Air Separation Plant
Air Separation Plant

50~120000Nm3/h Air Separation Plants; 50~40000Nm3/h High-purity Nitrogen Generator; 10~1000TPD Oxygen and Nitrogen Liquefier, and 100~1000TPD Cold energy utilization liquid air separation plant; helium, neon, krypton and xenon full extraction plant.

Technical Features:
SASPG has developed extra large air separation plant of capacity of hundred thousand Nm3/h. SASPG could offer the optimized process according to client’s different requirements which includes low pressure molecular sieve adsorption (vertical radial flow) process, medium /low pressure booster turbo-expander cold generation process, product oxygen internal/external compression process, product nitrogen internal/external compression process, air/nitrogen pressurizing recycling process, liquid expander cold regeneration process, structured packing rectification process, without-using-hydrogen argon production process, rare gas full-recovery process and its automatic off-design load and optimizing control technology. The oxygen recovery rate reaches more than 99.6% and the argon recovery up to 80% while the lowest specific power consumption of oxygen is 0.34kw.h/Nm3. A number of independent innovation technology has been successfully applied in 40000~100000 Nm3/h air separation plants.
