Abstract |
The chemical contacting potential of fabric filters was evaluated with emphasis on the 600-1000 F temperature range according to a new fabric capability. SO2 was carried in flue gases that closely resembled in composition the effluent of coal-burning facilities. The technical feasibility of using a glass fabric filter bag house as a collector of reacted materials and as a contactor for reactants to remove objectional gases from exhaust gas streams up to temperatures of 900 F was demonstrated. Of the reactant materials investigated in the temperature range of 700 F to 900 F, slaked lime and slaked dolomite are possible candidates for SO2 removal in the filter bag system from a standpoint of reactant efficiency, total SO2 removal and potential economical cost. In the temperature range of 300 F to 500 F, alkalyzed alumina proved to be very effective for SO2 removal, but would probably require regeneration for its economical use. Nahcolite, a naturally occurring sodium bicarbonate, is also effective in removing SO2 in the temperature range of 300 F to 500 F but would also require regeneration to be economical. Manganese dioxide can be used most effectively in the temperature range of 500 F to 700 F, but also requires regeneration to be economically useful. (NAPCA-abstract) |
