NOVELTY - Integrated facility (10) to coproduce ethanol and biodiesel fuel using corn as a feedstock, comprises: an ethanol plant (12) operable to produce ethanol and a corn oil product from an ethanol-containing beer; a biodiesel plant (14) comprising a reactor assembly operably coupled with the ethanol plant to receive at least some corn oil product from the ethanol plant, and to react the corn oil with alcohol to produce the biodiesel fuel and one or more by-products consisting of e.g. ethanol; and a structure for transferring at least one of the by-products to the ethanol plant for distillation.    USE - The integrated facility is useful for the co-production of ethanol and biodiesel fuel using corn as a feedstock (claimed).    ADVANTAGE - The integrated facility provides the co-production of ethanol and biodiesel fuel in combined facilities having both the ethanol plant and biodiesel plant, where the plants are located in close proximity allowing various products and by-products from each plant to be easily transferred to the other plant to increase the efficiency of the overall, dual-plant facility.    DETAILED DESCRIPTION - Integrated facility (10) for the co-production of ethanol and biodiesel fuel using corn as a feedstock, comprises: an ethanol plant (12) operable to produce ethanol and a corn oil product from an ethanol-containing beer; a biodiesel plant (14) comprising a reactor assembly operably coupled with the ethanol plant to receive at least some corn oil product from the ethanol plant, and to react the corn oil with alcohol to produce the biodiesel fuel and one or more by-products consisting of methanol, ethanol and/or glycerol; and a structure for transferring at least one of the by-products to the ethanol plant for distillation within a distillation apparatus or mixing with a stillage stream of the distillation apparatus undergoing concentration within the ethanol plant. The ethanol-containing beer is contained within a beer well (16). The beer well generates a gaseous overhead comprising carbon dioxide and at least one of the by-products, in gaseous form, is directed from the biodiesel plant to the ethanol plant for the combination with the beer well overhead. The distillation apparatus is operable to create whole stillage. The ethanol plant further comprises a separation assembly operable to generate a thin stillage stream from the whole stillage, and an evaporator apparatus operable to separate the corn oil product from the thin stillage stream and to generate a steam overhead. At least one of the by-product from the biodiesel plant, in gaseous form, is mixed with the overhead steam (22).
