摘要： This disclosure describes processes for using a single cellulosic feedstock or a combination of two or more different cellulosic feedstocks with a starch component to produce a fermented product. The process includes separating the components of the cellulosic feedstocks with fractionation, pretreating a component with wet fractionation with chemicals, hydrolysis and fermenta-tion of the pretreated feedstock(s) to produce cellulosic biofuel. The process may include combining the cellulosic feedstock(s) with other components to a cook and/or a fermentation process, distilling and dehydrating the combined components to produce the biofuel. The process may also include producing a whole stillage stream from the feedstock(s) and mechanically processing the whole stillage stream to produce a high-value protein animal feed.

摘要： The present invention is for the production of fuel grade alcohol, specifically ethanol. A steam dryer is used to dry the solid byproduct into usable animal feed. The steam dryer typically contains less than 6% air in its exhaust stream is directed to the bottoms of one or more distillation columns to heat the distillation column and scrub the exhaust stream simultaneously. The elimination of a thermal oxidizer and the efficient use of the energy in the exhaust stream provide considerable cost savings for an alcohol production plant.

摘要： The present invention relates to a method for purifying an aqueous solution of fermentation alcohol to give anhydrous alcohol, wherein a mash column is controlled such a manner that an alcohol concentration of an alcohol/water mixed vapor distilled from a mash column is less than 50% by weight and a reflux amount of a condensate to a distillation column is controlled such a manner that an alcohol concentration of an alcohol/water mixed vapor that is distilled from the distillation column is 65 to 85% by weight. According to the present method, the purification for obtaining an anhydrous alcohol from an aqueous solution of a fermentation alcohol with the use of a mash column, a distillation column, an evaporator and a membrane separator can be more conveniently carried out with an extremely high energy efficiency as the whole process.

摘要： A distillation process for the production of dehydrated ethanol from dilute aqueous solutions of ethanol characterized in that the distillation is performed in a two-column system wherein the first column--for rectification--is operated under such a pressure that the second column--for dehydration--is heated exclusively with the vapors of the first column; in the first column the concentration of the dilute aqueous ethanol is effected to an ethanol concentration below the composition of the binary ethanol-water azeotrope; the separation of water is effected from the lower layer of the condensed head product of the second column; the separation of impurities and entrainers, having a lower boiling point than ethanol, is effected at the head of the first column and that of impurities, having a higher boiling point, above the feed point of the dilute aqueous solution in the first column; and, in the second column, the dehydration is effected by means of entrainers, with the addition of a fuel component or fuel, to which the ethanol is to be added, if required, while separating the aqueous phase as a head product.

摘要： An improved distillation method is provided for obtaining motor fuel grade anhydrous ethanol from fermentation or synthetic feedstocks. A three tower system is used comprising a stripper-rectifier tower in which the dilute feedstock is converted to a concentrated ethanol stream, a dehydrating tower in which water is removed from the concentrated ethanol stream by azeotropic distillation, and a stripper tower for recovering the azeotropic agent. The invention effects substantial energy savings by utilizing the heat content of the overhead vapors from the stripper-rectifier tower to supply the heat required for the dehydrating and stripper towers and by preheating the feedstock in stages utilizing the heat content of the overhead vapors from the dehydrating and stripper towers, the heat content of the overhead vapors from the stripper-rectifier tower and the heat content of the bottoms from the stripper-rectifier tower. Provision is also made for separately removing lower boiling and higher boiling impurities from the stripper-rectifier tower which may be blended into the anhydrous ethanol product from the dehydrating tower.
