| How it works? |
|
The nitrogen generator produces
nitrogen gas from atmospheric air using molecular sieves separation
technique. It uses carbon molecular sieves which has ability to
preferentially remove oxygen from air. Our proprietary technique get
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 depressurisation to atmospheric pressure. This
process of gas separation is called "Pressure Swing Adsorption"
(PSA). |
| Nitrogen Purity |
|
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. |
| Advantages |
- Automatic Start-up time is only 5-Minutes.
- Nitrogen gas supply always under your control.
- Self-contained skid mounted units for easy site
installation.
- Very low maintenance costs.
- Very high reliability to run un-attended plant.
- Carbon Molecular Sieves life is minimum 15-years and in
most cases it lasts the whole life time of Gas Generator.

| Nitrogen Capacity |
|
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.. |
| Nitrogen Pressure |
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. |

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.

molecular sieves. When compressed air is passed, Nitrogen comes out
as product gas from one bed while other bed is simultaneously

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. |
