Oxygen Generator
Principles
N2 and O2 all have a quadrupole, for the reason that the quadrupole of N2 is bigger than the quadrupole of O2, the adsorption capacity by molecular sieve to N2 is stronger than O2.When the compressed air in certain pressure flow through adsorption bed formed by molecular sieve, the N2 gas is absorbed and O2 is obtained by separation.
The main part of O2 generator is two towers filled with molecular sieve ,when the compressed air get into adsorption tower, the N2 is absorbed by molecular sieve,O2 is produced from the export terminal .When one tower produces O2,another tower release the N2 by reducing the pressure to get the renewable desorption of carbon molecular sieve.Two towers alternate adsorption and regeneration to output O2 continuously.
Technical Features
1).Full Automation
All systems are designed for un-attended operation and automatic Oxygen demand adjustment.
2).Lower Space Requirement
The design and Instrument makes the plant size very compact,assembly on skids,prefabricated from factory.
3).Fast Start-up
Start-up time is only 5 minutes to get desired Oxygen purity.So these units can be switched ON&OFF as per Oxygen demand changes.
4).High Reliabiity
Very reliable for continuous and steady operation with constant Oxygen purity.Plant availability time is better than 99% always.
5).Molecular Sieves life
Expected Molecular sieves life is around 15-years i.e. whole life time of Oxygen plant.So no replacement costs.
6).Adjustable
By altering flow,you can deliver nitrogen with precisely the right purity.
