Dry injection of trona or sodium bicarbonate is a cost effective way to mitigate HCl, SO2 and SO3, and is compatible with ESP and Baghouses.  DSI is able to achieve high removal rates for HCl (>99%) and SO2 (90%).  It is effective over a wide temperature range (275-1500oF) and has been implemented at many coal fired power plants in the United States.
