Disclosed is a process for degassing liquid sulfur under pressure. A stream of liquid sulfur containing polysulfides and hydrogen sulfide and a stream of an oxidizing gas are introduced into a vessel and intimately mixed to provide intimate contact between the two streams. The streams are passed through the vessel at a pressure of at least about 40 psig and at a temperature and for a residence time sufficient to remove substantially all of the polysulfides and hydrogen sulfide from the liquid sulfur.

Procédé de dégazage du soufre liquide sous pression. Un flux de soufre liquide contenant des polysulfures et de l'hydrogène sulfuré et un flux d'un gaz oxydant sont introduits dans une cuve et intimement mélangés de sorte qu'il y ait contact intime entre les deux flux. Les flux traversent la cuve sous une pression d'au moins environ 40 psig et à une température et durant un temps de séj our suffisants pour éliminer sensiblement tous les polysulfures et l'hydrogène sulfuré contenus dans le soufre liquide.
