Description
PSA nitrogen generator is an automatic equipment which separate
nitrogen from air. According
to the performance of molecular sieve, its adsorption when pressure
risen and desorption when pressure loose. Molecular sieve’s surface
and inner surface and interior are filled with micro pores. Oxygen
molecule has a faster diffusion rate of molecular sieve and
nitrogen molecules has a slower diffusion rate. Nitrogen molecules
are enriched in the end from the absorption tower.
Nitrogen generator is constructed according to the principle of
operation pressure swing adsorption and it compressed by two
absorption towers filled up with molecular sieve. The two
absorption towers are crossed by compressed air (previously
purified oil, water,dust, etc) . While one of the absorption tower
produce nitrogen, the other one release oxygen gas to atmosphere.
The process comes in cycle way. The generator is controlled by PLC.
Nitrogen is the best and the richest protective gas in the air. Gaseous nitrogen is a colorless, odorless, inert, tasteless,non-corrosive, and nonflammable gas. Nitrogen is nontoxic but can act as asphyxiating by displacing the necessary amount of oxygen in the air to sustain life (minimum 19% oxygen is required for life support). Every kind of gas the air average contains is: N2: 78.084%, O2: 20.9476%, Ar: 0.9364%, CO2: 0.0314%. Others like H2, CH4, N2O, O3, SO2, NO2 are scant. Nitrogen’s molecular weight is 28. Boiling point is –195.8 deg. C, Condensation is –210 deg. C.
