Patent number: 4769112Abstract: A method and apparatus for removing water from a liquid mixture of water and ethanol contacts it with liquid carbon dioxide so that the ethanol is preferentially transferred into solution, dries the solution using an adsorbent, and then recovers dry ethanol by distilling off the carbon dioxide. This process is particularly energy efficient especially when it includes a fermentation process to generate the ethanol and uses the carbon dioxide generated during the fermentation as the source of liquid carbon dioxide. In this case the method and apparatus provide an additional product of dry carbon dioxide.Type: GrantFiled: January 20, 1987Date of Patent: September 6, 1988Assignee: United Distillers P.L.C.Inventor: Alfred G.

Patent number: 4347321Abstract: A method and apparatus particularly suitable for the production of alcohol from fermentable substances such as grain. In this method, mash cooking, fermentation, and boiling are carried out sequentially in a single vessel. Boiling produces a first vapor rich in alcohol which is partially condensed to form a liquid condensate and a second vapor which is further enriched in alcohol. The liquid condensate is returned to the vessel and an alcohol product is recovered from the second vapor, preferably without the addition of external heat. Alcohol recovery is effected by passing the second vapor to a second vessel. Vapor from the second vessel is partially condensed to form a third vapor which is still further enriched in alcohol and a liquid condensate which is returned to the second vessel where it is contacted by the second vapor introduced thereto.Type: GrantFiled: October 7, 1980Date of Patent: August 31, 1982Assignee: Bio-Systems Research, Inc.Inventors: Joseph E.
