TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The distilling step creates a whole stillage product. The process comprises recovering the corn oil product from the whole stillage. The beer is contained within a beer well (16), which generates a gaseous overhead comprising carbon dioxide. The transferring step comprises: directing the by-products in gaseous form for combination with the beer well overhead; condensing the by-products to generate a condensed by-product comprising ethanol and/or methanol, and directing the condensed by-product for mixture with the beer; transferring the by-products in gaseous form for mixture with the evaporator steam overhead; transferring at least some of the liquid crude glycerol to the ethanol plant for distillation within the distillation apparatus or mixing with the stillage stream of the distillation apparatus; transferring the liquid crude glycerol for mixture with the beer; and transferring the condensed by-product for mixture with the heated corn/water slurry. The combined beer well overhead is passed through a carbon dioxide scrubber to separate the carbon dioxide and create a water stream comprising the by-products. The water stream is employed to supply at least part of the water for the generation of a heated corn/water slurry within the ethanol plant. The whole stillage product is treated to generate a thin stillage. The corn oil product is separated from the thin stillage product by evaporation of the thin stillage in a multiple-effect evaporator comprising first and second effects to generate the corn oil product and an evaporator steam overhead. The reaction step generates a supply of liquid crude glycerol. The step of transferring the liquid crude glycerol comprises mixing the crude glycerol with a concentrated thin stillage product from the first effect. The ethanol plant operation includes generating a heated corn/water slurry. Preferred Components: The alcohol comprises ethanol, and/or methanol. The biodiesel fuel plant produces a biodiesel distillation bottoms stream comprising one or more members consisting of mono-, di-, and triglycerides. The distillation bottoms stream is transferred to the ethanol plant.
