Abstract
Method of producing hydrogen sulfide in an alkaline environment. A mixture having a sodium salt, elemental sulfur (S) and water is added to a reactor for the purpose of generating hydrogen sulfide (H2S) gas as the main product and sodium sulfate (Na2SO4) as a byproduct.
Claims20
A method for producing hydrogen sulfide (H2S) gas, the method comprising:
- placing elemental sulfur and a sodium salt solution comprising a sodium salt in water in a reaction vessel;
- reacting the elemental sulfur with the sodium salt solution to form hydrogen sulfide (H2S) and sodium sulfate (Na2SO4);
- removing the formed Na2SO4 from the reaction vessel;
- crystallizing the Na2SO4 using a crystallizer;
- reducing the crystallized Na2SO4 to produce Na2S;
- forming a Na2S solution with the produced Na2S;
- placing elemental sulfur and the Na2S solution in the reaction vessel;
- and
- reacting the elemental sulfur with the Na2S solution to form hydrogen sulfide and sodium sulfate.
