ABSTRACT:
Degasification of liquid sulfur produced by the Claus process to remove hydrogen sulfide. The liquid sulfur is caused to flow continuously through a vessel where it is contacted by a counter-flowing inert gas, thereby stripping hydrogen sulfide from the sulfur. Nitrogen and air are preferred examples of inert gas which can be used in the method.
