Title (EN) PROCESS FOR REMOVING ALDEHYDES FROM ETHANOL REACTION MIXTURE
(FR) PROCÉDÉ D'ÉLIMINATION DES ALDÉHYDES D'UN MÉLANGE RÉACTIONNEL D'ÉTHANOL
Abstract:
(EN) A process for purifying an ethanol stream that comprises byproduct, such as aldehyde, acetals, and/or esters, but withdrawing a sidestream comprising ethanol from a distillation column. The sidestream may have a reduced concentration of aldehyde that reduces the formation of acetals in subsequent purification of the ethanol stream.
(FR) L'invention concerne un procédé de purification d'un écoulement continu d'éthanol comprenant un sous-produit, tel que l'aldéhyde, des acétals et/ou des esters, cette purification étant accompagnée du retrait d'un écoulement secondaire comprenant de l'éthanol depuis une colonne de distillation. L'écoulement secondaire peut présenter une concentration réduite d'aldéhydes, réduisant ainsi la formation d'acétals dans un processus ultérieur de purification de l'écoulement continu d'éthanol.
