| titleOfInvention | Method for desulfurization and denitrification of fume and coproduction of ammonium sulfate |
| abstract | The invention discloses a method for desulfurization and denitrification of fume and coproduction of ammonium sulfate. The method comprises the steps that slurry is prepared by a solution containing hydroxy carboxylic acid ligands and pyrite powder, the slurry is used for washing the fume containing sulfur dioxide and nitric oxide, sulfur dioxide and oxygen in the fume react with pyrite, sulfur dioxide and pyritic sulfur are oxidized into sulfate radicals, ferrous generated by leaching the pyrite is combined with aminocarboxylic acid ligands to generate a ferrous complexing agent, the ferrous complexing agent complexes and absorbs nitric oxide in the fume, a complexation product nitrosyl complex continues to react by the action of the pyritic to generate ammonium radicals, and the ammonium radicals are combined with the sulfate radicals to generate ammonium sulfate. According to the method, with the adoption of the pyrite, oxidation degradation of the ferrous complexing agent is inhibited, and the nitrosyl complex continues to react to generate the ammonium radicals. In addition, ferrous ions and the like leached from the pyrite have a catalyst effect in oxidizing sulfur dioxide. |
