Abstract: A method for treating flue gas including sulphur oxides and nitrogen oxides includes: cooling the furnace outlet flue gas; contacting it with a sulphur oxide neutralization agent, reducing the sulphur oxides by desulphurization reactions, and obtaining residues; separating the residues from the flue gas; reheating the flue gas; injecting a nitrogen oxide neutralization agent therein; and placing the reheated flue gas and the nitrogen oxide neutralization agent in contact with a catalyst, reducing the nitrogen oxides by denitrification reactions, the cooling of the flue gas achieved by reheating, inside the same heat exchanger, the flue gas separated from the desulphurization residues. The reheated flue gas is mixed, after injecting the nitrogen oxide neutralization agent, with the flue gas cooled after being placed in contact with the sulphur oxide neutralization agent, the separation of the residues and the contact with the catalyst being carried out inside a single separation device.
