  • Patent number: 5026528
    Abstract: A method and system for removing hydrogen sulfide from a hot gas. In a moving bed absorber, sulfur compounds in the hot gas moving in a direction which is countercurrent to the direction of movement of the movable bed of metal oxide, react with metal oxide to form metal sulfide. The metal sulfide is regenerated to re-usable metal oxide in a moving bed regenerator. The regeneration is carried out with an oxygen-containing gas in which regenerator off-gas serves as a diluent to control oxygen concentration. In the regenerator, spent metal sulfide moves progressively through a single regeneration vessel having first, second and third regeneration stages. In the first and second regeneration stages, first and second oxygen and sulfur dioxide-containing gases move, respectively, in a direction which is cocurrent with the direction of movement of a movable bed of spent metal sulfide.
