psa principle :
nitrogen gas generator consists of two beds filled with carbon molecular sieves . When compressed air is passed , nitrogen comes out as a product gas from one bed while the other bed is simultaneously regenerated by depressurization to atmospheric pressure . This process of gas separation is called pressure swing adsorption(psa)

psa nitrogen gas generator produces nitrogen gas from atmospheric air by psa (pressure swing adsorption) technology. Psa technique is a simple & reliable process of separation of nitrogen from compressed atmospheric air by adsorption of oxygen over a bed of carbon molecular sieves (cms). Cms is an adsorbent having infinite number of small pores. The diameter of the bottle necks is in the same range as those of the molecules. Thus when cms is used in the psa process, an oxygen molecule, having a smaller diameter than a nitrogen molecule traps in to the pores. Therefore the nitrogen is recovered to a high degree while almost all the oxygen is adsorbed.

process:- the production of nitrogen gas from atmospheric air is based on pressure swing absorption (psa) principle by adsorption of oxygen gas using a special grade of imported carbon molecular sieves (cms). Atmospheric air is compressed by an air compressor to a pressure of 7.5 kg/cm2g and cooled to ambient temperature in a shell and tube type heat exchanger. The condensed moisture shall be drain out automatically from air receiver by automatic drain valve (adt). The compressed air at ambient temperature is passed through psa module packed with activated alumina and special grade of carbon molecular sieves. The production of nitrogen from air by psa technology is largely based on the kinetic separation. Oxygen that is smaller in size (kinetic diameter 3.46 a0) diffuses much faster than nitrogen (kinetic diameter 3.64 a0) and hence oxygen gets adsorbed in carbon molecular sieves and nitrogen is collected as the high-pressure product. The entire operation is fully automatic and controlled by a combination of sequence programmer and quick change over valves. Nitrogen gas of desired purity at 5.5 kg/cm2g pressure and having a dew point of (-) 40 degree celsius is produced by the psa unit, now flows to a surge vessel to balance the fluctuations in pressure and concentration. Now the gas can be stored in a storage tank at 5.5 kg/cm2g pressure from where it can be made available for process application. The storage tank can selected of any desired capacity as per peak hours demand for nitrogen gas or power interruptions. This system is fully automatic and need not any special operator for operation. Once it is started it generates nitrogen at constant flow rate and at constant pressure. Further the produced nitrogen gas can be boosted to high pressures by providing any reliable booster compressors up to desired pressure. We offer various models of nitrogen gas plant and selection is based on the purity required.

we are exporting psa nitrogen gas generators to various countries such as middle east , bangladesh , nepal , brazil, south america, africa , india & other countries. We have our after sales & service teams we are providing after sales & service to all over the world including india

nitrogen pressure:
standard nitrogen generator produces nitrogen at 5.5 kg /cm 2 g pressure. This pressure comes automatically as feed air pressure to the psa unit is around 7.5kg /cm2g. However , by increasing feed air pressure to 13 kg/cm2g. Nitrogen can be produced even at 10 kg / cm2g. But at high pressure operation , depressurization losses during regeneration are higher, which results in high operation costs.
it is most economical to run nitrogen generators at 7.5 kg/ cm2g pressure and produce nitrogen at 5.5 kg/cm2g pressure . However by increasing feed air pressure to 13 kg/cm2g. Nitrogen can be produced even at 10 kg / cm2g. If nitrogen is needed at higher pressure , we can provide a nitrogen
booster compressor after the gas generators .by this addition , it is possible to compress nitrogen gas to any desired high pressure.

we are exporting psa nitrogen gas generators to various countries such as middle east , bangladesh , nepal , brazil, south america, africa , india & other countries. We have our after sales & service teams we are providing after sales & service to all over the world including india

nitrogen pressure:
standard nitrogen generator produces nitrogen at 5.5 kg cm 2 g pressure. This pressure comes automatically as feed air pressure to the psa unit is around 7.5kg cm2g. However , by increasing feed air pressure to 13 kgcm2g. Nitrogen can be produced even at 10 kg cm2g. But at high pressure operation , depressurization losses during regeneration are higher, which results in high operation costs.
it is most economical to run nitrogen generators at 7.5 kg cm2g pressure and produce nitrogen at 5.5 kgcm2g pressure . However by increasing feed air pressure to 13 kgcm2g. Nitrogen can be produced even at 10 kg cm2g. If nitrogen is needed at higher pressure , we can provide a nitrogen
booster compressor after the gas generators .by this addition , it is possible to compress nitrogen gas to any desired high pressure.

advantages of psa nitrogen gas generators:
1. Self- contained skid mounted units for easy site installation.
2.very low maintenance costs.
3. Very high reliability to run un-attended for months & months.
4. Carbon molecular sieves life is minimum 10-12 years in normal working condition & in most cases it is whole life of the psa nitrogen gas generators.

skid mounted psa nitrogen gas generator systems consists of :
1.air compressors system with cooler.
2.air receiver cum moisture separator with automatic drain and high- level alarm.
3.air dryer refrigerated dryer to make air-sub -saturated
4.coarsed and fine filter for oil and solid removal
5. Ultra fine filters
6.twin tower psa unit
7. Surge vessel
8. N2 gas tanks
9. Booster pump if required for higher discharge pressure of nitrogen gas
10. Microprocessor control panel


we offer various models of nitrogen gas plant and selection is based on the purity required which are as follows :

ms model :

1. Ms-l
2. Ms-h

1. Ms-l (gas composition ) :
nitrogen 98-99 %
oxygen 0.1- 2 %
hydrogen nil
dew point (-)40c to (-)80c

applications : - as inert gas in chemical industries - food & pharmaceutical industries - for fire control in coal mines etc.

1.ms-h ( gas composition ) :

nitrogen 99.5 -99.999%
oxygen 10 ppm- 500ppm
hydrogen nil
dew point (-)60c to (-)80c

applications : - as inert gas in chemical - food pharmaceutical industries - heat treatment furnaces - electronic, synthetic fiber, industries.

deoxo model applications :
manufacturer and exporter of deoxo model. This model is commonly used in metallurgical industries for providing oxygen free nitrogen for heat treatment furnaces. Here, the oxygen is less than 1-ppm and but hydrogen is around 0.5 to 1% which is desirable as reducing constituent in most of heat treatment applications. ms models can also be converted into dx model by adding palladium deoxo reactor and gas drying unit. dx model is also applicable in chemical as well electronic industries.

gas composition :
nitrogen 99.9999%
oxygen 1 to 3ppm(max)
hydrogen 0.5% or more
dew point (-)40c to (-)80c

applications : - as inert gas in chemical & pharmaceutical industries. - in applications where oxygen impurity is not acceptable.
cu deoxo model :
cu deoxo model contains an extra nitrogen purification module based on copper deoxo catalyst. This model finds application in synthetic fiber, optical cables & electronic industries. Running cost of this unit is slightly higher because it produces very pure nitrogen gas i.e free from oxygen and hydrogen as well. It is applicable where hydrogen contents are detrimental to the process.

gas composition:
nitrogen 99.9999%
oxygen 1 ppm (max)
hydrogen nil
dew point (-)40c to (-)80c
applications: - as inert gas in electronic, synthetic fiber, - hitech industries where one needs ultra high purity.

industrial uses of nitrogen gas generators :
nitrogen generators are extensively used in the following industries:
chemical and petrochemicals industries for inertization, blanketing and purging requirements
ferrous and non-ferrous metallurgical industries for protective atmosphere during annealing, sintering and carburizing processes
pharmaceutical industries for inert atmosphere for reactions and for inert conveying
cement industries for fire prevention and fire fighting in coal mill silos
food packaging and processing industries for extending the shelf life of food products
glass industries for prevention of oxidation during manufacturing
transportation sector for nitrogen tire filling to extend tire life and increased safety
