Sulfur Dioxide Supplier to Portland

Cryo-Source is a valued provider of Sulfur Dioxide (SO2) to many commercial customers across the Portland market.

Sulphur Dioxide is a colorless, irritating, nonflammable, lethal, liquefied gas transported under its own vapor pressure in cylinders, ton containers, or small (1,000–5,000 gallon) tanks. It’s a natural by-product of volcanic occurences and is produced by the combustion of sulfur-containing hydrocarbons in the atmosphere. Commercial production is nearly always as a byproduct of other manufacturing, the technique for producing it being a function of demand for other products. A source most often relied upon for sulfur dioxide has been the production of calcium silicate cement from calcium sulfate and coke.

Undoubtedly 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 hydrogen-sulfide-containing hydrocarbons.

Ever since wine production was first documented by the ancient Romans, sulfur dioxide has been used widely to minimize the oxidation of fermenting spirits. The largest use of packaged quantities of sulfur dioxide remains as a preservative in the winemaking process. SO2 is equally sought as preservative for dried fruits; it helps fruits to hold on to their color and reduces the growth of microorganisms.

In the old days, before 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 generate part-per-million-level calibration gas mixtures for the petrochemical industry and environmental emission monitoring.
