Abstract
Extractive fermentation is a processing strategy in which reaction and recovery occur simultaneously in a fermentation vessel through the use of a water-immiscible solvent which selectively removes an inhibitory product. An ethanol-extractive fermentation process has been developed, incorporating continuous operation and the ability to ferment concentrated feedstocks. A detailed economic assessment of this process is provided relative to current technology for an annual capacity of 100 million litres of ethanol. Extractive fermentation provides significant economic advantages for both grass roots and retrofitted plants. Total production costs are estimated at 45{cents}/l for a conventional plant and 29.4{cents}/l for a retrofitted plant. The main cost saving achievable by extractive fermentation is in energy, used for evaporation and drying, since the process uses significantly less water in its conversion of concentrated feedstocks. Producing anhydrous ethanol without distillation is also a prospect. 15 refs., 5 fig., 10 tabs.
