Oxygen – PSA / VPSA / VSA / Membrane

Each Technology has unique attributes based on its operating principle. In general however the technologies can be grouped into low pressure or high pressure designs.

The PSA / VPSA / VSA technologies produce Oxygen at 93% purity +-2%. The Membrane technology produces Oxygen at 38% +-2%.

The VSA and VPSA technologies operate at very low pressures. This has significant advantages when it comes to power consumption for the blowers / compressors. The VSA and VPSA technologies are typically utilized where low pressures are all that is needed in the final application.

The VSA Technology is typically utilized in small to midsize requirements (oxygen requirements 5 tons per day or less) The VPSA product would typically be utilized in large oxygen requirements (5-200 tons per day) where energy consumption would become a major decision factor. Requirements greater than 200 tons per day would be best served by a cryogenic ASU.

Oxygen PSA Generator

Oxygen PSA Operating Principle

The PSA cycle is very similar to the VPSA. The main difference is that the PSA process operates at much higher pressures. The operating pressures of an Oxygen PSA are normally at 100 PSIG. This allows for the elimination of the Vacuum step necessary in both the VSA and VPSA process as during the vent cycle there is sufficient pressure differential to allow for the release of the Nitrogen from the Zeolite during the regeneration step of the process.

Oxygen VSA Generator

Oxygen VSA Operating Principle

Low Pressure Compressed Air is introduced into the absorber by means of a PD Blower. Air is passed through the Zeolite absorber bed. As the air passes through the Zeolite, Nitrogen is preferably absorbed from the air leaving the Oxygen to pass through. Once the bed becomes saturated with Nitrogen the air flow must be stopped and the pressure reduced. This accomplished by stopping the blower and reversing its direction. In this way the one blower can act as a compressed air feed source and a vacuum compressor. As the air pressure is reduced in the absorber the Nitrogen that was absorbed on the Zeolite is released and exhausted from the system. This cycle is continued over and over to product the quantity of oxygen required. To balance out any supply disruptions a buffer tank is utilized.

Typical Applications for VSA Technologies

  • Waste Water Treatment
  • Water Treatment
  • Aquaculture

Oxygen VPSA Generator

Oxygen VPSA Operating Principle

The VPSA cycle is very similar to the VSA except that the larger capacity requirements necessity of having two absorbers, one absorber producing oxygen and the other absorber being regenerated. This process requires a dedicated PD Blower to compress the air stream to support continuous operation and a dedicated Vacuum Brower to regenerate the absorber.

The VPSA process is more energy efficient due to the inherent continuous process and the primary reason this technology is selected for large scale high volume low pressure oxygen requirements.

VPSA Flows 5-100 tons per day

Oxygen Membrane Generator

Oxygen Membrane Operating Principle

The Oxygen Generators are the same product that is utilized in the GENERON’s patented Nitrogen membranes. Compressed air is passed through a bundle of hollow fibers. The Nitrogen is retained within the hollow fiber and the oxygen passes through the membrane wall. The oxygen is collected and vented from the membrane canister through the permeate port.

The Oxygen Membrane Generators are utilized in low volume point of use specialty type of applications.
