Abstract

Selon l'invention, on brûle les résidus organiques liquides dans une chambre de combustion avec de l'oxygène en excès par rapport à la quantité nécessaire pour une oxydation totale de la matière combustible et on envoie les produits de combustion gazeux avec un gaz réducteur successivement dans des refroidisseurs, des condenseurs et des lits catalytiques, en récupérant le soufre élémentaire aux condenseurs. Le soufre élémentaire récupéré selon l'invention a des applications industrielles multiples.According to the invention, the liquid organic residues are burned in a combustion chamber with oxygen in excess with respect to the amount necessary for total oxidation of the combustible material and the gaseous combustion products are sent successively with a reducing gas. in coolers, condensers and catalytic beds, recovering elemental sulfur at condensers. The elemental sulfur recovered according to the invention has multiple industrial applications.
