Abstract
Un procedimiento con un instalación de realización para la separación de SO2 de una corriente de gas húmedo que lo contiene, esencialmente en una concentración que, por lo menos intermitentemente, es impermisiblemente elevada para descargase en la atmósfera ambiente con producción simultanea de ácido sulfúrico, mediante el procedimiento de óxido de nitrógeno, en un sistema de zonas de reacción, cuyo sistema es apto para la producción de un ácido sulfúrico fuerte con un contenido de H2SO4 superior al 70% en peso, en cuyo sistema la corriente de gas conteniendo SO2 con un contenido de oxígeno suficiente se hace fluir a una presión manométrica suficiente para conducir el gas a través del sistema sucesivamente (a) a través de una zona de pretratamiento; (b) a través de una zona de desnitración; (c) a través de una zona de elaboración de SO2 en donde se pone en intimo contacto con ácido sulfúrico diluido con una concentración inferior al 70% de H2SO4 (densidad de 1,6515) fluyendo en un ciclo através de la última zona.
