TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: In process (p1), the ester forming conditions comprise acid catalyzed esterification, or base catalyzed transesterification. In first step of process (p2), extractant is introduced into the fermentation broth during fermentation, and contacted with at least a portion of the fermentation broth that has been removed from fermentation. The process (p2) involves fermenting carbohydrate in an aqueous fermentation broth to produce alkanol, where the fermentation broth containing glycerides and solids; subjecting at least a portion of the fermentation broth to distillation conditions to remove at least a portion of the alkanol and provide a whole stillage; contacting the whole stillage with extractant comprising biodiesel to provide an extract containing glycerides and an aqueous phase having a reduced concentration of glycerides and solids; phase separating the whole stillage to provide a solids-containing phase and at least one liquid phase or a thin stillage; phase separating the extract and the aqueous phase; subjecting at least a portion of the extract in the presence of lower alkanol to ester forming conditions to convert glycerides to biodiesel and coproduce glycerin; and recycling a portion of the biodiesel to third step as at least a portion of the extractant. The forth and fifth steps of the process (p2) are simultaneously performed. In process (p2), the thin stillage is subjected to evaporation conditions prior to forth step. The phase separation of fifth step involves centrifugation and sufficient biodiesel is provided to avoid undue emulsion formation during separation. After phase separation, the process (p1) also involves contacting the solids with at least one of water and steam under conditions sufficient to remove at least a portion of the residual extract from the solids and provide a wash liquid containing water and extract; and phase separating the wash liquid to provide an extract-containing fraction and an aqueous fraction. In process (p1), the biodiesel is phase separated from glycerin prior to the recycling step. The biomass derived feedstock is derived from a process stream in a process for the production of ethanol by fermentation of carbohydrate, where the process stream contains fermentation broth, distiller grains, or hydrolyzate of carbohydrate. The process stream is a thin stillage after separation of distiller grains. Preferred Components: The biomass derived feedstock is from at least one of rape seed, soybean, cotton seed, safflower seed, castor bean, olive, coconut, palm, corn, canola, jatropha, rice bran, tobacco seed, and fats and oils from animals (preferably milled, ground or flaked soybean).
