Flue Gas Denitrification

The characteristics of ozone application in the oxidation and denitrification industry: Ozone has a high selectivity to NOx and a fast speed, and O3 can basically complete the oxidation of NO at 0.05s. The absorption of oxidized products should be strengthened by the spray absorption process at the back end. Without heating the flue gas, N2O5 is easily absorbed by the lye, and some heavy metals such as mercury and other heavy metal pollutants are also oxidized and removed by ozone. A high concentration of dust or solid particles in flue gas will not affect NOx removal efficiency. A high concentration of dust or solid particles in flue gas will not affect NOx removal efficiency. According to the NOx concentration of flue gas, can flexible adjustment of ozone production. 

According to the complex oxidation reaction process of O3 for NOx, in fact, it is finally reflected through the change of valence state of N. The main reactions are as follows:

NO+O3=NO2+O2

2NO2+O3=N2O5+O2

2NO+3O3=N2O5+3O2
