Abstract
L'invention concerne un procédé catalytique de fabrication d'acide sulfurique. On fait brûler S dans O2 dans un réacteur pour former un mélange gazeux riche en SO2 et contenant un peu de O2 . On fait passer ce mélange dans un convertisseur catalytique, qui transforme la plupart du SO2 en SO3 . L'acide sulfurique est produit par absorption de SO3 dans un absorbeur. Le convertisseur catalytique comporte au moins 3 étages. Immédiatement en amont d'au moins deux des étages de catalyse, on ajoute au mélange gazeux un mélange contenant au moins 40 % en volume de O2 . L'absorbeur et le convertisseur catalytique fonctionnent tous deux à pression élevée, 10-30 bars. Le procédé permet de recycler la quasi-totalité du gaz non absorbé. L'acide sulfurique produit est une matière de base de l'industrie chimique.
