Sulfur dioxide (SO2)

Sulfur Dioxide (SO2)

Sulfur dioxide (SO2) is available in a liquefied form, under pressure.

Unlike other manufacturers who produce SO2 using a sulfur burner, Calabrian's proprietary production process generates high purity on-purpose sulfur dioxide by the reaction of pure oxygen with sulfur. This unique closed loop design supports a more efficient and environmentally friendly production process.

Applications

  • - Dechlorination in municipal wastewater, pulp & paper, power, and textile water treatment plants
  • - Oxygen scavenger
  • - Preservative
  • - Reducing agent
  • - Sanitizer
  • - Used in production of cleaning agents, detergents, and soaps
  • - Intermediate to sulfur trioxide, oleum and sulfuric acid
