Abstract

L'invention concerne un procédé et un appareil pour la désulfuration d'un gaz réducteur chaud par mise en contact dudit gaz avec un agent désulfurant, puis régénération de l'agent désulfurant usé, puis réutilisation de l'agent désulfurant régénéré pour la désulfuration d'une nouvelle quantité de gaz réducteur chaud L'appareil selon l'invention comprend comme agent désulfurant un bain de cuivre fondu 28 et comme dispositif de régénération un réacteur 32 pour la mise en contact de l'agent use avec une atmosphère de gaz oxydantThe invention relates to a method and apparatus for the desulfurization of a hot reducing gas by contacting said gas with a desulfurizing agent, then regenerating the spent desulfurizing agent, and then reusing the regenerated desulfurizing agent for the desulfurization of the gas. 'a new quantity of hot reducing gas The apparatus according to the invention comprises as desulfurizing agent a bath of molten copper 28 and as regeneration device a reactor 32 for bringing the used agent into contact with an atmosphere of oxidizing gas
