In order to explore a novel process of high efficiency and energy saving for separating binary azeotrope ethanol-dimethyl carbonate(DMC),the method of extractive dividing wall column is adopted to separate the system,and the sepearation process is studied by simulating and optimizing.The major contents and results show as below:Firstly,Aspen Plus software is used to establish five kinds of extractive distillation processes for separating ethanol-DMC,and these processes are conventional double-column extract...
