Advantages of ozone for oxygen desulfurization and denitrification

Flue gas denitrification is the removal of NOX from flue gas by reducing the generated NOX to N2. The principle of flue gas denitrification is to oxidize NO to NO2 by oxidizing agent, and then the NO2 is absorbed by water or alkaline solution, so as to realize denitration. The traditional flue gas desulfurization denitrification process has been unable to meet the strict requirements of the reduction, the traditional process has the disadvantages of high equipment investment, covering a large area, so the development of desulfurization technology is simple, reliable has important significance in denitrification process. Ozone is out of stock only take off NOX in the flue gas, the main component of NOX in flue gas is NO, the advanced oxidation of ozone can achieve the removal effect, and other harmful gases in the flue gas can also be removed. Ozone, as a strong oxidant, can easily oxidize NO to NO2, N2O3, N2O5 and other high valence nitrogen oxides which are soluble in water to form HNO2 and HNO3. Then Na2S and NaOH solution were used to absorb, and finally NOx was converted into N2 to achieve the purpose of removal, the removal rate of NOx was as high as 95%.
