TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: In the process (M1), the alkyl acetate solvent occurs prior to fermentation or post fermentation in the ethanol production process and is applied to at least one byproduct of the fermentation process. The removed alkyl acetate solvent is recycled into the process. The deoiled second phase is concentrated by removal of a percentage of water or to produce a filter cake. An ethanol azeotrope is applied to the filter cake to dissolve the remaining water and drying deoiled remaining solids by the application of carbon dioxide. The ethanol carried by the carbon dioxide from the drying step is removed from the carbon dioxide via a condenser and the carbon dioxide is recycled back to the production process. The corn-based product comprises milled corn, thick stillage, and distillers wet grain. The deoiled corn-based product comprises deoiled distillers wet grains and is concentrated by removal of a percentage of water and where syngas is produced from the concentrated deoiled distillers wet grain using a pressurized gasifier. The the byproduct comprises distillers dried grains with solubles. Preferred Components: The alkyl acetate is an azeotrope. Preferred System: The system for removing oil from corn products prior to fermentation in ethanol production facility comprises hammermill for reducing whole corn to a milled corn and producing an output stream of milled corn; extractor containing a solvent and in communication with the output stream from the hammermill capable blending of the milled corn with the solvent to form a solvent mixture and capable of producing a solvent mixture stream; and solvent stripper in operable communication with an output solvent mixture stream from the extractor, where the solvent stripper is capable of removing solvent from the solvent mixture to form a deoiled milled corn stream, and the solvent stripper further is in operable communication with the extractor to provide at least a portion of the solvent stream to the extractor and in operable communication with a fermentor to provide a deoiled milled corn stream to the fermentor for the production of ethanol. The system for removing oil from corn product post fermentation in ethanol production facility comprises extractor containing solvent and in operable communication with fermentor, where the extractor is capable of receipt of an output thick stillage stream from the fermentor and forming a solvent mixture; phase settler in operable communication with the extractor for receipt of the solvent mixture, and enabling the separation of deoiled corn product phase from an oil in solvent phase; distillation assembly in operable communication with the phase settler for receipt of an oil in solvent phase stream, where the distillation assembly is capable of separating the oil from the solvent, and is in operable communication with the extractor to provide at least a portion of the solvent to the extractor; and reboiler desorption unit operably attached to the phase settler for receipt of a deoiled corn product phase stream, where the reboiler desorption unit is capable of removal of solvent remaining in the deoiled corn product phase, and is in operable communication with the extractor to provide at least a portion of the solvent stream to the extractor. The system further comprises a filtration device operably attached to the reboiler desorption unit for receipt of the deoiled corn product stream. The filtration device is capable of separating the deoiled thick stillage into an oil free distillers wet grain and an oil free thin stillage and in communication with a membrane for water removal and a drying device for producing an oil free distillers dried grain with solubles. The The system also comprises a water removal device in operable communication with the reboiler desorption unit for receipt of the deoiled corn product stream, where the water removal device is capable of removal of a percentage of water from the deoiled corn product stream. The system additionally comprises a combustion device in operable communication with the water removal device to receive a deoiled distillers wet grain corn product stream, where the combustion device is capable of generating energy output from the deoiled corn product stream. In the system an optimum moisture level (preferably 30 wt.%) in the deoiled corn product stream for combustion is obtained. EXAMPLE - No suitable example given.
