PSA Nitrogen Generator

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.
