A method for processing an amine-based solvent contaminated by the introduction of sulfur oxides is provided. A potassium compound is introduced into a contaminated solvent, and the contaminated solvent is cooled so that a solubility of a potassium sulfate becomes less than a specified concentration of potassium sulfate. Further, an oxidizing agent is introduced into the contaminated solvent so that a potassium sulfite is oxidized to potassium sulfate. The potassium sulfate is filtered out, wherein a prepared solvent is formed. Further, a device for processing an amine-based, sulfur oxide-contaminated solvent is provided. |
