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

Strictly speaking, the heat exchange system is designed with multi stream mixed media in the same heat exchanger, so that the heat transfer of each medium is automatically balanced and the energy consumption is the lowest. However, for the internal compression process, all heat exchangers will be high-pressure heat exchangers, which will increase the accumulation of investment.

The adsorbers used in the purification system include vertical axial flow, horizontal double bed and vertical radial flow. Vertical axial flow is mainly used for supporting air separation equipment below 10000 grade (with a diameter of 4.6m). The bed thickness is 1550 ∽ 2300mm. It can be arranged in double layers and single layers. The vertical axial flow adsorber has the best air distribution.
