5, in natural gas reforming production of methanol, ethylene, propylene oxidation production of their oxides, desulfurization and recovery, also need to consume a lot of oxygen.

6. In the pressurized coal gasification, in order to maintain the temperature of the oxide layer in the furnace, sufficient oxygen must be supplied. The purity of oxygen is not less than 95%, and the oxygen consumption per kilogram of coal varies with different kinds of coal and coal quality. The oxygen pressure is determined by the production process requirements, the higher the pressure, the less oxygen consumption.

7, the supply of breathing: used for hypoxia, hypoxia or anaerobic environment, such as: diving operations, mountaineering, high-altitude flight, space navigation, patient first aid and auxiliary treatment of indispensable substances.

8, oxygen can also support combustion, often used in metal cutting and welding and other aspects. Oxygen acts as an accelerant to acetylene to produce a high temperature flame that melts metals.

9. The mining, production, and creation of stone and glass products require large amounts of oxygen.

10. Gases necessary for plants to breathe.

11, commonly used as a catalyst, can react with other chemical substances, widely used in chemical experiments.

12, now people's material and spiritual life is greatly enriched, oxygen bar gradually developed, so that people living in a busy city can sit down, take oxygen to rest, relax and adjust.

Oxygen is the source of life, now oxygen is widely used in various fields, oxygen production has become an indispensable part of the national economy. Xiaobian just lists some more extensive uses, of course, there are a lot of unknown to be discovered.
