FEIZHOU oxygen enrichment molecular sieve series are special used in PSA/VPSA system. They have good N2/O2 selectivity, good crush strength and low loss on attrition, which is cost-effective for concentrating oxygen from air. They are widely used in industrial/Medical oxygen concentrator in ozone production filed, Aquaculture field for fish farming,Waste water treatment field, medical oxygen market. etc. Their concentating purity up to 93%+-3%, having good reputation in market.
PRODUCTS DESCRIPTION
Lithium molecular sieve is a synthetic zeolite of lithium-type crystal structure, large Nitrogen adsorption capacity, highefficiency of oxygen/nitrogen separation. Below chart indicates lithium based molecular sieve((The temperature is 25℃)) It shows high N2/O2 separation under a very low pressure, which lowers the consumption of producing oxygen.The advantage of on the equilibrium adsorption capacity, It applies to various VPSA device for producing oxygen.

Hand & Storage Recommendation
Molecular Sieve should be handled to avoid generation of dusty conditions at the workplace. Storage in a dry warehouse is recommended. Open packages should be resealed to prevent contamination and adsorption of water or other gases and vapors. The material in bag-in-box should be used within 12 months,while bag-in-steel drum should be used within 24 months.

Regeneration
To achieve good operating performance and long life as much as possible, after a certain period of time use must be regenerated .After correct molecular sieve regeneration , make it get the low attenuation of mechanical properties and adsorption
There are two basic approaches:
Temperature variation .
Generally used in the preheating gas heating, purge molecular sieve to about 200℃, and stripping down the adsorbate .
Variable pressure .
Usually used in the gas phase adsorption process.Maintain a constant temperature adsorbent and by reducing pressure and backing purge inert gas , to remove the adsorbate.
