<p>An apparatus and method for removing sulfur dioxide from a flue gas is described. The apparatus has sequentially operable scrubbing zone and regeneration zone, which communicate with one another via a molten eutectic mixture of lithium, sodium and potassium carbonates. In the scrubbing zone, an ingress flue gas interacts with the molten carbonates, resulting in chemical absorbance of the sulfur dioxide and in discharge of reaction gases. In the regeneration zone, ether a chemical or electrochemical melt regeneration takes place resulting in formation of sulfur-containing vapor which is cooled down for converting the sulfur-containing vapor into a liquid and solid phase for a further collection and utilization.</p> |
