2-200Nm3/h PSA Medical Oxygen Gas Plant with Cylinder Filling System

BangWin PSA oxygen generators utilize the well-known and mature Pressure Swing Adsorption technology. Atmospheric air comprises of 20-21% oxygen and the PSA process utilizes Zeolite molecular sieves to extract this Oxygen from air. Oxygen at 95% is delivered, while the nitrogen adsorbed by the molecular sieves is vented back into air through the exhaust line.

PSA Oxygen Plant process consists of 2 vessels filled with Molecular Sieves and Activated Alumina. Clean compressed air at 30°C temperature is passed through one vessel and oxygen comes out as product gas. The exhaust gas (Nitrogen) is discharged back into atmosphere. Upon saturation of the molecular sieve bed, the process switches Oxygen generation to the other bed by automatic valves, while allowing the saturated bed to undergo regeneration by depressurization and purging to atmospheric pressure. Thus 2-vessels keep cycling alternately in Oxygen production and regeneration ensuring Oxygen gas is continuously available to your process.

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 Oxygen with precisely the right purity.
