This process uses ozone to oxidize NOx in flue gas into N2O5 which is then effectively removed by an alkali washing system. It is very suitable for wet flue gas desulfurization system due to its high adaptability, minor modifi cation and low investment cost. At present, more than 20 systems have been successfully put into use in China.
This process uses NH℃ as a reductant to convert NOx in flue gas into N2 and H2O in a high temperature environment. It is suitable for the system that has a flue gas temperature window above 800 and a low DeNOx efficiency.
This process uses NH℃ as a reductant to convert NOx into N2 and H2O under the action of catalyst.
