Sulfur Dioxide Supplier to Minneapolis Toll Company is a respected supplier of Sulfur Dioxide (SO2) to a number of commercial customers throughout the Minneapolis area. 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 is created in nature, most obviously as a result of volcanic activity, when hydrocarbons containing sulfur combust in the atmosphere. Commercial production is pretty much exclusively as a byproduct of other manufacturing; the methodology of its generation is a matter of the demand for other products. A source most often relied upon for 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. By means of the Claus Process, petroleum refiners produce elemental sulfur and water by adding sulfur dioxide to hydrocarbons that also contain hydrogen sulfide. Since the ancient Romans first set down their wine production techniques, sulfur dioxide has been employed extensively to control the oxidation of fermenting spirits. The largest use of packaged quantities of sulfur dioxide remains as a preservative applied in the process of making wine. SO2 enjoys use also as preservative for dried fruits; it helps fruits to retain their color and inhibits the reproduction of microorganisms. Earlier on, before the synthesis and commercialization of chlorofluorocarbons in the 1930’s, sulfur dioxide, along with ammonia and methyl chloride, found wide use in mechanical refrigeration. Nowadays, SO2 is used also generate part-per-million-level calibration gas mixtures for the petrochemical industry and environmental emission monitoring.
