Abstract

a. Procédé d'introduction d'un produit hydrocarboné contenant de l'oxygène et/ou un précurseur de celui-ci dans des gaz d'échappement de combustion suivant un processus de dénitrification par voie humide, dans lequel on ajoute aux gaz un tel produit hydrocarboné contenant de l'oxygène et/ou le précurseur correspondant en oxydant ainsi l'oxyde d'azote de ces gaz en dioxyde d'azote, puis en éliminant ce dioxyde d'azote par absorption dans une solution absorbante. b. On utilise les gaz d'échappement en tant que gaz porteurs pour le produit hydrocarboné et/ou le précurseur. c. L'invention est applicable notamment aux gaz des chaudièresat. A method of introducing a hydrocarbon product containing oxygen and / or a precursor thereof into combustion exhaust gases following a wet denitrification process, in which such a hydrocarbon product is added to the gases containing oxygen and / or the corresponding precursor, thereby oxidizing the nitrogen oxide of these gases to nitrogen dioxide, then eliminating this nitrogen dioxide by absorption in an absorbent solution. b. The exhaust gases are used as carrier gases for the hydrocarbon product and / or the precursor. vs. The invention is particularly applicable to gas from boilers
