Discuss your requirementsTHE APPLICATION
Oxygen from air.
Supply at the source.
Vacuum pressure swing adsorption separates oxygen from air using molecular sieve adsorbents. A complete package connects air supply, adsorption, vacuum regeneration and oxygen delivery.
VPSA uses low-pressure adsorption and vacuum regeneration. Multiple beds work in alternating cycles to sustain oxygen production.
THE PROCESS
A coordinated cycle.
Production and regeneration work together to sustain the oxygen supply.
01
Air supply
Filtered ambient air is supplied to the adsorption system.
02
Selective adsorption
Molecular sieves preferentially adsorb nitrogen, enriching the oxygen stream.
03
Vacuum regeneration
A vacuum system regenerates the adsorbent while the beds alternate duties.
04
Buffer & delivery
Oxygen is buffered and delivered at the pressure required by the downstream process.

TECHNOLOGY & SCOPE
Engineered as a system.
Each package needs to fit the process, site conditions and operating requirements.
01
Adsorption equipment
Axial or radial bed arrangements are selected to suit flow, pressure drop and the project layout.
02
Cycle valves & automation
Frequent-switching valves and coordinated controls manage adsorption, regeneration and oxygen delivery.
03
Plant integration
Blowers, vacuum equipment, piping, cooling, noise control and power interfaces are considered as one package.
04
Downstream oxygen supply
Required product purity, flow and battery-limit pressure define the supply scope, including oxygen boosting where specified.

BEFORE YOU SPECIFY
Common questions.
What oxygen purity can be specified?
VPSA commonly supplies oxygen in the 80–93% range. Final purity, flow and delivery pressure are defined together for the proposed system.
Is delivery pressure the same as adsorption pressure?
No. Adsorption pressure is an internal process condition. Oxygen delivery pressure is a separate requirement and may call for a downstream booster.
How should energy consumption be compared?
Use the same oxygen purity, delivery pressure, reference conditions and equipment boundary. Clarify whether the figure is per unit of product oxygen or pure oxygen equivalent.
