What are the desired specification for the nitrogen produced by a typical membrane type nitrogen generator?

What are the desired specification for the nitrogen produced by a typical membrane type nitrogen generator?

Nitrogen Separation Membranes can typically produce nitrogen at purities up to 99.5%, while PSA nitrogen generators can achieve purities up to 99.9995%.

How do you size a nitrogen generator?

Below are the steps for sizing a blanketing generator:

  1. Determine the gas flow rate due to the pump out.
  2. Find the gas flow rate due to atmospheric cooling.
  3. Add the requirements of 1 and 2 to get the flow rate capacity of the nitrogen generator needed.
  4. Determine the nitrogen purity level required for the application.

What is a nitrogen generator used for?

Nitrogen generators are used in hypoxic air fire prevention systems to produce air with a low oxygen content which will suppress a fire.

How does nitrogen generation plant work?

Essentially, a nitrogen generator works by separating nitrogen molecules from the oxygen molecules within compressed air. This can be done with a membrane nitrogen generator or a PSA (pressure swing adsorption) nitrogen generator connected to a compressor.

How much energy is in liquid nitrogen?

The energy density of liquid air and liquid nitrogen is 287.1 kJ/L and 255.8 kJ/L. For nitrogen, the energy storage systems should be closed systems.

How is nitrogen generated?

Nitrogen is produced commercially almost exclusively from air, most commonly by the fractional distillation of liquid air. In another approach, passing ammonia gas over a hot metallic oxide will result in the formation of free nitrogen, the free metal, and water.

Is nitrogen a good fuel?

Since, Nitrogen is an inert gas and is not a candidate as fuel. However, it can be used with Hydrogen to form Ammonia as energy carrier, since producing, storing and combustion of pure hydrogen has many limitations, which can be solved with Ammonia.

How is nitrogen explosive?

The explosiveness of nitrogen-containing compounds is driven by the huge release of energy that occurs when the nitrogen-nitrogen triple bonds form. A second factor makes nitrogen compounds explosive: the newly formed nitrogen molecules form a gas, which can expand very quickly and form a shock wave.

What are the dangers of liquid nitrogen?


  • Extreme Cold. The vapor of liquid nitrogen can rapidly freeze skin tissue and eye fluid, resulting in cold burns, frostbite, and permanent eye damage even by brief exposure.
  • Asphyxiation.
  • Oxygen Enrichment.
  • Pressure Buildup and Explosions.
  • Prudent Safety Practices.
  • Eye/face protection.
  • Skin protection.
