Simulation and Optimization of the Vacuum Extractive Fermentation Coupled to an Absorption Column for Bioethanol Production Using a High Biomass Concentration

摘要

The ethyl alcohol has positive characteristics for being used as fuel in large scale:rnrelatively low cost, less polluters and can be produced from renewable matrix byrnfermentation of vegetable source products. By means of process simulation usingrnASPEN PLUS? V.7, it was evaluated a configuration based on the extractivernfermentation vacuum concept coupled to an adsorption column, in which, the alcohol isrnextracted from fermentation environment while it is produced, as a result, a morernproductive process is obtained due to a decrease in the inhibition effect on thernmicroorganism caused by the ethanol and at the same time, this configuration allowsrnusing a more concentrated must. It was found that the proposed configuration provides arnbigger production and recovery of the ethanol contributing to the improvement andrnintensification of the process.
