Abstract

Purificación y/o recuperación del etanol a partir de un producto bruto obtenido de etanol a partir de la hidrogenación del ácido acético. Los procesos de separación y purificación de una mezcla de etanol en bruto se emplean para permitir la recuperación del etanol y eliminar las impurezas. En particular, el proceso implica uno o más corrientes secundarias para regular la concentración de alcoholes C3+ en el etanol recuperado.Reivindicación 1: Un procedimiento para producir etanol, que comprende: hidrogenación de ácido acético en un reactor en presencia de un catalizador para formar un producto de etanol en bruto; separar, al menos una porción del producto de etanol en bruto en una primera columna de destilación para producir un primer residuo que contiene ácido acético y agua, en el que una porción sustancial del agua en el producto de etanol en bruto que se alimenta a la columna, se retira en el primer residuo, un primer destilado que contiene etanol, acetato de etilo y agua, y uno o más corrientes secundarias que contienen uno o más alcoholes C3+; eliminar el agua de, al menos una porción del primer destilado para producir una primera corriente de mezcla de etanol que contiene menos del 10 por ciento por peso de agua; y recuperar el etanol a partir de la corriente de mezcla de etanol. Reivindicación 11: Un procedimiento para producir etanol, que comprende: la hidrogenación del ácido acético en un reactor en presencia de un catalizador para formar un producto de etanol en bruto; separar una porción del producto de etanol en bruto en una primera columna de destilación para producir un primer destilado que contiene acetato de etilo y un primer residuo que contiene uno o más alcoholes C2+, ácido acético y agua, en el que la mayoría del etanol en el producto de etanol en bruto que alimenta la columna se retira en el primer residuo; separar una porción del primer residuo en una segunda columna de destilación para producir un segundo residuo que contiene ácido acético y agua, un segundo destilado que contiene etanol, y una o más corrientes secundarias que contienen uno o más alcoholes C3+.
