With the rapid development of China’s economy, the importance and role of industrial gases in the economy have become increasingly prominent. As an important basic raw material for modern industry, gas products have a wide range of applications.
Industrial gases mainly include oxygen, nitrogen, argon, helium, neon, krypton, xenon, hydrogen, carbon dioxide, acetylene, natural gas, etc., involving all aspects of industry. The industrial gases mentioned in this paper mainly refer to the ability to separate and obtain oxygen, nitrogen, and argon through air filtration equipment. Rare gases such as helium and neon can also be obtained by further purification.
Preparation of oxygen, nitrogen, and argon is mainly achieved through air separation equipment. Large-scale air separation equipment is mainly used in coal chemical, fertilizer, petrochemical, metallurgical industries, and IGCC power generation enterprises, while small and medium-sized air separation equipment is mainly used for small and medium-sized metallurgy, Chemicals, building materials, electronics companies.
At present, there are two models for large-scale industrial gas use in China: one is for self-construction, air separation equipment companies only provide equipment, and the other is for outsourcing model, which directly allows air separation equipment companies to invest and build factories in the plant area. Provide gas for the company. With the strengthening of industrial gas market, more and more outsourcing models will be applied.
