基于Aspen plus异丙醚-异丙醇-水的连续萃取分离

Continuous Extraction and Separation Based on Aspen for the Water of the ISO-Propylene Alcohol-Water

选用乙二醇(EG)为萃取剂,用Aspen Plus化工模拟软件中的Radfrac单元操作模块,采用UNIFAC物性计算方法,通过优化各参数,在适宜操作条件下,塔顶可以得到高纯度的二异丙醚、异丙醇产品。

Radfrac（ EG） was used as the extraction agent,and the unit operation module of Plus Aspen chemical simulation software was used to calculate the high purity of two ISO propylene oxide and ISO alcohol by using UNIFAC method.
