Abstract
Procédé et appareillage pour l'oxydation catalytique en plusieurs stades opératoires des composés gazeux du soufre en SO3 . Dans tous les stades opératoires, les gaz de réaction sont maintenus à une température dans l'intervalle de 400 à 580 degrés C à l'aide d'un agent de transfert de la chaleur liquide qui est en échange de chaleur d'une part avec tous les étages de catalyse le long du trajet des gaz de réaction et d'autre part avec au moins un appareil consommateur de chaleur ou, le cas échéant, au moins un appareil producteur de chaleur, l'agent de transfert de la chaleur circulant entre les étages de catalyse et l'appareil consommateur ou producteur de chaleur avec des variations de température qui sont au maximum d'environ 5 degrés C. Le procédé selon l'invention permet de supprimer tous les incidents dus à des arrêts de fonctionnement ou à des variations dans la composition et le débit des gaz à convertir.
