Title: Low-temperature desulfurization method
Inventor: KATO KUNIO
IPC: B01D53/34
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To enhance the desulfurization efficiency at a low reaction temp. SOLUTION: The air from a compressor 1 and the gaseous SO2 from a cylinder 6 are mixed to form gas contg. the SO2 . This gas is heated in a gas heating furnace 8 and is supplied to a desulfurization reactor 10. The medium particles in this desulfurization reactor 10 are fluidized to form a fluidized bed in the desulfurization reactor 10. The soln. or slurry of the desulfurizer from a slurry tank 11 is supplied through respective pumps 12, 13 to the desulfurization reactor 10. The desulfurizer sticks to the surfaces of the medium particles and absorbs the SO2 on the surface of the medium particles, thereby progressing the desulfurization reaction. The moisture in the desulfurizer is evaporated by the heat of the gas simultaneously therewith, by which the reaction product and the unreacted desulfurizer are dried and solidified on the medium particle surfaces.  The reaction product and undried desulfurizer subjected to drying and solidifying are peeled as fine powder from the surfaces of the medium particles by the vigorous motion of the medium particles and are discharged together with the gases from the desulfurization reactor 10 and are captured by cylindrical filter paper 17.
