SULFUR DIOXIDE, WET Chemical compatibility with O-rings, rubbers, & plastics

Wet sulfur dioxide is a colorless gas with a pungent odor, having the chemical formula SO2, and contains moisture. It is used in various industrial and chemical applications primarily as a preservative, bleaching agent, and intermediate in the production of sulfuric acid. In the food industry, wet sulfur dioxide is employed as a preservative for dried fruits, wines, and other food products, preventing spoilage and maintaining freshness. It is also used in the pulp and paper industry for bleaching wood pulp and in water treatment processes for dechlorination. Proper handling and storage of wet sulfur dioxide are essential to prevent accidents and ensure safety, as it is highly toxic and can cause respiratory irritation and other health hazards. Safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are crucial when working with wet sulfur dioxide. Its versatility and effectiveness in various applications make wet sulfur dioxide a valuable chemical in numerous industries, although its use requires careful control to prevent hazards.
