Homogeneous azeotropic pressure swing distillation: continuous and batch process
نویسندگان
چکیده
The separation of a binary homogeneous azeotropic mixture using pressure swing distillation will be analysed on the example of acetonitrile/water. Two different processes are considered: the continuous heatand mass-integrated process and the inverted batch process. For both processes a model is developed and experimental data are given. In the paper the potential of the pressure swing distillation for the separation of binary homogenous azeotropic mixtures will be demonstrated, in particular the process performance is investigated and application aspects for the continuous as well as the inverted batch process are discussed.

BK1064-ch68_R2_250706 PRESSURE SWING BATCH DISTILLATION FOR HOMOGENOUS AZEOTROPIC SEPARATION
The separation of the homogeneous azeotropic mixture acetonitrile/water by pressure swing distillation (PSD) is considered. The PSD is operated as a discontinuous (batch) process and two batch modes, regular and inverted, are considered. The processes are analysed, aspects as to which batch mode should be preferred are discussed, and a dynamic model for both batch PSD processes is formulated. T...
متن کاملNew Column Configurations for Pressure Swing Batch Distillation Rigorous Simulation Calculations
The pressure swing distillation in different batch column configurations is investigated by rigorous simulation calculations. The calculations are made by a professional flow-sheet simulator for the separation of a minimum (ethanol–toluene) and a maximum boiling (water– ethylene-diamine) azeotropic mixture. Besides studying the well known configurations (rectifier, stripper) we also investigate...

This paper addresses the internal heat integration to the pressure-swing distillation process used in the separation of binary azeotrope mixture. A general procedure is suggested and illustrated through the separation of an binary mixture, which forms pressure-sensitive minimum-boiling azeotropes. Comparisons are made between the conventional and the internally heat integration processes. It is...
متن کاملSeparation of tetrahydrofuran and water using pressure swing distillation: Modeling and optimization
−Computer simulations were performed to obtain highly pure tetrahydrofuran (THF) with over 99.9 mole% from the mixture of THF and water. Pressure swing distillation (PSD) was used since the azeotropic point between tetrahydrofuran 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 activ...
