| Separation of binary amalgamation of Acetone and Chloroform is not possible by ordinary distillation methods due to the existence of maximum boiling azeotrope. In this study, Pressure swing distillation (PSD) and Extractive distillation (ED) have been employed to separate this mixture. The trouble is the considerable energy consumption by distillation towers. In this article, feed splitting approach has been used for heat integration of the process. In addition, exergy analysis has been used in order to achieve a more precise evaluation and more appropriate comparison between the processes. The results have demonstrated that PSD is not a practical and effective approach to separate this mixture, since the azeotropic point does not change with the pressure fluctuations exerted in this process. Furthermore, according to the obtained results, ED process which is including feed splitting approach has abated the amount of hot utility, cold utility and exergy loss by 19.28%, 19.62% and 65% respectively. | ||
