Abstract

The present invention provides, according to one aspect thereof, a method for reducing SO2 from a flue gas (40) and, according to a different aspect thereof, an apparatus (160) for reducing SO2 from a flue gas (40). The method includes the basic steps of providing an alkaline earth material (204) which has been treated by an aqueous treatment solution (202) consisting of an inorganic salt and heating the alkaline earth material (204) in the presence of the flue gas (40) containing SO2 to remove the SO2. The alkaline earth material (204) may be limestone or dolomite. The inorganic salt is selected from the group consisting of thermally decomposable sodium compounds including sodium carbonate, sodium bicarbonate, sodium hydroxide, sodium nitrate, and sodium acetate. In selected application of the method of the present invention, the inorganic sodium compound has a concentration of between 0.05 to 5 percent of the limestone or dolomite. In preferred applications of the method, the inorganic sodium compound has a concentration of between 0.05 to 1 percent of the limestone or dolomite.
