Sulphur Dioxide is a colorless, irritating, nonflammable, toxic, liquefied gas transported 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 common event during volcanic activity – that sulfur dioxide manifests itself naturally. Commercial production is almost always as a byproduct of other manufacturing, the technique for producing it being a function of demand for other products. A source most often relied upon for sulfur dioxide has been the production of calcium silicate cement from calcium sulfate and coke.

Arguably the greatest use of sulfur dioxide is in petroleum refining. Via the Claus Process, petroleum refiners create elemental sulfur and water by adding sulfur dioxide to hydrocarbons that also contain hydrogen sulfide.

Ever since wine production was first documented by the ancient Romans, sulfur dioxide has been employed extensively to control the oxidation of fermenting spirits. The largest use of packaged amounts of sulfur dioxide remains as a preservative applied in the process of making wine. SO2 is popular also as preservative for dried fruits; it enables fruits to hold on to their color and reduces the growth of microorganisms.

In the old days, 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 used as well generate part-per-million-level calibration gas mixtures for the petrochemical industry and environmental emission monitoring.
