NITROGEN GAS PLANTS

Nitrogen Gas Plants

A PSA Nitrogen generation plant, utilizing the Pressure Swing Adsorption (PSA) process, comprises two adsorbers filled with carbon molecular sieves designed to selectively absorb oxygen from compressed air (CMS). In this process, compressed and purified air flows through the adsorbers. The carbon molecular sieves exhibit a preference for moisture adsorption, primarily capturing oxygen, allowing nitrogen-enriched gas to exit the absorber. Oxygen concentration can be tailored to meet specific requirements.

While one adsorber undergoes adsorption, the second adsorber undergoes complete regeneration through depressurization to ambient pressure. The oxygen-enriched off gas is vented during this regeneration phase. The system seamlessly switches to the second adsorber after approximately one minute of adsorption in the first adsorber, ensuring a continuous production of nitrogen.

APPLICATIONS

Our PSA Nitrogen Gas Generators Are Widely Used Across Many Industries Including:

 
 

Tyre filling (Automotive, Aircrafts, Dumpers, Mine Trucks)

Inflating rubber tires with nitrogen significantly extends tire lifespan by reducing oxidation and minimizing leakage, resulting in more stable pressure maintenance.

Fuel Tank Inerting (Petrochemical Complexes, Chemical Factories, Aircrafts)

The presence of air in fuel tank headspace can lead to the formation of a flammable mixture, and the flammability risk can be mitigated by purging and filling fuel tanks with nitrogen.

Autoclaves and Furnaces

Utilizing nitrogen in autoclaves and furnaces can lower the risk of flammability and combustion.

Blanketing for many industries (adhesives, pesticides, agro, pharmaceuticals)

Nitrogen gas is ideal for applications demanding minimal oxygen presence or an inert atmosphere.

Fire prevention (coal mines, mines)

The presence of air in fuel tank headspace can lead to the formation of a flammable mixture, and the flammability risk can be mitigated by purging and filling fuel tanks with nitrogen.

Oil & Gas and Petrochemicals (Pigging, Blanketing, Headspace filling, Pipeline drying)

The safe handling of volatile chemicals and petrochemicals necessitates the presence of nitrogen to ensure the secure management of process gases or liquids throughout different stages of handling.

Laboratories (LCMS, Turbo Vap, GC, GCMS)

Large laboratories with a centralized gas supply system experience continuous gas availability through the use of on-site generators for nitrogen and hydrogen.

Offshore Platforms & FPSOs

Nitrogen is indispensable for fire prevention when dealing with highly flammable crudes and volatile gases due to their handling requirements.

Oil cargo ships and oil tankers

The storage and transportation of oil and crude substances entail risks, necessitating the use of nitrogen to establish a fire-safe environment.
