Patent abstract
A process is disclosed for removing hydrogen sulfide from liquid sulfur including: passing a liquid sulfur feed comprising liquid sulfur and hydrogen sulfide to a vaporizer; vaporizing at least a portion of the liquid sulfur feed in the vaporizer to thereby form a first vapor stream comprising gaseous sulfur and gaseous hydrogen sulfide; partially condensing the first vapor stream in a condenser to form a liquid product stream comprising liquid sulfur and a second vapor stream comprising hydrogen sulfide; wherein the liquid product stream has a lower concentration of hydrogen sulfide than the liquid sulfur feed.
