Abstract
PURPOSE: To increase desulfurization ratio and reaction ratio of lime and to produce gypsum by oxidation in a absorption column by use of a slurry of steel making slag as desulfurizing agent and by specifying SO2/O2 (concentration ratio) of exhaust gas at the inlet of the absorption column and pH of the slurry.
