  • Nitrogen generator
  • This technology is recommended for high purity applications (>99.9%).

    PSA (Pressure Swing Adsorption) nitrogen generators are built using two activated charcoal CMS (Carbon Molecular Sieve) columns. CMS is a special type of activated charcoal whose pores, at high pressure, can absorb oxygen, carbon dioxide and water vapor while enabling nitrogen and other inert gases to pass through. By alternately increasing and decreasing the pressure within these columns, the nitrogen is separated from the other gases.

    Before entering the activated charcoal columns, the conventional compressed air must be dried and purified using the high-yield air pretreatment package included with the Absoger nitrogen generators.  While one of the columns produces nitrogen, the other regenerates the CMS through depressurization.  In this way, the system continuously provides a stable, highly pure nitrogen output.

    Technical characteristics

    • Produced nitrogen purity: from 95% to 99.9999%
    • Produced nitrogen output: 1 to 2000Nm3/h – a greater output is available upon request.
    • Nitrogen output pressure: 5 to 330 bar
    • Very low energy consumption
    • Good resistance to oil and dust
    • Long activated charcoal product life-span

    This technology is recommended for medium or low purity applications (<99.9%).  ABSOGER manufactures and certifies our own membranes.

    This technology is usually used on offshore FPSO or FLNG platforms. The membrane must be supplied with dry air. This air is filtered as it is passed through the hollow-fiber membrane. The nitrogen from the compressed air inside the membrane is separated using the material’s selective permeability properties. Water vapor and oxygen are safely rejected into the atmosphere while nitrogen is channeled back into the system.

     

    Technical characteristics

     

    • Produced nitrogen purity: from 95% to 99.5%
    • Produced nitrogen output: 1 to 2000Nm3/hour – a greater output is available upon request
    • Nitrogen output pressure: 5 to 330 bar
    • It is possible to change the membrane in the event of a defect without stopping the generator
    • A compact system: reduced size and weight

    All of our nitrogen generators can be delivered with or without an air treatment system. Depending on your needs and your initial installations, we will advise you on the best adapted solution.
