Aspen Plus - Pressure Swing Distillation to Separate Ethanol Water Mixture

[@willynbintiyanam4942]

Can i use pressure swing to separate ethanol & ethyl acetate? The desired product is at least 99.7% purity of ethyl acetate.

Could you please explain how to determine the pressure of HP column?

8:33 ethanol-water mole ratio 20:80
26:24 mole-frac value ethanol 0.8 water 0.2
It shouldn't be mole frac 0.2 ethanol and 0.8 water?

I think it is a mistake in the design problem..because my explanation is based on feed 80:20 EtOH:water..but anyway, the concept is still the same...
