Liquid Oxygen Plant With Air Separation

Liquid Oxygen Plant With Air Separation

The Liquid Oxygen Plant with Air Separation is an integrated, high-efficiency system that combines advanced air separation technology with liquid oxygen production, liquefaction, and storage. Leveraging NEWTEK’s core technologies of PSA (Pressure Swing Adsorption) and Cryogenic Separation, it extracts oxygen from ambient air through precise purification, rectification, and liquefaction processes, delivering liquid oxygen (LOX) with purity ranging from 95% to 99.9995%. The plant features scalable capacity (50 Nm³/h to 50,000 Nm³/h) and integrates key components such as air compressors, molecular sieve purification systems, cryogenic rectification towers, and vacuum-insulated storage tanks. Compliant with international standards (ISO, CE, ASME), it is designed for stable, continuous operation, catering to diverse industrial, medical, and special scenario needs while eliminating dependencies on external oxygen supply chains.

China Liquid Oxygen Plant With Air Separation
working principle
 
 
 

Air Preprocessing

Ambient air is compressed and filtered to remove dust, oil, and moisture, protecting subsequent core components.

 
 

PSA Adsorption Purification

Molecular sieves in dual towers selectively adsorb nitrogen and impurities, enabling continuous production of 90%-95% pure oxygen.

 
 

Cryogenic Separation & Liquefaction

Oxygen-rich gas is cooled to -170℃~-196℃; cryogenic rectification separates residual nitrogen by boiling point differences, condensing pure oxygen into liquid oxygen (LOX).

 
 

Storage & Output Regulation

LOX is stored in vacuum-insulated tanks; vaporized into gaseous oxygen or directly output as LOX on demand, with PLC real-time monitoring and parameter adjustment.
