On-board Oxygen/Nitrogen Generating Unit for naval applications

Oxygen/Nitrogen Generating Unit integrated into a harsh environment

Air Liquide is developing units for the production of oxygen and nitrogen in a marine environment, based on technologies of gas separation at ambient temperature. It meets on-board needs in gaseous or liquid oxygen as well as gaseous nitrogen, for example on aircraft carriers or frigate.

 

Benefits

  • Easy-to-use: no special technical skills are required
  • Customized for harsh marine environment

 

Applications

Gaseous oxygen on-board

  • To fill emergency egress devices and back-up cylinders for aircraft or helicopter
  • For medical use, compliant with STANAG standards

Liquid oxygen on-board

  • To fill oxygen converters for aircraft

Gaseous nitrogen on-board

  • To inert the jet fuel tank
  • To purge hoses, pipe and external underwing fuel tanks
  • To inflate tires, to fill landing struts and hydraulic system
  • To cool infrared cameras and cells (optronics).

 

Main technical characteristics

The units are tailored on demand. They are supplied by low pressure air production modules.

Oxygen generation 

  • 99.5% oxygen purity 
  • Normal operation: 50 to 100 Nm3/day (capacity example)
  • Oxygen distribution in gaseous form up to 250 bar or liquid 

Nitrogen generation 

  • Production: 100 to 200 Nm3/day (capacity example)
  • Nitrogen distribution in gaseous form up to 250 bar

Gas quality is continuously monitored in respect of each unit so that the purity of the gasses generated can be verified.
