Abstract

La presente invención se refiere a un proceso continuo para eliminar sulfuro de hidrógeno de una corriente fluida, caracterizado porque comprende los pasos de; poner en contacto la corriente que contiene sulfuro de hidrógeno con sulfitos en una solución acuosa, esencialmente libre de quelato y peróxido de metal polivalente, para formar tiosulfato en dicha solución y para obtener una corriente parcialmente tratada, con contenido de sulfuro de hidrógeno reducido, incinerar la corriente parcialmente tratada, para convertir sustancialmente el sulfuro de hidrógeno restante a dióxido de azufre, absorber selectivamente el dióxido de azufre en una solución acuosa, bajo condiciones adecuadas para la formación de sulfitos acuosos y para evitar sustancialmente la formación de carbonatos precipitables; y suministrar los sulfitos acuosos del paso de absorción, al paso de contacto.
