The present invention relates to processes to remove butanol and other product alcohols from a fermentation broth employing vacuum vaporization.

Process to remove product alcohols from fermentation broth

The invention relates to a method for producing butanol through microbial fermentation, in which the butanol product is removed by extraction into a water immiscible organic extractant during the fermentation. The invention also relates to a method for producing butanol through microbial fermentation, in which the butanol product is removed during the fermentation by extraction into a water-immiscible extractant composition. The invention further relates to compositions comprising a solution of butanol in a water immiscible organic extractant composition.

Method for producing butanol using extractive fermentation

Methods of producing renewable materials may include consuming a fermentation feedstock with a fermentation organism to produce a renewable material in fermentation broth; water may then be separated from the feedstock or broth using one or more phase separations, or the renewable material may be concentrated from the feedstock or broth using one or more phase separations. Methods of producing biofuel components may include consuming a lignocellulosic or sugar fermentation feedstock with a fermentation organism to produce either ethanol or butanol in fermentation broth; cooling the feedstock or broth to solidify at least some water therein; and separating the solidified water from the feedstock or broth using a solid-liquid phase separation.
