In view of the increasing environmental concern, the use of renewable and less pollutant energy sources has been encouraged. In this context, bioethanol has been used as fuel in the anhydrous form, blended with gasoline. In this work, simulations of the extractive distillation process in anhydrous bioethanol production were carried out in Aspen Plus (R) using nonequilibrium stage model and equilibrium stage model with Barros and Wolf efficiency correlations for plate and component. Equilibrium stage model with plate efficiency determined through Barros and Wolf efficiency correlation showed a satisfactory agreement with results predicted by the nonequilibrium stage model for anhydrous bioethanol production process.
