Abstract
65538 Ethanol is an environmentally friendly oxygen additive for fuel. However, during the fermentation process, the build up of ethanol negatively impacts the fermentation microorganism, thereby decreasing productivity and increasing energy consumption. Research has shown that ethanol could be continuously removed from the fermentation media with non-porous pervaporation membranes, but viscosity and fouling effects make this solution impractical. This project will use a high-flux, low-selectivity pervaporation membrane to remove ethanol from a continuously operated fermentor. The membrane will be activated with low frequency acoustic energy to eliminate mass transfer resistance and intensify the process. Phase I will demonstrate that the technology will facilitate the removal of ethanol from an active fermentation broth. The ability to maintain a high flux rate for ethanol and water without damaging yeast cells will be evaluated, and the economic feasibility will benchmarked against industry standards. Commercial Applications and Other Benefits as described by the awardee: This technology should enable existing fermentors to fully implement modern separation methods. Lower ethanol production costs and increased productivity should result.
