3.Denitrification reaction principle. The principle of denitrification by SCR technology is as follows: under the action of catalyst, ammonia is put into flue gas at a temperature of 280 ℃~420 ℃, and NOX is reduced to N2 and H2O. The main reactions are as follows: 4NO+4NH3+O2→4N2+6H2O. 6NO+4NH3→5N2+6H2O.

Flue-gas desulfurization - Wikipedia

SO 2 is an acid gas, and, therefore, the typical sorbent slurries or other materials used to remove the SO 2 from the flue gases are alkaline. The reaction taking place in wet scrubbing using a CaCO 3 slurry produces calcium sulfite (CaSO 3) and may be expressed in the simplified dry form as: . CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g). When wet scrubbing with a Ca(OH) 2 (hydrated lime
