heal.abstract	The use of near-anhydrous ethanol, obtained from fermentation products through low pressure distillation, as a gasoline additive is examined. To this purpose, a reliable model for predicting the azeotropic composition of an ethanol-water mixture as a function of the pressure is presented. It is developed by considering the available thermodynamic consistent experimental data and using the Wilson and the Virial equations for the liquid- and vapor-phase nonideality, respectively. It is concluded that, for an area with no extremely cold winters-minimum ambient temperature - 20°C-alcohol with 96.5% (wt) purity can be used in a %/lo (vol) gasohol mixture. Such an alcohol can be produced with a single distillation column operating at 140 mmHg pressure with an energy consumption of 5150 kJ/kg of product; or with a system of two columns with lower energy consumption but higher capita1 cost. These energy consumptions are very sensitive to the accuracy of the predicted azeotropic composition at the operating pressures. © 1995 by Marcel Dekker, Inc.	en
