Sulfur Dioxide Supplier to Sioux Falls

A-OX Welding Supply is a much relied-upon distributor of Sulfur Dioxide (SO2) to a diverse cross-section of enterprises in this market surrounding and including Sioux Falls.

Sulphur Dioxide is a colorless, irritating, nonflammable, poisonous, liquefied gas delivered under its own vapor pressure in cylinders, ton containers, or small (1,000–5,000 gallon) tanks. It’s when sulfur-containing hydrocarbons [[combust|catch fire|ignite]19} in the atmosphere – a typical event during volcanic activity – that sulfur dioxide is created naturally. Commercial production is pretty much exclusively as a byproduct of other manufacturing, the process by which it’s created being dependent upon the call for other products. A frequent source of sulfur dioxide has been the creation of calcium silicate cement from calcium sulfate and coke.

Undoubtedly the greatest use of sulfur dioxide is in petroleum refining. Through the Claus Process, petroleum refiners produce elemental sulfur and water by adding sulfur dioxide to hydrocarbons containing hydrogen sulfide.

Ever since wine production was first documented by the ancient Romans, sulfur dioxide has been employed extensively to reduce the oxidation of fermenting spirits. The most frequent use of packaged sulfur dioxide remains as a preservative in winemaking. SO2 is popular also as preservative for dried fruits; it allows fruits to keep their color and inhibits the reproduction of microorganisms.

Earlier on, predating the synthesis and commercialization of chlorofluorocarbons in the 1930’s, sulfur dioxide, as well as ammonia and methyl chloride, found widespread use in mechanical refrigeration.

As it is now, SO2 is further used make part-per-million-level calibration gas mixtures for the petrochemical industry and environmental emission monitoring.
