Abstract

Acetic acid is recovered from dilute aqueous solutions by extraction followed by azeotropic distillation. The heat required for distillation accounts for the major proportion of the cost of the process. Therefore, the proper selection of the entrainer is of great importance. In this paper, a procedure for preliminary entrainer selection is developed combining the well proved heuristic approaches and the latest developments for the synthesis phase based on residue curve maps and liquid-liquid equilibria plots. The energy requirements for the most promising entrainers are calculated using a commerdal process simulator. It was found that methyl tert-butyl ether is a promising entrainer for the acetic acid dehydration process.
