Abstract
A process and system for removal of hydrogen sulfide from a hydrogen sulfide-containing gaseous stream comprising contacting the hydrogen sulfide-containing gaseous stream with a nonaqueous phase sorbent under conditions suitable for forming a hydrogen sulfide-laden sorbent and a clean gaseous stream. The hydrogen sulfide-laden sorbent is mixed with an aqueous phase redox coupled, regenerating the nonaqueous phase sorbent, reducing the aqueous phase redox couple, and forming sulfur. The sulfur is separated from the mixture. The reduced aqueous phase redox couple is extracted from the mixture and regenerated with an oxidizing agent or electrochemical cell.
