Abstract

Un método para lavado de gases que contienen azufre con una solución amoniacal de lavado circulante, en el cual un gas que contiene azufre y que contiene nitrógeno se libera de compuestos de azufre y compuestos de nitrógeno con un disolvente acuoso alcalino de tal manera que se obtiene un gas industrial purificado y un disolvente cargado con compuestos de nitrógeno y compuestos de azufre, que se hace pasar luego a una columna de desorción y se obtiene con ello un gas ácido desorbido que se hace pasar a un proceso Claus de tal manera que la mayor parte de los compuestos de azufre se eliminan, y el gas residual procedente del proceso Claus se hidrogena de tal manera que se obtiene un gas residual que contiene azufre y que contiene amoníaco, que se hace pasar nuevamente a la columna de absorción en la cual se purifica el mismo utilizando el mismo disolvente acuoso que en el primer circuito, después de lo cual el disolvente cargado se hace pasar desde esta columna a la columna de desorción del primer lavador de gases de tal manera que se requiere una sola columna de desorción. De este modo puede utilizarse un solo disolvente, dado que se requiere solamente una columna de desorción, y pueden lograrse ahorros en el requerimiento de espacio del sistema y gasto en aparatos. Reivindicación 12: Un sistema para la realización de un método para lavado (2) de gases que contienen azufre (1) con un disolvente acuoso alcalino circulante (4, 14, 15, 17) según una cualquiera de las reivindicaciones 1 a 11, caracterizado porque dicho sistema contiene una columna de desorción compartida (5) para el disolvente (4) del proceso de lavado de gases (2) para el gas industrial (1) y para el disolvente (14) procedente de la columna de absorción (13) para el gas Claus residual hidrogenado (12b).
