Abstract: Sulfur dioxide and particulate contaminants are removed from industrial waste gases by a method which provides for a highly active sulfur dioxide reactant to be utilized and regenerated. The method further includes discharging stable, insoluble sulfur containing compounds thus eliminating possible reintroduction of sulfur into the environment and regeneration of the sulfur dioxide reactant by using carbon dioxide contained in the stack gas stream.
