Simultaneous removal of SO2 and NOx with ammonia combined with gas-phase oxidation of NO using ozone [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2015
A process for simultaneous desulfurization and denitrification was proposed, which was made up of ozone as the oxidizing agent for NO and ammonia solution as absorbent. The results showed that the presence of SO2 and the concentration changes of
