Industrial gases refer to gases widely used in industrial production and applications. They mainly include the following:
1. Nitrogen (N₂): used for gas protection, cooling and as an inert gas to prevent oxidation.
2. Oxygen (O₂): used for welding, cutting and breathing equipment, and can also be used in medical and water treatment.
3. Helium (He): used to fill balloons, as a coolant and used in nuclear magnetic resonance.
4. Argon (Ar): mainly used in welding and metal cutting, as an atmosphere gas to prevent metal oxidation.
5. Carbon dioxide (CO₂): used for dry ice manufacturing, carbonated beverages and protective gas during welding.
6. Hydrogen (H₂): used for synthetic ammonia, hydrogen fuel cells and as a reducing agent for hydrogenation reactions.
Use: Industrial gases play an important role in the manufacturing industry, such as welding, cutting, metallurgy, fertilizer production and medical fields.
Production: These gases are usually obtained through air separation technology, chemical reactions or physical methods. Air separation plants extract nitrogen, oxygen and argon through cryogenic separation or membrane separation technology.
Safety measures: Strict safety regulations must be followed when handling industrial gases, including prevention of gas leaks, appropriate storage conditions, use of appropriate personal protective equipment, and regular inspection of equipment to ensure safe operation.
