PSA Nitrogen Generators

Do you really need 99.99% purity nitrogen ? In many instances, the answer is simply no. In which case, you may be spending more than is necessary on your nitrogen supply. However, if the answer is yes, then Glastons’s range of PSA Nitrogen Generators can ultimately make a positive impact on your bottom line. The versatility of PSA Nitrogen Generators has seen them gain popularity in numerous industries, including plastic moulding, chemical manufacturing, food and beverage production, and packing processes. The key benefit of having an industrial PSA Nitrogen Generator onsite is cost, with up to 40% savings to be made compared to purchasing nitrogen cylinders.

What is a PSA nitrogen generator?

Pressure Swing Adsorption, or PSA, is a technology used to separate some gas species from a mixture of gases under pressure. Pressure swing adsorption nitrogen generation is based on the theory that gases subjected to high pressures tend to be attracted to solid surfaces, or adsorbed. This process can be used to separate gases in a mixture because different gases are attracted to different solid surfaces to varying degrees

With a PSA Nitrogen Generator, the air is separated by compression on a bed from carbon molecular sieve, also known as a CMS, which preferentially adsorbs the oxygen. At the same time, in a second drum of the CMS, the pressure is lowered; this leading to adsorbed oxygen which is exhausted. This bed of CMS, now denuded of oxygen, is again ready for a further compression cycle of adsorption.

Carbon molecular sieve has a much narrower range of pore openings than ordinary activated carbons. This allows small molecules, such as oxygen, to penetrate the pores and be separated from nitrogen molecules which are too large to enter the CMS. The larger molecules of nitrogen, therefore, bypass the CMS and emerge as the product gas within the nitrogen PSA unit.

At Glaston, our team of highly skilled and experienced engineers have considerable expertise in the design, supply, and maintenance of PSA Nitrogen Generators in the UK.

Pressure Swing Adsorption (PSA) is cost-effective for onsite nitrogen generation of purities higher than 99%. With the Glaston range of PSA Nitrogen Generators, purities as high as 99.999% are achievable and, in high energy cost regions for lower purities, down to 95%.

In other words, PSA nitrogen generators (also known as PSA N2 Generators) offer flexible and affordable nitrogen supplies. At Glaston, we can offer a full turnkey solution, including design, supply and maintenance.
