source
Oxygen is obtained by liquefaction and distillation of air. For very high-purity oxygen, it usually needs to be extracted from the air separation equipment through secondary purification and distillation. Or it can also produce high-purity oxygen through Electrolysis of water
application
Many oxidation reactions in the chemical industry use pure oxygen instead of air to benefit from higher reaction rates, easier product separation, and larger or smaller equipment sizes
2. High purity oxygen is used to form silicon dioxide and metal oxides, as a corrosive agent for photoresists, and mixed with halogenated carbon for etching silicon
Oxygen and hydrogen are used together for fuel torch welding, glass blowing, and tube sealing, in various electronic components such as relay switches
4. In advanced gas cooled nuclear reactors, pure oxygen is used together with high-purity methane to maintain an appropriate carbon balance in the core gas coolant
5. High purity oxygen used in fiber optic production process
6. Inject oxygen into the sewage treatment pool to accelerate sewage decomposition
7. Oxygen for chemical synthesis
8. Oxygen is used as an oxidant
9. Oxygen is a burner used to supplement or replace air in many different industries to increase temperature. Typical applications in industries such as steel, non-ferrous metals, glass, and concrete
10. Oxygen used for flame sealing of glass bottles in pharmaceutical and chemical industries
11. In the food industry, oxygen is used to transport live fish and seafood
During the fermentation process, oxygen is used to increase the content of air
13. After mixing with other gases, oxygen can be used to create breathable gases (oxygen+carbon dioxide, regeneration; oxygen+helium or oxygen+nitrogen, diving)
14. In some cases, oxygen can be used as a gas conditioning package for food, and pure oxygen can also be mixed with carbon dioxide or nitrogen for use
15. Liquid oxygen is used to manufacture liquid oxygen explosives and as fuel in space propulsion
16. Oxygen is used as a pure gas and mixture in the medical field
17. Oxygen is also used for calibration gases
18. Oxygen for Metal Laser Processing Applications
19. Oxygen for cutting and welding
