How do Oxygen Generator work?

OXYSWING VPSA units are designed for the oxygen generation from ambient air.

Depending on customers’ focus and demands the VPSA systems are designed invest or energy optimized.

Purities of up to 94 vol.-% oxygen product quality can be achieved. Product gas pressures > 1,2 bar(abs) will be achieved by means of subsequent oxygen compression.

The vacuum pressure swing adsorption (VPSA) technology employs the basic principle of air separation at ambient temperatures by using zeolite (a material that adsorbs nitrogen to leave a rich stream of oxygen).

Individual plant concepts with respect to local situation (building available, etc.), admissible sound emission, integration in the production process can be offered.

For a detailed process description and process flowsheet please click here.

For the generation of oxygen by means of the pressure swing adsorption process (PSA, VSA, VPSA) mainly the following molecular sieves (zeolites)are used:
Calcium-zeolite A
Sodium-zeolite X
Calcium-zeolite X
Lithium-zeolite X

Because the adsorption process cannot separate all the argon. Therefore at 95% oxygen we have less than 0,15% nitrogen, the rest is mainly argon.

Additional/Optional features for oxygen generation plants:

Our plants are used worldwide. Especially for Russia, Belarus and Kazakhstan we are able to provide our OXYSWING plants with all necessary TR certificates and declarations for the import and operation in the Custom Union, in particular with a declaration according TR CU 010/2011 (MD), TR CU 004/2011 (LVD) and TR CU 020/2011 (EMC) for the entire oxygen plant. Certificates or declarations according TR CU 032/2013 for all pressure vessels are also part of our scope of supply.
