Producing your company’s nitrogen in-house can save your company money, meanwhile reducing the cost of nitrogen consumption by removing the need for delivery costs, tank rental fees, etc. The return on investment can be covered in as little as 6 to 18 months. Generating your own nitrogen can provide a 75-90% cost savings!
The earth’s atmosphere is comprised of approximately 78% nitrogen and 21% oxygen. A PSA nitrogen generator removes the oxygen portion of the atmospheric makeup through a process called regenerative adsorption. A product called Carbon Molecular Sieve commonly referred to as CMS performs the adsorption portion of the process. Dual towers are the key component of the regenerative part of the process that allows the CMS to adsorb oxygen in one tower while the other tower is regenerating the CMS from previously adsorbed oxygen. When the current tower becomes saturated with oxygen the towers invert and the regenerated tower begins adsorbing oxygen while the other begins regeneration. This cyclic action continues allowing the GN2 to produce a steady stream of nitrogen gas. This process is commonly known as Pressure Swing Adsorption (PSA).
