PREPARATION OF AN AMINE-BASED SOLVENT CONTAMINATED BY INTRODUCTION OF SULFUR OXIDES

摘要

The invention relates to a method and device for preparing an amine based solvent (1) contaminated by the introduction of sulfur oxides. By cooling the contaminated solvent (1) and adding a potassium compound, potassium sulfate is precipitated, in that the concentration of potassium sulfate is brought to a value above the potassium sulfate solubility limit. The potassium sulfate is filtered out, wherein a prepared solvent (3) is formed.
