Hydrogen Sulfide Oxidation by Chlorine

H2S + Cl2 → 2HCl + S

Übersicht

Chlorine oxidizes hydrogen sulfide to elemental sulfur while being reduced to hydrochloric acid. Sulfur is oxidized from -2 to 0. This reaction is used in removing hydrogen sulfide from natural gas (sweetening) and in treating hydrogen sulfide-containing wastewater.

Alltägliches Beispiel

The rotten egg smell of hydrogen sulfide from sewers can be eliminated by chlorination, which oxidizes H₂S to odorless elemental sulfur.

Industrielle Bedeutung

H₂S removal by chlorine oxidation is used in natural gas sweetening, wastewater treatment, and in the petroleum refining industry.
