Air separation plant is a complete set of the plant using air as raw meterial which separates nitrogen and oxygen by means of cryogenic rectification. From the liquified air formed with deep refrigeration.

Industry oxygen process consists of deep refrigeration and circulation with medium pressure reciprocationg expander, normal temperature molecular sieve adsorption and double - stage rectification.

The plant completely of oxygen for medical according to the principle of refrigeration and circulation of the highefficiency. Turbine Expander, Liquid oxygen pump replace oxygen compressor improve purity of oxygen, achieve state standard of medical oxygen.

This plant is featured by its simple process, advanced design, complete technigue, safe running and rational construction etc. It is widely used for chemical fibre, electronics, metallurgical oxygen for medical and glass fields.
