SIMULACIÓN DEL PROCESO DE DESHIDRATACIÓN DE ETANOL UTILIZANDO EL SOFTWARE ASPEN-HYSYS V3.2

Abstract

This project is based on the simulation of ethanol dehydration process using ASPEN-HYSYS software version 3.2. The process consists of two distillation columns, a sub-diagram and phase separators. Obtaining anhydrous ethanol is made from a blend of ethanol in water with a purity of azeotropic concentration limit of 95% by weight using benzene as a solvent. The simulation is implemented with real data from the Central Rum Distillery Agustin Rodriguez, Villa Clara. Extractive distillation using glycerol alternative is proposed. Anhydrous ethanol is obtained with a value of 0.9974 mass fraction in the distillation with benzene as the extraction is reached only 0.9951 in the same units. Case studies are performed for the process with real data using benzene and the proposed alternative using glycerol. Profiles of temperature, pressure and components in the azeotropic distillation are verified.
