Sulphur Dioxide is a colorless, irritating, nonflammable, poisonous, liquefied gas transported under its own vapor pressure in cylinders, ton containers, or small (1,000–5,000 gallon) tanks. Itnaturally arises from volcanic occurences and is formed via the combustion of sulfur-containing hydrocarbons in the atmosphere. Commercial production is nearly always as a byproduct of other manufacturing; the method by which it’s generated is a function of demand for other products. A frequent source of sulfur dioxide has been the manufacture of calcium silicate cement from calcium sulfate and coke. It’s generally conceded that the most significant use of sulfur dioxide is in petroleum refining. Via the Claus Process, petroleum refiners produce elemental sulfur and water by adding sulfur dioxide to hydrocarbons containing hydrogen sulfide. From the dawn of ancient Roman wine production, sulfur dioxide has been employed widely to minimize the oxidation of fermenting spirits. The most frequent use of packaged quantities of sulfur dioxide continues to be as a preservative in the winemaking process. SO2 enjoys use also as preservative for dried fruits; it helps fruits to retain their color and reduces the growth of microorganisms. Back in time, before the synthesis and commercialization of chlorofluorocarbons in the 1930’s, sulfur dioxide, along with ammonia and methyl chloride, found extensive use in mechanical refrigeration. Anymore, SO2 is used also generate part-per-million-level calibration gas mixtures for the petrochemical industry and environmental emission monitoring.
