Abstract

LA PRESENTE INVENTION CONCERNE UN PROCEDE DE FABRICATION DE L'ANHYDRIDE SULFUREUX, UTILISE DANS LA PRODUCTION DE L'ACIDE SULFURIQUE ET DANS L'INDUSTRIE DES PATES A PAPIER. LE PROCEDE DE FABRICATION DE L'ANHYDRIDE SULFUREUX CONSISTE EN CE QUE LE SOUFRE EST FONDU ET VAPORISE PAR BARBOTAGE D'OXYGENE A TRAVERS UN BAIN DE SOUFRE FONDU ET QUE LES VAPEURS DU SOUFRE AINSI FORMEES SONT OXYDEES PAR L'OXYGENE DANS UN LIT FLUIDISE EN MATERIAU INERTE. LE PRODUIT VISE OBTENU A UNE CONCENTRATION EN ANHYDRIDE SULFUREUX POUVANT ATTEINDRE 100 EN VOLUME. LE PROCEDE SELON L'INVENTION PERMET DE TRAVAILLER AVEC UN RENDEMENT POUVANT ATTEINDRE 2000 A 3500KG PAR M DE LA SURFACE DE LA COUCHE ET PAR HEURE SOUS DES PRESSIONS DE 1 A 35ATM.
