NOVELTY - The method involves reacting a maize oil product from an ethanol plant (12) with hydrogen in a reaction system (106) of a renewable diesel plant (14) to produce mixture of reaction products that comprise diesel fuel, fuel gas and naphtha. The reaction products are directed to a distillation system (116) of the diesel plant for separation of the reaction products into a renewable diesel fuel stream, a fuel gas stream and a naphtha stream. A portion of the fuel gas stream is combusted within fuel gas-combusting devices that are located within or utilized during operation of the ethanol plant.    USE - Integrated method for facilitating co-production of ethanol and renewable diesel fuel for an industrial application. Uses include but are not limited to soap, paint, rust-proofing material, ink, textile and insecticide.    ADVANTAGE - The method enables co-locating renewable diesel and maize ethanol production facilities in an efficient manner. The method enables reducing transportation costs through integration of different by-products of renewable diesel production within the maize ethanol production facility. The method enables combining steam from stream with steam produced by a steam generator, so that a portion of the steam generated within the renewable diesel plant is utilized within the ethanol plant, thus decreasing the need for steam generation with external energy input, while increasing operating efficiency of the ethanol plant.    DETAILED DESCRIPTION - The fuel gas-combusting device is selected from a group consisting of thermal oxidizer burner, cake dryer air heater, gas turbine and boiler. An INDEPENDENT CLAIM is also included for an integrated facility for facilitating co-production of ethanol and renewable diesel fuel.
