Abstract: The invention concerns a method of removing nitrogen oxides from a gas flow. The gas flow is guided: (A) through a stage in which the nitrogen oxides, apart from N2O, are absorbed in an absorption agent, or the nitrogen oxides, apart from N2O, are reacted with an absorption agent at a pressure of between 1.5 and 20 bar; and (B) through a stage for reducing the N2O content, preferably using the pressure level prevailing in step (A). The invention further concerns a device for carrying out this method and the use thereof.
