Selective catalytic reduction (SCR) is a means of converting nitrogen oxides, also referred to as NO x with the aid of a catalyst into diatomic nitrogen (N 2), and water (H 2O). A reductant, typically anhydrous ammonia (NH 3), aqueous ammonia (NH 4OH), or a urea (CO(NH 2) 2) solution, is added to a stream of flue or exhaust gas and is reacted onto a catalyst. As the reaction drives toward completion, nitrogen (N 2), and carbon dioxide (CO 2), in the case of urea use, are produced. WebbSCR is the most widely used technology to reduce NO x emissions following combustion in coal-fired plant. These systems have been found to influence Hg emissions.
