GHG Emissions and Energy Minimization using Heat Integrated Pressure Swing Distillation Sequence (HiPSDS) for the Separation of Azeotropic Mixture
نویسندگان
چکیده
The present work elaborates the process design methodology for the evaluation of the distillation systems based on the economic, exergetic and environmental point of view, the greenhouse gas (GHG) emissions. The methodology proposes the Heat Integrated Pressure Swing Distillation Sequence (HiPSDS) is economic and reduces the GHG emissions than the conventional Extractive Distillation Sequence (EDS) and the Pressure Swing Distillation Sequence (PSDS) for the case study of isobutyl alcohol and isobutyl acetate with the solvents for EDS and with low pressure variations for PSDS and HiPSDS. The study demonstrates that the exergy analysis can predict the results of the economic and environmental evaluation associated with the process design.

Separation of Binary mixture using Pressure Swing Distillation with Heat Integration
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...

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...
