Vacuum Pressure Swing Adsorption oxygen equipment, referred to as VPSA oxygen production equipment. The mixed bed is formed by VPSA special molecular sieve(lithium-based molecular sieve) and the desiccant is used to selectively adsorb impurities such as nitrogen, carbon dioxide and water in the air, so that oxygen accumulates and collects at the end of the bed, and the molecular sieve bed with adsorption saturation state is desorbed under the condition of evacuation, so as to circulate the oxygen with high purity (90~95%)。
PSA VS VPSA
PSA oxygen production is separated by pressurized adsorption and atmospheric pressure desorption, and the VPSA oxygen concentrator desorbs the adsorption-saturated molecular sieve under vacuum conditions. VPSA is less energy-consuming, and more environmentally friendly than PSA.
VPSA Zeolite Molecular Sieve
Lithium molecular sieve, used for air separation to produce oxygen and oxygen-enriched air, suitable for small VPSA (vacuum pressure swing adsorption) devices. Lithium molecular sieve has the advantages of large nitrogen adsorption capacity, high nitrogen and oxygen separation efficiency, fast dynamic adsorption and desorption speed, good oxygen production purity and long service life.
