| Abstract: | The mixture of ethanol and benzene has a minimum azeotrope. The separation process of ethanol-benzene mixture was studied. Pressure-swing distillation method was adopted to separation ethanol and benzene and the flowsheet was simulated by Aspen Plus with Wilson equation for activity coefficients. Important process parameters are optimized to minimize energy consumption. The process can be used for the design of a industrial plant. |
