Entrainer Screening, Vapor–Liquid Equilibrium Measurement, and Extractive Distillation Simulation for the Ethyl Propionate–Ethanol Azeotropic System
Listed in ZivaHub
The separation of ethyl propionate (EtPr) from the EtPr-ethanol (EtOH) azeotropic system is a challenging industrial problem.
Description
Herein, 252 ionic liquids (ILs) were screened via COSMO-RS theory, and tributylmethylammonium acetate ([N<sub>4441</sub>][Ac]) was selected as the optimal extractive distillation entrainer by evaluating selectivity and infinite-dilution solvent capacity. Vapor–liquid equilibrium (VLE) data of the EtPr (1) + EtOH (2) + [N<sub>4441</sub>][Ac] (3) system were measured at 101.3 kPa.
The added [N<sub>4441</sub>][Ac] effectively improved the relative volatility of EtPr and completely eliminated the azeotrope at an IL mole fraction of 8%. The NRTL model provided accurate data correlation with reliable thermodynamic consistency. An optimized extractive distillation process was established via Aspen Plus V11 to obtain high-purity EtPr and EtOH.

Economic analysis shows that the proposed process reduces total annual cost (TAC) by 18.75% and 38.83% compared with ethylene glycol-based extractive distillation and vacuum distillation, respectively.
