Abstract
PURPOSE: To desulfurize exhaust gas at high efficiency under the control of scale formation by absorption of SOx with an absorption solution containing sulfamic acid (calcium) and Ca(OH)2 or CaCO3 with specific pH value, and by subjecting directly the absorption solution having absorbed SOx to air-oxidation without control of pH.
