Title: Mathematical process modeling for EA-EtOH separation by vacuum batch extractive distillation
Abstract: Vacuum batch extractive distillation is a potential technology for the separation of compounds with close boiling point and azeotropic mixtures.By using N,N-dimethylmethanamide(DMF)as a single extractive solvent and the mixture of DMF and dimethyl sulfoxide(DMSO)as a mixed solvent,the vacuum batch extractive distillation process for ethyl acetate-ethanol separation was simulated by a constant molar holdup model.The mathematical model is a group of stiff equations and was resolved by the pursuit method.The simulation agreed well with experiment results.The simulation results illustrated that vacuum operation could intensify the batch extractive distillation process.
