Economic and process optimization of ethanol production by extractive fermentation

Abstract

This report demonstrates by computer simulation the economic advantages of extractive fermentation on an industrial scale compared to the best alternative technology currently available. The simulations were based on a plant capacity of 100 x 10 6 L/y of azeotropic ethanol. The simulation results were verified with a fully integrated, computer controlled extractive fermentation process demonstration unit based around a 7 L fermentor operated with a synthetic glucose medium and using Saccharomyces cerevisiae. The system was also operated with natural substrates (blackstrap molasses and grain hydrolyzate). Preliminary tests with the organism Zymomonas mobilis were also carried out under extractive fermentation conditions.
