Nitrogen Molecules: Key Characteristics and Their Implications
Air is primarily composed of approximately 79% nitrogen gas, with oxygen making up the remaining 21%.
One notable trait that sets nitrogen gas apart from others is its slow movement, coupled with larger molecular size relative to other gases such as oxygen. This larger dimension facilitates the effective separation of nitrogen from oxygen through PSA technology.
Separation Process Utilizing a CMS Bed
PSA nitrogen generators function as filtration systems, effectively removing oxygen from the air. The resultant nitrogen gas can be utilized extensively across various industrial sectors including Modified Atmosphere Packaging (MAP) in food production, laser cutting, and tank blanketing of hazardous materials.
These generators are equipped with two pressure vessels containing carbon molecular sieve (CMS), a highly porous material that enables adsorption at a molecular level. In order to generate nitrogen, compressed air passes through a CMS-filled vessel, where the tiny oxygen molecules are adsorbed, allowing the nitrogen to exit from the opposite end of the vessel.
Transition Process to Nitrogen Buffer Tank
The nitrogen generated is subsequently directed to a separate buffer tank to build up pressure. This stored nitrogen gas can then be accessed for various applications as per requirement.
Achieving High Purity Nitrogen Delivery
Utilizing PSA technology, businesses can produce nitrogen gas with purities ranging from 95% to over 99.999%. The flexibility offered by PSA in selecting appropriate nitrogen purity for specific uses leads to more economical nitrogen production solutions.

Organizations dependent on nitrogen gas can significantly reduce production costs and minimize their environmental impact by opting for onsite PSA nitrogen generators. An investment in these generators usually sees a rapid return, typically between 6 to 18 months. Additionally, in-house nitrogen generation eliminates reliance on external suppliers, mitigating delivery delays and contributing to reduced carbon emissions.

Understanding OXYMAT On-Site Nitrogen Generators
OXYMAT's onsite nitrogen generators are founded on the widely recognized PSA (pressure swing adsorption) technology. Two pressurized vessels filled with molecular sieves facilitate continuous nitrogen production by separating nitrogen from other gases.
A typical OXYMAT nitrogen generator consists of two pressure vessels accommodating carbon molecular sieves (CMS). Dry compressed air is channelled through a valve into one vessel, building pressure to between 5 to 10 bar(g). During this process, unwanted gases, primarily oxygen, are adsorbed while nitrogen flows into the accumulation tank.
As pressure increases in one vessel, the other undergoes a pressure reduction, ensuring seamless nitrogen flow. Before the next adsorption or desorption phase, both vessels equalize in pressure. When the pressure drops in the first vessel and the CMS pellets are saturated, the residual waste is expelled via the exhaust system, while the second vessel accumulates excess pressure until equilibrium is restored between both vessels.
