PSA N2 plant is a kind of equipment which employs the pressure swing adsorption principle to get nitrogen at normal temperature. It takes clean compressed air as raw material and CMS (carbon molecular sieve) as adsorbent. The diffusion rate in CMS and absorbing capacity on CMS’s surface of Oxygen and Nitrogen are different. Therefore, the PAS N2 plant can realize the process of pressurized adsorption and decompressed detachment by controlling sequencing valves’ on and off through programmable controller to separate Oxygen and Nitrogen and get purified Nitrogen that is needed.
Features
1. Fast starting speed, fast needed Nitrogen supply within 15 to 30 minutes.
2. Full automatic and unmanned operation.
3. High efficient filling through molecular sieve, longer service life.
4. Stable, adjustable pressure, purity and flow that can meet different requirements from customer.
5. Reasonable structure， advanced process and little energy consumption with safety and stability.
