Abstract
Abstract Experimental data and simulations in Aspen Plus® for the batch distillation process were obtained from an ethanol/water mixture. The simulation was carried out in order to verify the effectiveness of the calculations for the batch distillation process for recovering ethanol, using a plate column. The experimental data were taken from a packed batch distillation column. The separation of ethanol/water mixture was studied at different reflux ratios. The ethanol was quantified through a gas chromatography analyses. The simulation and the experimental data were performed considering the ethanol concentration in the wine that comes from the sugarcane fermentation. It was verified that the higher ethanol concentration was obtained in one hour of distillation and the accumulate ethanol concentration was above to 80% (mole) when operated at constant reflux. So, it is possible to obtain high yields and concentrations of ethanol in a short time.
