Investigation of acetic acid dehydration by various methods

Résumé

Some separation methods for acetic acid dehydration, such as azeotropic distillation, extractive distillation and hybrid extraction/distillation process (HEDP) are investigated and further analyzed. In order to optimize the separation process, different separation agents were investigated. The phase equilibria (vapor-liquid and vapor-liquid-liquid) of the ternary system acetic acid/water/separating agent are analyzed in order to choose an appropriate thermodynamic model suitable for the simulation of the system. The results show that the azeotropic distillation is the most undesirable dehydration method among the three separation processes investigated. Almost similar results are obtained using the extractive distillation and HEDP. The latter is energetically more favorable, but the extractive distillation requires less equipment and control operations costs. Therefore, HEDP using methyl tert-butyl ether as an extraction agent is the most promising separation method for the system studied.
