Abstract

La presente invención se refiere a un procedimiento para separar un gas ácido de un gas no ácido con el cual se mezcla; dicho procedimiento se caracteriza en que comprende las etapas que consisten en: a) poner en contacto el gas mixto con un disolvente, a una presión de absorción; b) separar la fase gaseosa que resulta, que tiene su contenido en gas ácido relativamente agotado y el disolvente enriquecido que contiene al gas ácido disuelto; c) reducir la presión del gas, que se ejerce sobre el disolvente enriquecido, a una presión de desabsorción menor que la presión de absorción, por lo cual el gas ácido pasa de la fase disolvente a la fase gaseosa; d) separar el gas ácido desabsorbido del disolvente y e) reciclar el disolvente desabsorbido para extraer más gas ácido de una nueva cantidad de la mezcla gaseosa; el disolvente consta esencialmente de uno o más compuestos que tienen la fórmula química genérica: (CH3)2CHO(C2H4O)x-HC-(CH3)2, en la cual: x es un número entero comprendido entre 2 y 8.
