  • Systems and processes for removing hydrogen sulfide from gas streams
    Patent number: 10246330
    Abstract: A process and system for hydrogen sulfide capture from gas streams employing an absorber vessel in which the gas stream containing hydrogen sulfide is contacted with an absorbent solution to remove the hydrogen sulfide from the gas stream. The process and system may further employ an oxidation vessel in which sulfides and/or bisulfides in the absorbent solution are oxidized to produce a thiosulfate and/or sulfate, yielding a solution that can be used as fertilizer or other applications.
    Type: Grant
