Abstract

La presente se refiere a procesos para la separación de etanol de un producto de etanol crudo obtenido de la hidrogenación de ácido acético. El producto de etanol crudo se separa en una o más columnas. Se utiliza un rehervidor luego de una o más de las columnas para reducir la formación de ésteres.Reivindicación 1: Un proceso para producir etanol, que comprende: hidrogenar ácido acético y/o un éster del mismo en un reactor en presencia de un catalizador para formar un producto de etanol crudo; separar al menos una porción del producto de etanol crudo en una primera columna de destilación para proporcionar un primer destilado que comprende acetaldehído y acetato de etilo y una parte inferior de la torre que comprende etanol, ácido acético, y agua; alimentar la parte inferior de la torre a un rehervidor para generar una corriente de vapor de rehervidor, y un producto de residuo, en donde el acetato de etilo se forma en el rehervidor y el producto residual comprende menos de 1,5% en peso de acetato de etilo, preferentemente menos de 1,1% en peso de acetato de etilo; separar al menos una porción del producto residual en una segunda columna de destilación para proporcionar un segundo residuo que comprende componentes de alto punto de ebullición y un segundo destilado que comprende etanol, y acetato de etilo; y separar al menos una porción del segundo destilado para proporcionar un tercer destilado que comprende acetato de etilo y un tercer residuo que comprende etanol.This refers to processes for the separation of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid. The crude ethanol product is separated into one or more columns. A reboiler is used after one or more of the columns to reduce the formation of esters. 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 for form a crude ethanol product; separating at least a portion of the crude ethanol product in a first distillation column to provide a first distillate comprising acetaldehyde and ethyl acetate and a lower part of the tower comprising ethanol, acetic acid, and water; feeding the lower part of the tower to a reboiler to generate a reboiler steam stream, and a waste product, wherein ethyl acetate is formed in the reboiler and the residual product comprises less than 1.5% by weight of ethyl acetate, preferably less than 1.1% by weight ethyl acetate; separating at least a portion of the residual product in a second distillation column to provide a second residue comprising high boiling components and a second distillate comprising ethanol, and ethyl acetate; and separating at least a portion of the second distillate to provide a third distillate comprising ethyl acetate and a third residue comprising ethanol.
