Modeling of Technological Processes for a Rectification Plant in Second-Generation Bioethanol Production

The article deals with the recent developments in fuel industry, considering permanent increasing requirements for quality and environmental safety. work aims to study various technological modes at rectification unit produce bioethanol from lignocellulosic biomass. main goals are solve applied scientific problems of rational designing optimization obtain boundaries energy consumption ensure sufficient a consumer. Recent approaches numerical simulation chemical processes were operating optimize parameters. plant model was designed modules that allow us simulate efficiently accurately all primary units equipment. methodology based on activity coefficient UNIFAC phase equilibrium applied. As result, mixture 74% 9% impurities obtained brew column. In epuration column, 46% 2.2% bottoms. Finally, alcohol mass fraction distillate 96.9% 2.7% reached. results can be technologies corresponding biofuel plants.
