Abstract

Procesos para recuperar etanol obtenido a partir de la hidrogenación de ácido acético. El ácido acético es hidrogenado en la presencia de un catalizador en un reactor de hidrogenación para formar un producto de etanol crudo. El producto de etanol crudo es separado en una o más columnas para recuperar etanol. En algunas realizaciones, menos del 10% en peso de etanol se recicla hasta el reactor de hidrogenación.Reivindicación 1: Un proceso para producir etanol que comprende: hidrogenar ácido acético y/o un éster del mismo en un reactor en la presencia de un catalizador para formar una corriente de etanol crudo; separar una porción de la corriente de etanol crudo en una primera columna de destilación para producir un primer destilado que comprende acetaldehído, acetato de etilo y etanol, y un primer residuo que comprende etanol, ácido acético y acetato de etilo; separar una porción del primer residuo en una segunda columna de destilación para producir un segundo residuo que comprende ácido acético y un segundo destilado que comprende etanol y acetato de etilo; y separar por lo menos una porción del segundo destilado en una tercera columna de destilación para producir un tercer destilado que comprende acetato de etilo y un tercer residuo que comprende etanol, en donde el primer destilado se hace retornar al reactor y menos de 10% del etanol desde la corriente de etanol crudo se hace retornar al reactor.Processes to recover ethanol obtained from the hydrogenation of acetic acid. Acetic acid is hydrogenated in the presence of a catalyst in a hydrogenation reactor to form a crude ethanol product. The crude ethanol product is separated into one or more columns to recover ethanol. In some embodiments, less than 10% by weight of ethanol is recycled to the hydrogenation reactor. Claim 1: A process for producing ethanol comprising: hydrogenating acetic acid and / or an ester thereof in a reactor in the presence of a catalyst to form a stream of crude ethanol; separating a portion of the crude ethanol stream in a first distillation column to produce a first distillate comprising acetaldehyde, ethyl acetate and ethanol, and a first residue comprising ethanol, acetic acid and ethyl acetate; separating a portion of the first residue in a second distillation column to produce a second residue comprising acetic acid and a second distillate comprising ethanol and ethyl acetate; and separating at least a portion of the second distillate into a third distillation column to produce a third distillate comprising ethyl acetate and a third residue comprising ethanol, wherein the first distillate is returned to the reactor and less than 10% of the Ethanol from the raw ethanol stream is returned to the reactor.
