| titleOfInvention | Method for removing sulfur dioxide in tail gas from industrial kiln and method for comprehensively utilizing tail gas from industrial kiln |
| abstract | The invention relates to a method for removing sulfur dioxide in tail gas from an industrial kiln, which comprises the following step: enabling a hexavalent-chromium-containing sodium hydrogen sulfate solution used as an oxidizing absorption solution to be in contact with the tail gas from the industrial kiln, thus removing sulfur dioxide in the tail gas from the industrial kiln, wherein the hexavalent-chromium-containing sodium hydrogen sulfate solution is a byproduct in the chrome acid anhydride production process based on a sulfuric acid method. The invention also relates to a method for comprehensively utilizing the hexavalent-chromium-containing sodium hydrogen sulfate solution byproduct in the chrome acid anhydride production process based on a sulfuric acid method and the tail gas from the industrial kiln, which comprises the following step: enabling the hexavalent-chromium-containing sodium hydrogen sulfate solution used as an oxidizing absorption solution to be in contact with the tail gas from the industrial kiln, thus removing sulfur dioxide in the tail gas from the industrial kiln, and obtaining carbon dioxide gas and an oxidizing absorption finished solution containing chromium sulfate, sodium hydrogen sulfate and sulfuric acid, wherein the hexavalent-chromium-containing sodium hydrogen sulfate solution is a byproduct in the chrome acid anhydride production process based on a sulfuric acid method. According to the method for removing sulfur dioxide, the operating cost is low, and the sulfur dioxide removal rate is high. According to the comprehensive utilization method, the comprehensive utilization rate is high. |
