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

In the equipment of oxygen production based on the principle of low-temperature distillation, in order to ensure the normal rectification and separation of air in the low-temperature area, the air must be pretreated in the normal temperature area, such as filtration, precooling and purification. The air contains a lot of dust. During the long-term high-speed operation of the air turbine compressor (hereinafter referred to as the air compressor)
