A method of removing SO2 from a flue gas stream including SO2 includes providing a source of trona and injecting the trona into the flue gas stream. The temperature of the flue gas is between about 600° F. and about 900° F. The trona is maintained in contact with the flue gas for a time sufficient to react a portion of the trona with a portion of the SO2 to reduce the concentration of the SO2 in the flue gas stream. |
