Abstract

Un procedimiento para recuperar etanol obtenido de la hidrogenación de ácido acético; el producto de etanol crudo es separado en una columna para producir una corriente de destilado que comprende acetaldehído y acetato de etilo, y una corriente de residuo que comprende etanol, ácido acético, acetato de etilo y agua; se elimina el agua de por lo menos una porción del vapor de descarga para producir una corriente de mezcla de etanol que tiene un contenido menor de agua que la por lo menos una porción del vapor de descarga.
