Industrial gas
From Wikipedia, the free encyclopedia
Industrial gas is a group of gases that are commercially manufactured and sold for uses in other applications. These gases are mainly used in an industrial processes, such as steelmaking, medical applications, fertilizer, semiconductors, etc,. They may be both organic and inorganic, are produced by extraction from the air by a process of separation or are produced by chemical synthesis, and will take various forms such as compressed, liquid, or solid.
Types of industrial gases:
- acetylene (C2H2)
- carbon dioxide (CO2)
- carbon monoxide (CO)
- chlorine (Cl2)
- hydrogen (H2)
- hydrogen chloride (HCl)
- methane (CH4)
- nitrous oxide (N2O)
- propane (C3H8)
- sulphur dioxide (SO2)
- Air gases
- Rare gases
Applications:
- Chemical industry
- Cutting and welding
- Environmental protection
- Food
- Gases for breathing
- Gases for safety and inerting
- Glass, ceramics, other minerals
- Medicinal gases
- Metallurgy
- Rubber, plastics, paint
- Semiconductor industry
- Water treatment
Distribution:
- Pipelines
- Bulk transport (truck, rail, ship)
- Cylinders (welding-acetylene torch, breathing, soda fountain)
