Sulfur Dioxide Supplier to Winona

Mississippi Welders Supply Co., Inc. is a respected provider of Sulfur Dioxide (SO2) to various enterprises in Winona.

Sulphur Dioxide is a colorless, irritating, nonflammable, lethal, liquefied gas shipped under its own vapor pressure in cylinders, ton containers, or small (1,000–5,000 gallon) tanks. Sulfur dioxide is created in nature, most especially as a result of volcanic eruptions, when hydrocarbons containing sulfur ignite in the atmosphere. Commercial production is pretty much exclusively as a byproduct of other manufacturing; the method by which it’s generated is 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.

Probably the most significant use of sulfur dioxide is in petroleum refining. By means of the Claus Process, petroleum refiners end up with elemental sulfur and water when they mix sulfur dioxide with hydrocarbons that also contain hydrogen sulfide.

From the dawn of ancient Roman wine production, sulfur dioxide has been employed widely to reduce the oxidation of fermenting spirits. The largest use of packaged amounts of sulfur dioxide continues to be as a preservative in the winemaking process. SO2 is popular also as preservative for dried fruits; it helps fruits to hold on to their color and inhibits the reproduction 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.

Anymore, SO2 is used also produce part-per-million-level calibration gas mixtures for the petrochemical industry and environmental emission monitoring.
