Abstract

Lors du mélange de deux gaz de différentes températures et/ou compositions dans un convertisseur pour produire du SO3 à partir d'un gaz contenant du SO2, un premier écoulement de gaz est introduit à l'intérieur d'une chambre de mélange par le dessous, tandis qu'un second écoulement de gaz est introduit à contre-courant à l'intérieur de la chambre de mélange par le dessus. Le mélange gazeux obtenu dans la chambre de mélange est déchargé de la chambre de mélange par l'intermédiaire d'un tube de liaison dirigé vers le haut et adressé à un échangeur de chaleur intégré dans le convertisseur.
