Artigo:

Fermentation is the main step in bioethanol production. The major fermentation problems are the yeast inhibition when high ethanol concentrations are reached, and the high amounts of water added to the process. One way to overcome these problems is to couple fermentation to a continuous process removal, or known as in situ removal techniques. Such techniques allow the use of high sugar concentrations in the broth, keeping ethanol concentration in acceptable ranges to microorganism metabolism. Gas stripping in situ removal presents itself as a simple technique that requires no membrane or expensive chemicals and easy to integrate with fermentation process. In this work, the simulation of a gas stripping fermentation process was carried out using ASPEN PLUS
