Home » Our Products » Nitrogen Plants
We design, develop and manufacture a stellar range of nitrogen plants. Designed to be compact and sturdy, these nitrogen plants are highly efficient and deliver high levels of performance at all times. The nitrogen plants require low levels of maintenance and can be custom developed as per the needs and specifications of our customers.
Nitrogen Generators (P.S.A. Based)
We design and manufacture a superior range of nitrogen generators with proprietary techniques that provide high efficiency of gas separation. These generators provide a high degree of control of nitrogen gas supply at minimal levels of maintenance. We have the capability to design and develop nitrogen generators as per the requirements of our customers.
How it works?
The nitrogen generator produces nitrogen gas from atmospheric air using molecular sieves separation technique. It uses a carbon molecular sieve which has ability to preferentially remove oxygen from air. Our proprietary technique gets higher efficiency of gas separation.
Nitrogen generator consists of two beds filled with carbon molecular sieves. When compressed air is passed, Nitrogen comes out as product gas from one bed while other bed is simultaneously regenerated by depressurization to atmospheric pressure. This process of gas separation is called "Pressure Swing Adsorption" (PSA).
From nitrogen generator gas of purities from 99% to 99.9999% can be produced. simple psa unit produces raw nitrogen of 99% purity. By adding purification unit to PSA unit, high purity nitrogen can be produced.
Nitrogen Generators are tailor-made equipment and are manufactured as per customer's requirements. However, standard units are available in the capacity of 1, 2, 5, 10, 25, 50, 75, 100, 150, 200, 300 NM3/hr. The Gas Generators can be manufactured in any desired capacity.
Standard Nitrogen Generator produces nitrogen at 5.5 kg/cm2g pressure. This pressure comes automatically as feed air pressure to the PSA unit is around 7 kg/cm2g. However, by increasing feed air pressure to 10kg/cm2g, Nitrogen can be produced even at 8.5 kg/cm2g. But, at high pressure operation, depressurisation losses during regeneration are high, which results in high operation cost.
It is most economical to run nitrogen generators at 7 kg/cm2g pressure and produce nitrogen at 5.5 kg/cm2g pressure. If nitrogen is needed at higher pressure, we can provide a nitrogen booster compressor after the gas generator. By this addition, it is possible to compress nitrogen gas to any high pressure.

Nitrogen Membrane System
How it Works?
Membrane nitrogen generators are built and supplied supplied by creative as skid, shop assembled units and include all equipment and instrument for generation of nitrogen gas of specified flow and purity. Higher the nitrogen purity level, lower is the nitrogen gas quantity and so operating cost increase membrane separator modules are imported from world leading manufacturer.
Nitrogen generator consists of two beds filled with carbon molecular sieves. When compressed air is passed, Nitrogen comes out as product gas from one bed while other bed is simultaneously regenerated by depressurization to atmospheric pressure. This process of gas separation is called "pressure swing adsorption" (PSA).

Membrane Nitrogen Separation Flow System
Membrane Nitrogen System
Compressed air is provided from dedicated air compressor to separate nitrogen from air by using membrane technology. A feed air cleaning system is provided ahead of the membrane separator to provide clean air, free from oil, water droplets and solid particles. The clean air will allow for high efficiency nitrogen production and ensure long life of the membranes.
