AIRRANE for Nitrogen
Schematic Diagram
Essential to a wide range of industrial processes and mechanical operations, securing a cost-efficient nitrogen gas is often an integral part of system engineering. However, conventional methods such as high-pressure cylinders, liquid tanks and bulk storage involve significant logistical issues and increase costs. Membrane separation presents an economic alternative which enables on-site nitrogen generation from the air we breathe -78% of which is nitrogen at sea level.
Key Applications
  • Fuel Tank inerting for Aircraft
    (OBIGGS)

  • Tire Inflation

  • Shipboard Inerting
    (FPSO, FLNG, LNG Carrier)

  • Fruits & Vegetable Storage

    • Chemical Processing

    • Preventing oxidation In manufacturing

    • LNG Tank Repair, Maintenance

    • Food packaging

    • Why Membrane for Nitrogen?
    • · Only requires compressed air to provide high-concentration nitrogen

      · Mobile unit to easily move installation place

      · No noise as separation can be carried out continuously

      · Compact size only requires minimal space

      · Can be installed either vertically or horizontally

      · Does not require additional power supply for nitrogen generator
