Sulfur Dioxide Supplier to Springfield ILMO Products Company is a dependable distributor of Sulfur Dioxide (SO2) to various enterprises across this region surrounding and incorporating Springfield. 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 a natural by-product of volcanic occurences and is produced by the combustion of sulfur-containing hydrocarbons in the atmosphere. Commercial production is pretty much exclusively as a byproduct of other manufacturing; the method by which it’s generated is dependent upon the call for other products. A source most often relied upon for sulfur dioxide has been the manufacture of calcium silicate cement from calcium sulfate and coke. Arguably the greatest use of sulfur dioxide is in petroleum refining. By means of the Claus Process, petroleum refiners produce elemental sulfur and water by adding sulfur dioxide to hydrogen-sulfide-containing hydrocarbons. From the dawn of ancient Roman wine production, sulfur dioxide has been employed almost universally to reduce the oxidation of fermenting spirits. The most frequent use of packaged amounts of sulfur dioxide remains as a preservative in winemaking. SO2 is equally sought as preservative for dried fruits; it enables fruits to keep their color and thwarts the excessive growth of microorganisms. At one time, prior to the synthesis and commercialization of chlorofluorocarbons in the 1930’s, sulfur dioxide, along with ammonia and methyl chloride, found extensive use in mechanical refrigeration. These days, SO2 is used as well generate part-per-million-level calibration gas mixtures for the petrochemical industry and environmental emission monitoring.
