Sulfur Dioxide (SO2)

Unlike other manufacturers who produce SO₂ using a sulfur burner, INEOS Calabrian's proprietary production process generates ultra-pure 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.

Both sites offer rail car and truckload deliveries.
