![]() ![]() The results showed that the ethanol-water mixture dehydration with glycerol as separation agent is efficient from the energy point of view. The effect of molar reflux ratio, solvent-feed ratio, solvent entry and feed stage and solvent entry temperature were evaluated on the chosen restrictions. ![]() Simulation restrictions were ethanol’s molar composition in dehydrator column distillate and the process’s energy consumption. The simulated process involves two distillation columns, a dehydrator and a glycerol recuperation column. Simulations were done on an Aspen Plus process simulator (Aspen Tech version 11.1. The present work approaches the problem of dehydration through simulating azeotropic ethanol extractive distillation using glycerol as separation agent. The tendency throughout the world today is to replace fossil fuels with those having a renewable origin such as ethanol this, in turn, produces a demand for the same and the need for optimising fermentation, treating vinazas and dehydration processes.
