INTEGRATED ETHANOL AND RENEWABLE DIESEL FACILITY

摘要

An integrated facility for the co-production of ethanol and renewable diesel fuel is provided. Corn oil, an ethanol production by-product, is utilized as a feedstock for a renewable diesel plant operating within the same general facility as the corn ethanol plant. By-products of the renewable diesel plant, such as fuel gas, steam, and/or naphtha, can be utilized in various parts of the ethanol plant to increase the operating efficiency thereof.

1. An integrated process for the co-production of ethanol and renewable diesel fuel comprising:
distilling an ethanol-containing beer within distillation apparatus of an ethanol plant to produce an ethanol-rich overhead stream and a solids-containing, whole stillage stream; recovering a corn oil product from said ethanol plant, and directing a stream of said corn oil product to a renewable diesel plant; and reacting said corn oil product stream received from said ethanol plant with hydrogen in a reaction system of said renewable diesel plant to produce a mixture of reaction products comprising renewable diesel fuel, fuel gas, and naphtha.
