Title
(EN) METHOD FOR THE PRODUCTION OF CONCENTRATED ALCOHOL FROM FERMENTATION BROTHS
(FR) PROCÉDÉ POUR LA PRODUCTION D’ALCOOL CONCENTRÉ À PARTIR DE BOUILLONS DE FERMENTATION
Abstract
(EN) A method for obtaining a concentrated alcohol solution from a lignocellulosic feedstock. The lignocellulosic feedstock is hydrolyzed to prepare a sugar solution. The sugar solution is fermented to produce a fermentation broth comprising alcohol and at least about 1 g ammonium ions/kg fermentation broth. The alcohol in the fermentation broth is then concentrated by distillation to produce an alcohol-enriched vapour. Either before distillation, during distillation or during the azeotrope breaking process, the concentration of ammonia in the alcohol-enriched vapour can be reduced by acid addition to at most about 300 ppm. The alcohol in the alcohol-rich vapour is then further concentrated by an azeotrope breaking process to provide the concentrated alcohol solution.
(FR) L’invention concerne un procédé pour l’obtention d’une solution concentrée d’alcool à partir d’une charge d'alimentation lignocellulosique. La charge d'alimentation lignocellulosique est hydrolysée pour préparer une solution de sucres. La solution de sucres est amenée à fermenter pour produire un bouillon de fermentation comprenant de l’alcool et au moins environ 1 g d’ions ammonium/kg de bouillon de fermentation. L’alcool dans le bouillon de fermentation est ensuite concentré par distillation pour produire une vapeur enrichie en alcool. Soit avant la distillation, soit pendant la distillation, soit pendant le procédé de cassage de l’azéotrope, la concentration de l’ammoniac dans la vapeur enrichie en alcool peut être réduite par ajout d’acide à hauteur d’au maximum environ 300 ppm. L’alcool dans la vapeur riche en alcool est encore concentré par un procédé de cassage d’azéotrope pour fournir la solution concentrée d’alcool.
