Sulfur Dioxide Supplier to Mexico AOC Mexico S.A. de C.V. is a valued provider of Sulfur Dioxide (SO2) to quite a few businesses across this region surrounding and incorporating Mexico. 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. It’s when sulfur-containing hydrocarbons [[combust|catch fire|ignite]19} in the atmosphere – a typical event during volcanic activity – that sulfur dioxide manifests itself naturally. Commercial production is almost unfailingly as a byproduct of other manufacturing; the method by which it’s generated is a matter of the demand for other products. One of the most common sources of sulfur dioxide has been the creation 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. Through 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 applied widely to control the oxidation of fermenting spirits. The most generally accepted use of packaged amounts of sulfur dioxide is still as a preservative applied in the process of making wine. SO2 is equally sought as preservative for dried fruits; it allows fruits to keep their color and thwarts the excessive growth of microorganisms. At one time, predating the synthesis and commercialization of chlorofluorocarbons in the 1930’s, sulfur dioxide, as well as ammonia and methyl chloride, found extensive use in mechanical refrigeration. As it is now, SO2 is further used produce part-per-million-level calibration gas mixtures for the petrochemical industry and environmental emission monitoring.
