PSA (pressure swing adsorption, abbreviated as PSA) is a kind of advanced technology in air separation. As for the simple process and low investment, it is now the most popular solution in gas supplying.
The PSA system adapts Z.M.S (zeolite molecular sieves) for oxygen moleculars adsorption.
It affects by the different speading speed of different moleculars: in balanced condition, Z.M.S adsorbs same quantity moleculars of nitrogen and oxygen, but oxygen in moleculars spread much faster than nitrogen.
According to the feature of adsorption of carbon molecular sieve (ZMS), that the ZMS adsorb in pressurization and discharge in depressurization, we alternately compressed air into the two adsorption towers ( only one tower is also available) to separate the airs, high purity oxygen is continuously manufactured.
The purity and production efficiency can be adjusted per request: lowing the production capacity can increase the purity, while increase the production capacity decreases the purity.
ⅱFeatures of PSA system
1, Full set of equipment can run in time of request or have a sudden stop. Short starting time with high reliability.
2, Easy maintenance, less spare parts
3, Very simple operation, well-equipped monitors help to good running in state of neglect.
4, Advanced PLC control and data acquisition system, a data interface is kept for RMON
5, Scientific designation in structures, special gas diffusion unit, avoiding the high-speed impact by air flow and CMS being broken
6, Using the automatic internal balancing & clamping device, the unique sub-filling molecular sieve technology help to raise reliability in long term.
7, Oxygen emptying and interlock device ensure the quality level of oxygen.
8, Less occupation in land, easy installation, poor requirement in workshop, no request in foundation.
ⅲMolecular Sieves
Molecular sieves are the core components of PSA oxygen generation system. We adapt C.M.S ( carbonic molecular sieve) for oxygen generation. It adsorbs oxygen, carbonic dioxide and moistures at first, oxygen is separated then.
