  • Process for continuous solvent production
    Publication number: 20050089979
    Abstract: A continuous process for production of solvents, particularly acetone-butanol-ethanol (ABE) using fermentation of solventogenic microorganisms and gas stripping is provided. The solventogenic microorganisms are inoculated in a nutrient medium containing assimilable carbohydrates (substrate) and optional other additives. Control of the solventogenic microorganism concentration in the fermentor (cell concentration) and the assimilable carbohydrate concentration in the fermentor, along with removal of solvents formed results in a continuous process for production of solvents.
