摘要
Abstract
Extractive distillation could be used for recovery of by-product mixed alcohols from waste water of F-T process.This process contains 7 columns and 5 circles.The reason of the complexity of this process is the formation of azeotropes between water and alcohols except methanol.Zeolite membrane based pervaporation is an advanced separation technology that is not restricted by vapor liquid equilibrium.Therefore,it would be feasible to use zeolite membrane pervaporation to dewater the mixed alcohol solution first,and then to separate the mixed alcohol components using distillation technology.This paper reports the whole process simulation of the pervaporation-distillation integrated process,and compared with traditional extractive distillation process.The pervaporation-distillation integrated process greatly simplifies the mixed alcohol recovery process.The overall energy consumption could be reduced by 30%.Based to this process design,cooperating with Shanxi Yanchang Petroleum (group ) Co., Ltd, we built the first industrial demonstration unit of pervaporation-distillation integrated process for recovery of mixed alcohols from F-T waste water with a capacity of 1000t/a.关键词
