Nitrogen Gas Generation

Supplier: Air Energy

Our solutions for Pressure Swing Nitrogen Generation and Membrane Nitrogen Recovery include independent cost-benefit analysis for your ideal Nitrogen solution.


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. 

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 uses a bundle of hollow fibres that allows Nitrogen to pass through, and other gases such Oxygen, Carbon Dioxide and water vapour to permeate out. Compressed air enters at one end and Nitrogen exits at the outlet. Membrane technology generates nitrogen with a purity between 95 -99.5% with flows up to 209.9 m³/hr.

  • Requires just a supply of dry compressed air
  • Easy to install
  • No specialist commissioning
  • Includes Pre Filter, Pressure gauges, flow meter for constant monitoring
  • Low operating expense
  • Saves labour, time refills delivery charges associated with bottled supplies
  • Oxygen content can adjusted from 5% to 0.5% 

Ideal for:

  • Fire prevention
  • Tyre inflation
  • Oil & gas applications
  • Marine
  • Packaging
  • Many other applications

Pressure Swing Nitrogen Generation

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 generators only need a supply of compressed air and are highly efficient.

The pressure swing adsorption (PSA) principle to produce a continuous stream of nitrogen gas from compressed air. Twin columns are filled with carbon molecular sieve (CMS). Clean dry compressed air enters the bottom of the ‘online’ column and flows up through the CMS. Oxygen and other trace gases are preferentially adsorbed by the CMS, allowing nitrogen to pass through. After a pre-set time the on-line column automatically switches to regenerative mode, venting contaminants from the CMS. Carbon molecular sieve differs from ordinary activated carbons as it has a much narrower range of pore openings. This allows small molecules such as oxygen to penetrate the pores and separate from nitrogen molecules which are too large to enter the CMS. The larger nitrogen molecules by-pass the CMS and emerge as the final product gas.
