Comparative study of Heat Pump Assisted Distillation Column and Its Application for Pressure Swing Distillation Process

Homogeneous azeotropic pressure swing distillation: continuous and batch process

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 distillat...

Simulated Heat Integration Study of Reactive Distillation Column for Ethanol Synthesis

Ethanol is largely used as a solvent in the synthesis of varnishes and perfumes. It is also used as a preservative for biological products, fuel, and gasoline additives. Anethanol-water mixture, normally obtained by fractional distillation</span...

New 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...

Investigation of Heat Loss in Ethanol-Water Distillation Column with Direct Vapour Recompression Heat Pump

Vapour recompression system has been used to enhance reduction in energy consumption and improvement in energy effectiveness of distillation columns. However, the effects of certain parameters have not been taken into consideration. One of such parameters is the column heat loss which has either been assumed to be a certain percent of reboiler heat transfer or negligible. The purpose of this st...
