>Technical Features
On the basis of introducing and learning the advanced technology from home and abroad and independent research & development, SASPG has developed 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 40000~60000 Nm3/h air separation plants. SASPG has made eye-catching progress in large and medium-sized air separation plant design and manufacturing and has obtained well-proven, complete and advanced air separation technologies with its own special characteristics.
