The Simulate Calculation for the Separation of Ethanol in azeotrope

azeotrope;Extractive distillation;SimulationSeparation process of ethyl-acetate ethanol water with extractive distillation method was simulated by computer soft Aspen Plus. the influences of stage number, feed stage, solvent quantities, reflux ratio, top product on the extractive distillation were simulated and discussed. The obtained results is very important and usefull to industry application.
