  • Method for removing nitrogen oxides from gases
    Patent number: 4985217
    Abstract: Method for removing nitrogen oxides from gases in which, at first, the molar ratio between NO and NO.sub.2 is set to 1 in said gas and subsequently the nitrogen oxides are absorbed in a hydrous ammonia solution, whereby ammonium nitrate is formed. In order to achieve the desired molar ratio in a simple manner, it is intended for setting the molar ratio between NO and NO.sub.2, to inject NO.sub.2 into the gas in a controlled manner, said NO.sub.2 having been formed by the reaction between ammonium nitrate with a strong acid.
