Industrial Oxygen Production from Ambient Air
The production principle is based on selective adsorption. Ambient air contains approximately 21% oxygen, while nitrogen makes up most of the remaining gas. After compression and treatment, the feed air enters adsorption vessels filled with molecular sieve material to generate continuous oxygen on site.
Ambient Air → Air Compression → Filtration & Drying → PSA Separation → Oxygen Buffer → Oxygen Supply
Why Generate Oxygen On Site?
For industrial users with regular oxygen demand, oxygen logistics can become a major part of operating costs. Cylinder delivery requires transportation, storage, handling, and regular replenishment. Bulk oxygen systems also require suitable storage infrastructure and supply arrangements. An industrial PSA oxygen plant changes the supply model by producing oxygen directly at the point of use.
The System Can Help Industrial Users
- Reduce dependence on external oxygen deliveries
- Maintain a continuous on-site oxygen source
- Match oxygen production with actual consumption
- Reduce cylinder handling and labor hazards
- Support 24/7 continuous long operating hours
- Simplify oxygen supply for remote industrial facilities
- Integrate oxygen production directly with existing processes
* The economic benefit depends on oxygen consumption, operating hours, local oxygen prices, transportation costs, and plant utilization.
Main Components of an Industrial PSA Oxygen Generator Plant
A complete industrial system normally consists of several interconnected subsystems rather than the PSA unit alone:
How an Industrial PSA Oxygen Plant Works
Ambient air enters through the intake system. Filtration equipment is matched to environmental conditions at site.
The compressor raises air pressure required for the PSA process, sized for output, purity, and altitude.
Removal of water, oil aerosols, and particles protects the molecular sieve and ensures stable, long-term operation.
Sieve preferentially adsorbs nitrogen while oxygen passes through. Vessels alternate between adsorption and regeneration.
Generated oxygen fills a buffer tank to maintain smooth pressure and compensate for downstream demand fluctuations.
Delivered at required flow, purity, and pressure. Optional downstream booster compressors can be added for high pressure.
Industrial Applications

Mathed to ozone generator specs.
Key Design Parameters
There is no single plant specification for every process. NEWTEK evaluates your complete demand before sizing:
- Oxygen Flow & Purity: Determines PSA capacity (up to 95% purity) and sieve volume
- Oxygen Pressure & Peak Demand: Determines compressor and buffer size
- Operating Hours & Space: Affects equipment utilization and layout
- Ambient Temp, Altitude & Humidity: Influences air density and feed air drying
Containerized Plant & Automated Control
For remote mining or temporary sites, the entire system can be pre-built inside a heavy-duty container incorporating compressor, PSA, buffer, control, piping, and ventilation.
PLC Automated Monitoring Includes:Feed-air & PSA vessel pressure, oxygen purity & flow, compressor status, valve timing, high/low pressure alarms, and safety shutdown.

Frequently Asked Questions (FAQ)
It is an industrial oxygen production system that uses Pressure Swing Adsorption technology to separate oxygen from compressed ambient air and provide oxygen directly at the production site.
Depending on the configuration, PSA oxygen systems can typically produce oxygen with purity up to approximately 95%. The appropriate purity should be selected according to the downstream process.
Yes. Multiple adsorption vessels operate through alternating adsorption and regeneration cycles, allowing continuous 24/7 oxygen production.
Yes. While PSA generates gas at moderate pressure, an oxygen booster compressor, high-pressure storage, and a cylinder filling manifold can be integrated downstream.
Yes, complete systems can be containerized for easy transport. Capacity is calculated from actual continuous & peak demand, operating hours, required purity, pressure, and site conditions.
