Being able to generate your own nitrogen implies that the user has complete control over their Nitrogen supply. It renders numerous benefits to companies that require N2 regularly.
With on-site Nitrogen Generators, you do not have to depend on third parties for the delivery, consequently eliminating the requirement for manpower that process, refill and replace the cylinders and delivery costs of these generators. One of the most common and trusted methods of generating nitrogen on-site is PSA Nitrogen Generators.
Working Principle of PSA Nitrogen Generators
The ambient air comprises of around 78% of Nitrogen. So, with just one tap, you can save up to 80 to 90% of your annual nitrogen costs.
A Pressure Swing Adsorption process uses Caron Molecular Sieves (CMS) to extract nitrogen from the air. PSA process consists of 2 vessels filled with Carbon Molecular Sieves and Activated Alumina. Clean compressed air is passed through one vessel, and pure nitrogen comes out as product gas.
The exhaust gas (Oxygen) is vented to the atmosphere. After a short duration of generation, upon saturation of the molecular sieve bed, the process switches nitrogen generation to the other bed by automatic valves while allowing the saturated bed to undergo regeneration by depressurization and purging to atmospheric pressure.
Thus 2-vessels keep cycling alternately in Nitrogen production and regeneration, ensuring high purity Nitrogen gas is continuously available to your process. As this process requires no chemicals, the annual consumable cost is extremely low. Sihope PSA Nitrogen Generators units are high-quality plants that last for more than 20 years with minimal maintenance costs and exceed 40,000 hours of service.
