The cost of fuel-grade alcohol made by fermentation is affected by the productivity of the fermentation system, the method of product recovery, and the amount of stillage/wastewater to be treated. Development of a continuous extractive fermentation process, whereby in situ solvent extraction is coupled directly to the fermentation stage, thus transferring the ethanol to an organic phase and reducing the effect of end product inhibition. This results in improved ethanol productivity, decreased product recovery costs, and reduced wastewater treatment costs by virtue of the capability of the system to ferment concentrated feeds. In this paper, experimental data from a working prototype system and computer simulations will be employed to provide the basis for a preliminary economic evaluation of continuous extractive ethanol fermentation with respect to such parameters as ethanol productivity, capital costs and operating costs for plant scale ethanol production.
