SO₂ Industrial Gas, or Sulfur Dioxide, is a highly important industrial gas widely used in chemical manufacturing, environmental control, water treatment, and food processing. Its reactive and oxidizing properties make it an essential gas for modern industries requiring chemical synthesis, sterilization, or environmental applications.
Industrial users prefer SO₂ Industrial Gas for its high purity, predictable performance, and reliable supply, ensuring safe and efficient operation across multiple sectors.
Sulfur Dioxide (SO₂) is a colorless, non-flammable gas with a pungent, suffocating odor. It is highly soluble in water, forming sulfurous acid, which is widely used in industrial processes.
Key properties of industrial-grade SO₂ gas:
Chemical formula: SO₂
CAS No.: 7446-09-5
Physical state: Gas at room temperature
Odor: Sharp, pungent
Purity: ≥ 99.5% for industrial applications
Storage: High-pressure cylinders or bulk tanks
