    摘要： A method and system for distilling alcohol in an alcohol production process is disclosed. The method can include fermenting a mixture of water and milled grain to produce alcohol-laden beer, which can be distilled in a beer column maintained at a subatmospheric pressure to produce a vapor, primarily including alcohol, and whole stillage. Stillage is separated from the whole stillage. Water is evaporated from the separated stillage to produce first-concentrated stillage and first effect steam. Water from the first-concentrated stillage is evaporated with heat from the first effect steam to produce second effect steam. In one embodiment, second effect steam can be used to supply sufficient heat to a side stripper for distilling the alcohol-laden beer. In another embodiment, the method can include generating steam from one or more steam generator to supply sufficient heat to the beer column for distilling the alcohol-laden beer.

    摘要： A process for recovering a volatile carboxylic acid from an aqueous stream comprising same, the process comprising the steps of: (i) steam stripping the carboxylic acid from the aqueous stream, which aqueous stream is produced by a conversion process using a lignocellulosic feedstock as a substrate, the steam stripping comprising contacting the aqueous stream with steam by flowing the aqueous stream and the steam countercurrent to one another, thereby producing a vapor stream comprising vaporized carboxylic acid and steam and a stripped aqueous stream; (ii) extracting the vaporized carboxylic acid with an organic solvent by contacting the vapor stream with the organic solvent to produce (a) a stream comprising the organic solvent and the carboxylic acid and (b) the steam at least substantially depleted of the carboxylic acid, wherein the organic solvent has an atmospheric boiling point of at least about 150° C. and is insoluble in water; (iii) returning the steam from step (ii) to the steam stripping step (step i) to further strip the carboxylic acid from the aqueous stream; and (iv) separating the carboxylic acid from the organic solvent.

    摘要： This invention relates to a process for debittering spent brewer's yeast, aiming at maximal efficiency with minimal impact on yeasts for their further use as live cells. The process consists in bringing a yeast suspension in contact with a surfactant containing unsaturated fatty acids, like Tween 80.RTM. (0.2% to 20% v/v), adjusting pH to 10.0 with NaOH 2N and agitating during 5 minutes at 50 rpm and 50.degree. C. A bitterness reduction of 98% is obtained, without affecting yeast viability or protein content. Furthermore, the debittered yeasts treated with 20% Tween 80.RTM. can be reactivated (viability of 100% and increased production of CO.sub.2) by growing them in a suitable medium for a sufficient time (about two to six hours). These reactivated yeasts have restored biological properties which are expected to allow the use of these spent yeasts in complete or partial replacement of new yeasts in bakery industry and in spirit and beer fabrication. This application for an industrial by-product brings a plus-value by exploiting its biological activity and its nutritional value and furthermore, represents an interesting solution for an environmental problem.

    摘要： Systems and methods for fractionating whole stillage from an ethanol production facility are provided. Whole stillage undergoes a separation of its liquid portion (thin stillage) from the solid portion (fiber cake). In some embodiments, the solids and liquids in whole stillage may be separated utilizing a screening centrifuge. The fiber cake may be dried to generate a high fiber animal feed. The thin stillage may be provided to a three-phase separator for separation into an oil emulsion, an aqueous clarified stillage, and a protein paste. The protein paste may be dried to generate a high protein animal feed with greater than about 45% protein content. The clarified thin stillage is condensed to yield a syrup with greater than around 60% solids. The oil emulsion is subjected to a pH adjustment to liberate the oil from the emulsion, which is then separated.
