Abstract
Se describe un procedimiento y un dispositivo de tratamiento de un gas que contiene sulfuro de hidrogeno y anhídrido sulfuroso, en el cual se ponen en contacto en al menos un reactor-contactor gas-líquido (2) a una temperatura adecuada, un gas con un solvente orgánico (1), conteniendo un catalizador, y se recupera un gas (20) que no contiene sensiblemente más sulfuro de hidrogeno y anhídrido sulfuroso. Más particularmente, se extrae el reactor-contactor, una solucion monofásica (4) de solvente y de azufre, se enfría una parte en al menos una zona de enfriamiento (8), de manera de obtener una suspension de cristales de azufre en el solvente, se separa el azufre cristalizado del solvente en una zona de separacion (10) y se recupera una parte del solvente pobre (14, 15) en azufre que se recircula (1) al menos en parte en el reactor-contactor (2), y de otra parte de azufre (13). Aplicacion en la purificacion de efluentes de unidades Claus.
