ABSTRACT:
Water soluble oxygenated hydrocarbons produced by microbial fermentation, e.g., ethanol, butanol, acetone, etc., are conveniently and economically recovered with a minimum expenditure of energy by passing heated by-product carbon dioxide gas through at least a portion of the fermentation medium to simultaneously vaporize and carry off oxygenated hydrocarbon fermentation product dissolved therein and reduce the temperature of the fermentation medium to a level conducive to maximum oxygenated hydrocarbon production. The vaporized oxygenated hydrocarbon fermentation product is separated from the carbon dioxide gas in a scrubbing unit and the resulting aqueous solution of product is concentrated, if desired, by distillation.
