Exceptional Purity and a Low Environmental Footprint
INEOS Calabrian is the leading North American manufacturer of on-purpose sulfur dioxide. Its proprietary SO₂Clean® process has been successfully and safely applied for more than three decades with sites in Port Neches, Texas, and Timmins, Ontario. The conventional method for manufacturing SO2 is to burn sulfur using ambient air. Instead, INEOS Calabrian reacts sulfur and pure oxygen. Since pure oxygen is more sterile than ambient air, the SO₂Clean® process results in ultra-pure SO2. The efficiency of the SO₂Clean® process helps companies meet rising corporate responsibility and sustainability targets.See our history
