Brief Tech Index

1.) Nitrogen flow: 1-3000Nm3/h.
2.) Nitrogen purity: 97-99.9995%.
3.) Nitrogen pressure: 0.05-1.0 Mpa.
4.) Dew point: from -60 to -45 degree celsius.


Brief Principles

When the process adopts lifting air, oxygen and nitrogen have different diffusion rate and adsorptive capacity to separate oxygen from nitrogen on carbon molecular sieve(CMS). When air is compressed to 0.8MPa, air source enters in pressure-swing adsorption tower for separation after being purified through dry and oil-water separation process (filter). Oxygen molecules are diffused and adsorbed in carbon molecular sieve under pressure. Non-adsorbed nitrogen is discharged from outlet of adsorption tower. Oxygen is desorbed, discharged and purged in adsorption tower under depressurization. Moreover, adsorbent can be recycled.Paige brand.
