Hydrogen Sulfide Supplier to Indianapolis Hydrogen Sulfide (H₂S), a colorless, flammable, toxic gas that reeks of rotten eggs, is normally viewed as a contaminant in natural gas. It does indeed have its uses, in any event – which is why American Welding & Gas, Inc. makes PurityPlus® Hydrogen Sulfide available at reasonable prices in Indianapolis. High levels of Hydrogen Sulfide can be extracted from “sour” natural gas fields to limit corrosion in collection and transmission pipeline systems, thus improving 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 by regulated oxidation. Relatively small quantities of H₂S are then dried and purified for commercial sale. Hydrogen Sulfide is sometimes used to create metal sulfides and as a reactive gas to synthesize high-purity mercaptans. It is frequently associated in error with the smell of commercial natural gas; typically natural gas is odorized with mixtures of ethyl, propyl, and butyl mercaptan to provide the “rotten egg” smell without the corrosion hazard of Hydrogen Sulfide in a moist setting. In the specialty gas field, H₂S is often a component in calibration gases for environmental emission and industrial hygiene control in the parts per million (ppm) range.
