Abstract
La presente invención se refiere a procedimiento para la separación de compuestos de azufre y de sodio, a partir de un gas de proceso generado durante la gasificación de una solución de desecho en la industria de la fabricación de papel, a través de ponerlo en contacto con líquidos alcalinos que contienen ion de sulfuro de hidrógeno y un ión de hidróxido, en dos o más etapas, caracterizado porque el gas de proceso en una primera etapa pasa a través de una garganta venturi y/o una trampa de líquidos, en donde se ponen en contacto con un líquido de lavado alcalino, con lo cual las gotas en fusión en el gas de proceso se separan del gas y se extraen como una solución acuosa, con lo cual el gas de proceso en una etapa de lavado subsecuente se pone en contacto con un líquido de lavado finamente disperso que contiene iones de hidróxido y iones de sulfuro de hidrógeno con una relación mayor que 4 : 1.
