Air separation plants separate atmospheric air into its main components, usually nitrogen and oxygen, and sometimes argon and other rare and inert gases.The most common method of air separation is fractional distillation. Cryogenic Air Separation Units (ASUs) are used to supply nitrogen or oxygen an

Pressure swing adsorption separates oxygen or nitrogen from air without liquefaction. The process operates at ambient temperature; the zeolite (molecular sponge) is exposed to high-pressure air, which then releases the air and releases an adsorbed film of the desired gas. Compressors are greatly red

The production scale of China's air separation equipment has changed from the early stage, which can only produce 20m3 / h (oxygen) oxygen generator. It has developed to the capacity of producing 20000 m3 / h, 30000 m3 / h, 50000 m3 / h and 60000m3 / h large-scale air separation equipment, and has completed the scientific research stage and is about to manufacture 80000m3 / h ultra large-scale air separation equipment.
