摘　　要：利用四氢呋喃(THF)-水溶液的共沸组成和温度随压力改变的特性,采用常压塔-加压塔双塔差压的精馏系统对四氢呋喃进行分离提纯。采用AspenPlus软件,对四氢呋喃和水溶液二元体系的工艺分离过程进行模拟。重点对加压塔是否采用回收塔进行了物料衡算,精馏塔配置及能量衡算的对比分析。通过模拟计算,可以让学生较为深刻的理解差压精馏过程,有利于学生工程实践能力的培养。As the azeotropic temperature and compositions of THF-Water changes with the pressure,a distillation process at different pressure with a atmospheric column and a pressurized column was established to purification the THF.Aspen plus is used to simulate this purification process of THF-Water binary system.Material balance,distillation column configuration and energy balance analysis were highlighted the differences of pressure tower using recovery tower or not.Through the simulation calculation,students can have a deeper understanding of the differential pressure distillation process,which is conducive to the development of students'engineering practice ability.
