O2 Recovery

Oxygen Concentration (Combustion Air, Medical Devices)

By supplying atmospheric air (oxygen concentration 21% and carbon dioxide concentration 450-500 ppm) to the NAGASEP module and depressurising the transmission side, the transmitted air is enriched to an oxygen concentration of 30% and carbon dioxide concentration of 1600-2000 ppm.The concentrated oxygen can be used for various applications, including:
  1. Boilers and other combustion applications
    1. Improved Combustion Efficiency
      • As nitrogen is removed, the amount of exhaust gas (nitrogen oxides) can be reduced accordingly.The reduction in exhaust gas emissions is as much as 40% when combustion is carried out with 30% oxygen-enriched air.
    2. Reduced exhaust gas emissions
      • As nitrogen is removed, the amount of exhaust gas (nitrogen oxides) can be reduced accordingly.
    3. Fuel cost saving
      • The higher the exhaust gas temperature, the higher the fuel cost saving. In this case, too, a good fuel saving effect can be achieved in the oxygen concentration range of 22% to 30%, making oxygen-enriched membranes suitable for this application field. The reduction in exhaust gas emissions is as much as 40% when combustion is carried out with 30% oxygen-enriched air.
  2. Oxygen Therapy
Normal, healthy people usually breathe unconsciously without feeling a particular need for air (oxygen concentration: 21%). However, it can also be used as home oxygen therapy to inhale oxygen at home as an assistive device for people who have respiratory illnesses or cannot take in enough oxygen in the atmosphere. It can also be used as a refreshing application for healthy people, where inhaling oxygen can help reduce fatigue and promote recovery from post-exercise exhaustion.
