FIELD: chemistry.
SUBSTANCE: invention refers to a method and a device for conditioning an amine solvent contaminated with introduced sulphur dioxides. The contaminated solvent is added with a potassium compound and an oxidising agent thereby oxidising sulphite to sulphate; the oxidising agent and potassium compound are mixed before adding an amino acid salt to the solution. The contaminated solvent is cooled down to a temperature T, thereby reducing the potassium sulphate solubility as compared to its actual concentration. Potassium sulphate is filtered to produce the conditioned solvent.
EFFECT: invention enables providing removing sulphate from the solution.
