Abstract

La présente invention porte sur un procédé de réduction des niveaux doxydes dazote dans des courants de gaz de procédé provenant dinstallations de régénération dacide sulfurique et de production dacide sulfurique. Le courant de gaz de procédé provenant de la chaudière de récupération et de léliminateur de brouillard à bougies est mis en contact avec de lozone qui réagira avec les oxydes dazote présents dans le gaz de carneau.
