摘要： A method and system for hydrogen sulfide removal from a sour gas mixture including hydrogen sulfide includes providing an aqueous solution comprising a transition metal oxide, sulfide or carbonate compound, wherein a transition metal of the transition metal oxide is at a first valence and has at least one reduction state from the first valence. The sour gas mixture is reacted with the transition metal compound and the aqueous solution in a reactor, wherein sulfide from the hydrogen sulfide is oxidized to form elemental sulfur and the transition metal is reduced to form a reduced state transition metal compound. An electrochemical redox reaction is performed including the reduced state transition metal compound to regenerate the transition metal compound in an electrolyzer comprising an anode, a cathode, and an electrolyte membrane between the anode and cathode, wherein an oxygen including gas is added to the cathode during the electrochemical redox reaction. The transition metal compound that is regenerated in the electrochemical redox reaction is then returned to the reactor for the reacting.

摘要： A system for hydrogen sulfide removal from a sour gas mixture including hydrogen sulfide. The sour gas mixture is reacted with a transition metal compound in a scrubber. Sulfide from the hydrogen sulfide is oxidized to form elemental sulfur and the transition metal is reduced to form a reduced state transition metal compound. An electrochemical redox reaction is performed including the reduced state transition metal compound to regenerate the transition metal compound in an electrolyzer including a power source. During the electrochemical redox reaction a voltage from the power source applied to the electrolyzer is controlled to regenerate the transition metal compound at a rate sufficient to match a flow rate of hydrogen sulfide into the scrubber or maintain a predetermined maximum hydrogen sulfide level out from the scrubber. The transition metal compound regenerated is returned to the scrubber for the reacting.
