ABSTRACT:
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.
