On-site N2/02 generation offers cost-savings

16 October 2016

A host of new functions, including O2 analysers and energy control, have been included in the latest N2 and O2 high purity, low energy nitrogen and oxygen generators from Hi-line Industries. 

Producing nitrogen and oxygen on site, on demand, can offer cost savings when compared to purchasing bottled or bulk tanks of the gasses. 

The technology employed at Hi-line for N2/O2 generation is based on simple PSA (Pressure Swing Adsorption) procedures which sees twin-tower CMS (carbon molecular sieve) beds adsorb and regenerate to remove either N2 or O2 depending on requirements. This allows users to generate nitrogen at the purity required for the application, such as 95% or 98% for example, offering a more cost-effective than buying-in UHP (Ultra High Purity) nitrogen at 99.99999%, which is normally sold as standard without any option for the customer.

Among the areas where the uptake of Hi-line’s N2/O2 generators has been particularly high is MAP (Modified Atmosphere Packaging), a technique used for prolonging the shelf life of fresh or minimally-processed foods such as meat, fish, cheese, fruits and vegetables. The mixture of gases in the package depends on the type of product, packaging materials and storage temperature.

One well-known food packaging company, for example, was spending in excess of £120,000 per annum on N2 for MAP, excluding delivery charges associated with a tanker arriving at the plant four times a week. Hi-line was able to supply a N2 generator skid for a one-off fee of £55,000. Now, the plant produces its own N2 for only the cost of air compressor energy.
