High-purity Nitrogen Air Separation Plant with Cpacity of 8000Nm3/h
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 including 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%. 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.
This air separation plant to be supplied by SASPG is a complete set of apparatus with the turbo-expander unit and normal temperature molecular sieve adsorption system.
A detailed brochure is attached with our offer which includes our company organization, structures and capabilities, a brief introduction to SASPG follows:
| Product | Output(Nm³/h) | Purity (volume) | Pressure Bar(g) (battery limit) |
| GAN | 8000 | ≤1ppmO2 V | 8 |
| LIN | 400 | ≤1ppmO2 V | 6.5 |
(1) Nm³/h means volume flow under 0℃, 0.1013MPa (A), which is called flow under standard state;
(2) Plant can be stably & reliably operate during 75 -100% of processing feed air;
