Hydrogen Sulfide Supplier to St. Louis Hydrogen Sulfide (H₂S), a colorless, flammable, toxic gas that smells like rotten eggs, is typically considered a contaminant in natural gas. It most definitely has its uses, though – which is the reason Cee Kay Supply, Inc. makes PurityPlus® Hydrogen Sulfide available at affordable prices in St. Louis. High levels of Hydrogen Sulfide are commonly removed from “sour” natural gas fields to cut corrosion in collection and transmission pipeline systems, which improves the natural gas’s heat content and transforming it to make it more commercially viable. The collected Hydrogen Sulfide is generally converted to elemental sulfur via controlled oxidation. Relatively small quantities of H₂S are then dried and purified for commercial sale. Hydrogen Sulfide may be used to form metal sulfides and as a reactive gas to synthesize high-purity mercaptans. It is commonly associated by mistake with the smell of commercial natural gas; typically natural gas is odorized with mixtures of ethyl, propyl, and butyl mercaptan to create the “rotten egg” smell without the corrosion hazard of Hydrogen Sulfide in a moist application. In the specialty gas market, H₂S is often a component in calibration gases for environmental emission and industrial hygiene regulation in the parts per million (ppm) range.
