1.What are industrial gases?
As we all know, industry is indispensable in our lives. All countries must go through industrial baptism to reach the era of scientific and technological civilization. The development of science and technology must be achieved through industrial smelting, so industrial gases are the basis of industry. So what are industrial gases?
Industrial gases refer to gaseous substances widely used in industrial production processes. They are usually produced through air separation, chemical reactions or other technologies and have specific purity and physical and chemical properties.
Following are the classifications of industrial gases:
| Bulk gas (general purpose gas) | Oxygen (O2) | Used for metal welding, medical first aid: sewage treatment, etc. |
| Ammonia (N2) | Used as protective gas (such as electronics industry) food preservation, liquid nitrogen freezing, etc. | |
| Argon (Ar) | Inert gas, used for welding protection semiconductor manufacturing. | |
| Carbon dioxide (CO2) | Beverage carbonation, welding protection, plant greenhouse fertilization. | |
| Special gases (high purity or mixed gases) | Electronic gases | Such as high purity ammonia (NH3) and sulfur hexafluoride (SF6), used in chip and LCD panel manufacturing. |
| Medical gases | Such as laughing gas (N20) and medical oxygen. | |
| Laser gases | Such as helium-neon (He-Ne) mixed gases. | |
| Combustible gases | Hydrogen (H2) | Used in petrochemicals, fuel cells, semiconductor reduction. |
| Acetylene (C2H2) | Metal cutting and welding. | |
| Rare gases | Helium (He), neon (Ne), krypton (Kr), xenon (Xe) | Used in lighting, lasers, aerospace and other fields. |
2. The role of industrial gases.
2.1 Oxygen (O2)
The role of oxygen is the most well-known, because people need oxygen to live, so it is conceivable that it plays a very important role in the medical field. But do you know what other industries are involved?
Oxygen is a colorless, odorless, tasteless gas that can sustain life and make combustion possible. It is also the most widely used industrial gas. Its high reactivity and combustion-supporting properties play a variety of roles in the industrial field, such as steel smelting, non-ferrous metal smelting, welding and cutting, semiconductor manufacturing, optical fiber preforms, aerospace as liquid oxygen as a propellant, and food industry oxygenation to prolong the color of meat.
2.2 Ammonia (N2)
Ammonia is a highly irritating colorless gas that is easily soluble in water. It is an important chemical raw material and an emerging clean energy source.
It is most commonly used as a fertilizer and is known as the “pillar of global food security.” As a basic chemical raw material, gunpowder is used in explosives and nylon production, and can also be used as a refrigerant. Other uses include pharmaceuticals, dyes, and the semiconductor industry (CVD process).
2.3 Argon (Ar)
Argon is a colorless, odorless, non-toxic inert gas with stable chemical properties. It is used in argon arc welding (TIG/MIG welding), laser cutting, metal smelting, semiconductor production, laser technology, argon and argon-helium knives, as well as respiratory therapy, food preservation and wine protection, 3D printing and other technologies.Argon is widely used in daily life and is in high demand.
2.4 Carbon dioxide (CO2)
Carbon dioxide is mainly used as a pH control agent for water treatment, welding gas, plant growth stimulant, hardened film and core pneumatic devices in the casting process, etc. It can also be used as a bactericide. The application range of carbon dioxide in industry is relatively wide, and it is also the main application direction of carbon dioxide at present. In the food industry, carbon dioxide can be used as an additive for carbonated beverages and beer, an inert protective gas in the food processing process, and a refrigerator in food transportation.
2.5 Electronic gases
Electronic gases are generally referred to as electronic gases, which refer to high-purity gases used in the production of semiconductors and other electronic products. With the development of the microelectronics industry, the relationship between the purity of electronic gases and product quality is becoming increasingly close. They are widely used in electronic industries such as large-scale integrated circuits, liquid crystal displays, polysilicon and thin-film solar cells, new electric light sources, optoelectronic semiconductor devices, and optical fiber communication devices.
2.6 Medical gases
Medical air is compressed by a special air compressor. The air is passed through a dryer to maintain the correct dew point and then delivered to the required medical space. In small medical institutions, medical air can also be supplied by high-pressure gas cylinders. The gas pressure is maintained at 345-380 kPa (50-55 psi).

2.7 Laser gases
Gas lasers are used for gas or gas mixtures as working media of lasers, and are applied in the fields of industry, medicine, scientific research and environmental protection.
They can be used for laser cutting and welding, laser marking and engraving, and 3D printing. In medicine, laser surgery can be performed, and laser gas analyzers are used for medical diagnosis. They can also be used in lithography technology and wafer processing in semiconductors. In scientific research, they can be used for nuclear fusion research and laser weapons, etc.
2.8 Hydrogen (H2)
Hydrogen has many potential uses.
Hydrogen can be used in industrial processes, as rocket fuel, and to generate electricity, power industrial power and vehicles, and heat homes and businesses.
It is very challenging for suppliers of natural gas power plants to explore the use of hydrogen as a supplement or substitute for natural gas.

2.9 Acetylene (C2H2)
Acetylene is used in welding and cutting processes. The welding process using acetylene is known as cutting oxy-fuel or cutting coal. This method is used for cutting or welding materials which require temperatures of up to 3,500 ° C (6,330 ° F). Acetylene is capable of producing the hottest flame of all other gases.
2.9 Rare gases
Most noble gases are very stable, so their ionization energy is very high. This makes them ideal for use as ion beam sources for cleaning, cutting or welding materials. They can also generate light. This minimizes the risk of contamination and increases the safety of industrial processes.
