Publication number: 20240033652Abstract: 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.Type: ApplicationFiled: October 9, 2023Publication date: February 1, 2024Applicant: Whitefox Technologies LimitedInventors: Virginia Andrade, Jin Ming ZHOU, Stephan Rudiger BLUM

Patent number: 8338651Abstract: 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.Type: GrantFiled: July 11, 2008Date of Patent: December 25, 2012Assignee: Solvay Fluor GmbHInventors: Ercan Uenveren, Erhard Kemnitz, Stephan Rudiger, Anton Dimitrov, Johannes Eicher
