  • Publication number: 20250146026
    Abstract: Congener removal in ethanol production may be provided by fermenting a feedstock in a fermentation vessel, yielding a fermentation product including an organic solvent and water, and inert fermentation gases; distilling the fermentation product in a distillation column yielding a first solvent enriched stream; dehydrating the first solvent enriched stream yielding a second solvent enriched stream having a greater concentration of the organic solvent than the first solvent enriched stream and a water enriched solution; and sparging the water enriched solution with the inert fermentation gases in a sparging tank yielding a sparged solution and a vapor including volatile species present in the water enriched solution separated out from the sparged solution.

  • Publication number: 20240033652
    Abstract: The present disclosure provides processes and systems for ethanol production. In one embodiment, a first beer column receives a first portion of a feed mixture including ethanol and water to form a first beer column bottom stream and a first beer column vaporous overhead stream. A beer column receives a second portion of the feed mixture. A first portion of the first beer column bottom stream is forwarded to a first beer column reboiler. A second portion of the first beer column bottom stream is forwarded to a plurality of evaporators. A condensed portion of the first beer column vaporous overhead stream is forwarded to a stripper column. The stripper column forms a feed stream, which is contacted with a separation system, thereby forming a permeate and a retentate. The permeate is forwarded directly to at least one selected from the first beer column and the stripper column.

  • Patent number: 8338651
    Abstract: Halogenated alkenes, especially fluorinated alkenes can be prepared from halogenated and fluorinated alkanes, respectively, by dehydrohalogenation or dehydrofluorination in the presence of a high-surface metal fluoride or oxifluoride. Preferably, trifluoroethylene, pentafluoropropene, tetrafluorobutenes or trifluorobutadiene are prepared. Aluminum fluoride is highly suitable. The metal fluoride or oxifluoride can be applied supported on a carrier.

  • Publication number: 20080135396
    Abstract: A feed stream is fed to a first distillation stage comprising at least one distillation column (stripper) and the distillate from the first distillation stage is fed to a second distillation column (rectifier). The feed stream is sub-divided into two streams and fed to two distillation columns, in such a way that the rectifier maintains a predefined energy balance.
