Oxygen is a colourless, odourless reactive gas and the life-sustaining component of air. It forms approximately 21% of the earth’s atmosphere. In addition to its use as a respiratory gas for healthcare applications, oxygen has strong oxidizing properties that can benefit many industries by improving yields, optimizing performance, lowering costs and reducing carbon footprint compared to other fuels. Oxygen enrichment or replacement of air also enhances chemical and biological process efficiency.

Applications using oxygen include combustion, oxidation, fermentation, wastewater treatment and aquaculture. Combined with acetylene (C₂H₂) or other fuel gases or with argon (Ar) and carbon dioxide (CO₂), oxygen is also used for metal cutting, welding, scarfing, hardening, cleaning, and melting applications.
