Sulfur Dioxide Supplier to Denver Rocky Mountain Air Solutions is a much relied-upon distributor of Sulfur Dioxide (SO2) to many commercial customers throughout Denver. Sulphur Dioxide is a colorless, irritating, nonflammable, toxic, liquefied gas shipped 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 methodology of its generation is a function of demand for other products. A frequent source of sulfur dioxide has been the creation of calcium silicate cement from calcium sulfate and coke. Arguably the largest 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. From the dawn of ancient Roman wine production, sulfur dioxide has been employed extensively to minimize the oxidation of fermenting spirits. The most frequent use of packaged amounts 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 thwarts the excessive growth of microorganisms. In the old days, prior to the synthesis and commercialization of chlorofluorocarbons in the 1930’s, sulfur dioxide, ammonia, and methyl chloride all found widespread use in mechanical refrigeration. As it is now, SO2 is further used generate part-per-million-level calibration gas mixtures for the petrochemical industry and environmental emission monitoring.
