Abstract

Procédé de récupération de soufre comprenant, dans un réacteur d'hydrogénation, la conversion de composés contenant du soufre dans un flux de gaz résiduaire de Claus en sulfure d'hydrogène pour produire un flux de gaz hydrogéné ; l'introduction du flux de gaz hydrogéné dans une tour de trempe pour produire un flux de gaz trempé par condensation d'eau liquide ; l'introduction du flux de gaz trempé dans un récipient d'adsorption de premier étage d'une unité d'adsorption de premier étage pour produire un premier flux de gaz de sortie par adsorption d'eau à partir du flux de gaz trempé ; l'introduction du premier flux de gaz de sortie dans un récipient d'adsorption de second étage d'une unité d'adsorption de second étage pour produire un second flux de gaz de produit par adsorption de sulfure d'hydrogène à partir du premier flux de gaz de sortie ; la séparation du second flux de gaz de produit en un flux de dioxyde de carbone et un flux d'azote enrichi ; et la régénération du récipient d'adsorption de second étage à l'aide du flux d'azote enrichi.
