Industrial gases refer to oxygen, nitrogen, argon, neon, helium, krypton, xenon, hydrogen, carbon dioxide, acetylene, natural gas, etc. Due to their inherent physical and chemical properties, these gases occupy a pivotal position in the national economy, and their popularization and application are very fast, penetrating into almost all walks of life. As an important basic material of modern industry, gas products have a wide range of applications, and a large number of commonly used gases or special gases are used in metallurgy, steel, petroleum, chemical industry, machinery, electronics, glass, ceramics, building materials, construction, food processing, medicine and medical treatment.
The traditional industries with a large amount of industrial gases include: steelmaking, ironmaking, non-ferrous metal smelting, fertilizer production, ethylene, propylene, polyvinyl chloride, man-made fibers, synthetic fibers, silicone rubber products, cables and synthetic leather and other petrochemical industries, machinery industry production welding, metal heat treatment, helium leakage, float glass production, etc. Due to the rapid development of these traditional industries in recent years, the consumption of industrial gases has also reached a peak.
The industries in which the amount of industrial gases are being excavated are: coal mine fire extinguishing, oil exploitation, coal gasification and coal liquefaction, glass melting furnaces, cement production kilns, refractory production kilns, brick kilns and other industrial furnaces, food quick-freezing, food modified atmosphere packaging, beer preservation, optics, fuel in the production of national defense industry, superconducting material production, electronics, semiconductors, optical fiber production, agriculture, animal husbandry, fish, wastewater treatment, bleaching pulp, garbage incineration, crushing waste tires and other environmental protection industries, construction, meteorology, culture, cultural relics protection, Sports, public security crimes, cold knives in the health care industry, oxygen inhalation for critically ill patients, hyperbaric oxygen therapy, low-temperature refrigeration of human organs, anesthesia technology and oxygen bar, etc.
The industries in which industrial gas applications are being tested are: solid nitrogen production, fuel cell production, magnetic material production, ultrafine processing, natural gas power generation, compressed natural gas vehicles, hydrogen energy vehicle production, etc.
Industries with a large amount of industrial gases, such as steel, fertilizer, chemical, glass and chemical fiber industries, have built their own gas production equipment and implemented the business policy of self-production and self-sale, while some industries with less industrial gas consumption mainly rely on the market to purchase industrial gases.
