Abstract
A method and system for separating hydrogen and sulfur from hydrogen sulfide(H,S) gas being produced from oil and gas waste streams. The hydrogen sulfide(H,S) gas is first passed into a scrubber and filtration unit where it encounters polysulfide solution. Elemental sulfur is freed when the H,S interacts with the solution, the sulfur is filtered through a porous media such as a ceramic frit, and continues to a stripper unit where the excess H,S is removed from the sulfide solution. The excess H,S returns to the scrubber and filtration unit, while the sulfide solution passes into a photoreactor containing a semiconductor photocatalyst such as Cadmium Sulfide(CdS), Platinized Cadmium Sulfide, Pt-CdS, Zinc Sulfide, ZnS, Zinc Ferrate, ZnFe,O,, Indium Sulfide, In,S,, along with a 450-500 nm light source.
