ABSTRACT:
The present invention is directed to a method of removing sulfur dioxide from flue gases derived from furnaces burning high sulfur content fuels. The method comprises spraying flue gases with an aqueous medium containing (i) a material either dissolved or slurried therein, which material reacts with the sulfur dioxide in the flue gas to produce calcium sulfate and calcium sulfite, and (ii) a sufficient amount of a water-soluble surfactant (surface active agent) or mixtures thereof to improve sulfur dioxide removal.
