Summary: | A dry, regenerable solid oxide process directed to convert SOx from the flue gas stream from a power plant, a coal or oil-fired plant or process heat furnace, or an FCC regenerator to elemental sulfur without using a Claus unit, a hydrogen plant, a regeneration gas separation system, or a hydrogenation section. This dry, regenerable solid oxide process is also effective on Claus plant tail-gas. This process uses solid oxides, such as, for example, magnesium aluminates or spinels to remove sulfur oxides from flue gas streams. The solid oxide is then regenerated by a reducing gas to release the sulfur compounds contained on the solid oxide to produce a gas stream comprising hydrogen sulfide, sulfur oxides and elemental sulfur. The elemental sulfur is then condensed and recovered as a product and the resulting gas stream may be recycled to be reprocessed over the solid oxide. |
