The pressure swing distillation in different batch column configurations isudinvestigated by rigorous simulation calculations. The calculations are made by audprofessional flow-sheet simulator for the separation of a minimum (ethanol–toluene) anduda maximum boiling (water– ethylene-diamine) azeotropic mixture. Besides studying theudwell known configurations (rectifier, stripper) we also investigate two noveludconfigurations such as double column batch rectifier and double column batch stripper.udThe alternate application of a batch rectifier and a batch stripper is also studied. Theuddifferent column configurations are compared.
