Abstract
A method for removing NOfrom flue gas by SCR includes supplying a reagent for the SCR reaction of NOinto the flue gas, then contacting the flue gas with a catalyst. Supplying the reagent includes supplying a less than stoichiometric amount of reagent, and after contacting the flue gas with a catalyst a final NOremoval step is provided.
