Abstract The extractive distillation process exploits the capacity of some chemicals to alter the relative volatility between the components of a mixture. In this way, a third component (called entrainer) may be added to an azeotropic binary mixture to break the azeotrope. This paper discusses the potential use of ethylene glycol as entrainer in a 1-propanol dehydration process by extractive distillation. First, the present work focuses on the acquisition of isobaric vapor–liquid equilibrium data of the ternary system 1-propanol + water + ethylene glycol system and the binaries systems 1-propanol + ethylene glycol and water + ethylene glycol. All measurements were done at 101.3 kPa. The experimental data were correlated by the Wilson, NRTL and UNIQUAC local composition models in order to obtain a set of thermodynamic parameters. Finally, the extractive distillation process was simulated and later economically optimized with the aid of commercial software (Aspen Hysys ® ) using the previously obtained parameters of the NRTL model.
