ABSTRACT:
For the separation of sulfur from a sulfur/alkaline solution suspension, the suspension is heated to a temperature above the melting temperature of the sulfur and is introduced under pressure into a separating tank 1, containing a separating chamber 8, alkaline solution chamber, and sulfur chamber 12. From the separating tank, settled liquid sulfur is continuously withdrawn, on the one hand, via conduit 16 and alkaline solution is continuously withdrawn, on the other hand, via conduit 9. In order to provide a system having little susceptibility to trouble, the separating chamber and alkaline solution chamber are operated in the flooded mode, thereby avoiding the necessity for a steam blanket therein.
