PSA oxygen generator

BROTIE PSA Nitrogen Generator (BR-A, B, C, D, E, F series with purity 95%, 99%, 99.5%, 99.9%, 99.99%, 99.999%) Principles: PSA nitrogen generator uses carbon molecular sieve as sorbent, produces nitrogen by making use of the PSA principle. Under certain pressure, carbon molecular sieve has different oxygen/nitrogen adsorption capacity, i.e. much more oxygen adsorption capacity than nitrogen adsorption capacity. PLC controls pneumatic valve on/off to realize two towers alternate adsorption and desorption as per pressure change, carries out oxygen/nitrogen separation and produces nitrogen with desired purity. BROTIE nitrogen generation system incorporates one air compressor, one refrigerant air dryer and filters, main nitrogen generator, air buffer tank and nitrogen buffer tank. With higher nitrogen pressure required, one BROTIE totally oil-free nitrogen compressor will be equipped after the nitrogen generator to increase the nitrogen pressure to required pressure. Compressed air is purified through the air dryer and filters to a certain level for main generator to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of work demand for air compressor. The generator produces nitrogen with PSA (pressure swing adsorption) technology, which is a time proven nitrogen generation method. Nitrogen with a desired purity is delivered to nitrogen buffer tank for smooth supply of product gas. Nitrogen in buffer tank is maintained at 6barg pressure. After BROTIE totally oil-free nitrogen compressor, the pressure will be compressed to required pressure.
