Sulfur Dioxide Supplier to Auburn

Spec Air Specialty Gases is a respected distributor of Sulfur Dioxide (SO2) to a number of businesses across Auburn.

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 noticeably as a result of volcanic occurrences, when hydrocarbons containing sulfur catch fire in the atmosphere. Commercial production is almost 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 production of calcium silicate cement from calcium sulfate and coke.

Arguably the most significant use of sulfur dioxide is in petroleum refining. Via the Claus Process, petroleum refiners end up with elemental sulfur and water when they mix sulfur dioxide with hydrogen-sulfide-containing hydrocarbons.

Ever since wine production was first documented by the ancient Romans, sulfur dioxide has been employed widely to control the oxidation of fermenting spirits. The largest use of packaged quantities of sulfur dioxide remains as a preservative in the winemaking process. SO2 is popular also as preservative for dried fruits; it allows fruits to keep their color and thwarts the excessive growth of microorganisms.

Earlier on, prior to the synthesis and commercialization of chlorofluorocarbons in the 1930’s, sulfur dioxide, as well as ammonia and methyl chloride, found widespread use in mechanical refrigeration.

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