Method for removing hydrogen sulfide from gas streams

Patent ·
OSTI ID:6306451

A hydrogen sulfide removal and conversion method in which a hydrogen sulfide-containing gas stream is contacted with a regenerable washing solution capable of absorbing the hydrogen sulfide and converting the hydrogen sulfide to hydrophobic elemental sulfur particles. After oxidative regeneration of the washing solution, the sulfur particles are transferred to a nonaqueous carrier liquid to thereby form a substantially nonaqueous sulfur slurry which is then heated to melt the sulfur and form a dense liquid sulfur product which separates by gravity from the carrier liquid.
