Abstract

Un proceso para producir etanol que comprende los pasos de hidrogenar una corriente de alimentación de ácido acético para formar un producto de etanol crudo y separar al menos una porción del producto de etanol crudo para formar una corriente de etanol y al menos una corriente de ventilación. La corriente de ventilación comprende gases no condensables y al menos un elemento orgánico volátil. El proceso además comprende el paso de depurar la corriente de ventilación con al menos dos solventes diferentes para recuperar los elementos orgánicos volátiles. La corriente de ventilación puede incluso comprender etanol arrastrado, que también se puede recuperar.Reivindicación 1: Un proceso para producir etanol, que comprende: (a) hidrogenar una corriente de alimentación de ácido acético para formar un producto de etanol crudo; (b) separar al menos una porción del producto de etanol crudo para formar una corriente de etanol y al menos una corriente de ventilación que comprende gases no condensables y al menos un elemento orgánico volátil; (c) depurar con un primer solvente de depuración al menos una porción de la al menos una corriente de ventilación para formar corrientes de la parte inferior y una corriente intermedia; y (d) depurar con un segundo solvente de depuración diferente del primer solvente de depuración al menos una porción de la corriente intermedia para formar una corriente de ventilación depurada.
