In this study,computer simulations were performed to obtain highly pure Tetrahydrofuran (THF) with over 99.9 mole % from mixture of THF and water.A pressure swing distillation (PSD) process was used since the azeotropic point between THF and water can be varied with pressure.A commercial process simulator,PRO/II with PROVISION release 8.3,was used for the simulation studies.The Wilson liquid activity coefficient model was used to simulate the low pressure column and the Peng-Robinson equation of state model was added to correct the vapor phase non-idealities for the modeling of the high pressure column.The most optimal reflux ratios and the most optimal feed stage locations that could minimize the total reboiler heat duties were determined.
