Nitrogen Gas Generators

nitrogen generator equipment

Nitrogen generators allow companies to maintain a much cheaper source of a continuous supply of pure nitrogen, which has applications in industries ranging from food to pharmaceuticals. Air Energy’s nitrogen gas systems enable businesses to extract nitrogen from compressed air. Air Energy helps clients to choose the system that will meet their demand.

Nitrogen is the most abundant gas on earth – approximately 80% of our atmosphere. There are optional ways of separating the nitrogen for use in a wide spectrum of industry. Air Energy can offer you an independent cost-benefit analysis on the best nitrogen-generation solution for you.

The majority of applications that use nitrogen gas do not need the 10ppm, (99.999%) purity supplied by the traditional gas companies as bulk liquid or gas (cylinders). Providing customers with ultra-high purity nitrogen in all instances is an unnecessary waste of money and energy. Factors that influence selection of the best suited equipment include pressure, flow and purity as well as peak demand and average usage.

Membrane Nitrogen Recovery

The innovative membrane technology isolates nitrogen by channelling compressed air through bundles of hollow fibres, with walls permeable only to gases such as oxygen and carbon dioxide. This method generates 95 – 99.5 per cent pure nitrogen, with flows of up to 209.9 m³/hr.

Pressure Swing Nitrogen Generation

nitrogen3

Pressure swing Adsorption technology isolates nitrogen molecules from other molecules in compressed air. Oxygen, Carbon Dioxide other gases and water vapour are adsorbed. This results in virtually pure nitrogen at the outlet. These Nitrogen generators are a very cost effective source of nitrogen for various industries including

  • Food and Beverage
  • Metal Processing
  • Electronics
  • Pharmaceutical
  • Packaging
  • Marine and many others
  • Laborartory
  • Chemical
  • Laser cutting
  • Heat Treatment

These nitrogen gas systems only need a supply of compressed air and are highly efficient.

Pressure Swing Adsorption works in a similar way to Membrane Nitrogen Recovery, in that it isolates the gas by allowing molecules to permeate where nitrogen cannot.

This is possible through the use of Carbon Molecular Sieves (CMS), which are placed inside the entrances of two columns: one high-pressure adsorption column (8 bar) and one normal pressure desorption column (1 bar).

Compressed air passes through the first CMS, which has pores of only a little over 1 micron. This isolates much of the nitrogen from the desorption column, where only particles similar to oxygen can enter.

The process is completed in the adsorption column when the second CMS adsorbs the trace gases, allowing pure nitrogen to exit. The system will then switch both columns into regenerative mode, where it can expel the isolated particles before another batch of compressed air is introduced.
