow path.
