ABSTRACT:
The present invention relates to a process for removing nitrogen oxides from gas streams such as furnace or utility boiler flue gas streams. An ozone adsorption system is used to adsorb and concentrate ozone. A slip stream containing nitrogen oxides is introduced into an ozone adsorption system to desorb ozone and the ozone-containing slip stream gas is then directed to a reactor duct along with the primary nitrogen oxide-containing gas stream where the nitrogen oxides are converted to N.sub.2 O.sub.5.
