Fresno Oxygen & Welding Supplies/Barnes Welding Supply is a dependable supplier of Sulfur Dioxide (SO2) to a number of enterprises across this area surrounding and including Fresno.

Sulphur Dioxide is a colorless, irritating, nonflammable, lethal, liquefied gas delivered under its own vapor pressure in cylinders, ton containers, or small (1,000–5,000 gallon) tanks. Sulfur dioxide shows up in nature, most especially as a result of volcanic eruptions, when hydrocarbons containing sulfur combust in the atmosphere. Commercial production is nearly always as a byproduct of other manufacturing, the process by which it’s created being a matter of the demand for other products. A source most often relied upon for sulfur dioxide has been the creation of calcium silicate cement from calcium sulfate and coke.

It’s generally conceded that the largest 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 that also contain hydrogen sulfide.

Ever since wine production was first documented by the ancient Romans, sulfur dioxide has been applied extensively to control the oxidation of fermenting spirits. The most frequent use of packaged amounts 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 hold on to their color and reduces the growth of microorganisms.

At one time, before the synthesis and commercialization of chlorofluorocarbons in the 1930’s, sulfur dioxide, ammonia, and methyl chloride all found extensive use in mechanical refrigeration.

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