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.
