A Study on the Pressure-Swing Distillation of Ethanol-n-Heptane Azeotrope Noh, Sang Gyun;
In the present study, modelling and optimization of ethanol-n-heptane separation process were performed using pressure-swing distillation. The pressure-swing distillation process optimization was performed to obtain high purity ethanol and high purity n-heptane into a low-high pressure columns configuration and a high-low pressure columns configuration. The results of pressure-swing distillation process simulation and optimization using high-low pressure column configuration showed a reduced total reboiler heat duty at 5.8% which confirmed a more economical energy consumption.
