The implement process of de-nitration is as follows : firstly the NO was oxidized into NO2 by means of catalyze-oxidize-absorb on the setups of circulating fluid bed flue gas desulfurization, secondly the NO2 reacts with atomized water and forms HNO3 , thirdly the formed HNO3 goes on neutralization reaction with Ca-based absorbent . This process is simple in structure and invest little . Data from pilot scale production shows the denitration effect can reach up to 70% . However there is much needs for improvement and optimization .
