Patent ID: 7998451

Claim:
A process for removing hydrogen sulfide from liquid sulfur comprising: passing a liquid sulfur feed comprising liquid sulfur and hydrogen sulfide to a vaporizer; vaporizing at least a portion of said liquid sulfur feed in said vaporizer to form a first vapor stream comprising gaseous sulfur and gaseous hydrogen sulfide; partially condensing said first vapor stream in a condenser to form a liquid product stream comprising liquid sulfur and a second vapor stream comprising hydrogen sulfide, wherein said liquid product stream has a lower concentration of hydrogen sulfide than said liquid sulfur feed, wherein an eductor is connected in fluid flow communication with said vaporizer and with said condenser, wherein steam is passed through said eductor, wherein said first vapor stream is educted from said vaporizer into said steam passing through said eductor, thereby resulting in a pressure below atmospheric in said vaporizer and a lower hydrogen sulfide partial pressure, wherein said first vapor stream and said steam are passed to said condenser.
