we will look how an on-site nitrogen generator works. Nitrogen is all around us, the atmosphere is made up of 78% nitrogen and 21% oxygen, therefore finding a way to generate nitrogen on-site would make perfect sense; as we adsorb oxygen and release back into environment. So why would you purchase bottled nitrogen when it is all around us.
In an oversimplified way of explaining how an on-site nitrogen generator works is to say that compressed air is passed through the generator. In the processes oxygen and other particles are removed from the compressed air and what is left is nitrogen. With an air compressor and a nitrogen generator there is an abundant supply of never-ending reliable nitrogen source which can be termed as a utility available continuously on-site to the door step What technologies can be used to generate nitrogen? Atlas Copco uses two different types of technologies for separating the nitrogen. First technology is called Membrane Technology, where the compressed air passes through a membrane fibres wall. As Oxygen molecules smaller than nitrogen they can escape the membrane filter passing only the nitrogen. The second type of technology use to create nitrogen is Pressure Swing Absorption (PSA), in this technology the compressed air (oxygen enriched) is passed through a vessel with a product called carbon molecular sieve (CMS); which adsorbed oxygen molecules and water content and allow nitrogen molecules pass through. Oxygen and water content released back to atmosphere. . Atlas Copco offer both Membrane and Pressure Swing Absorption technology based nitrogen generators.
