heat integration of extractive distillation for separation of maximum boiling azeotropic mixture

Separation of binary mixture of acetone and chloroform is not possible by the ordinary methods of distillation due to azeotropic point existence. in this paper, extractive distillation and pressure swing distillation methods have been used to separate the mixture of acetone and chloroform and the results have been compared. the issue that we struggle with is consuming a noticeable amount of energy by distillation columns. in this paper, feed splitting has been used as the method of heat integration. the results have shown the fact that pressure swing distillation is unable to reach the purity of 99% for the products. on the other hand, extractive distillation accompanied by feed splitting method has shown a 19.31% and 19.62% decrease in the amount of hot utility and cold utility respectively.
