PSA
Nitrogen Gas Plant
Our Nitrogen Plant operating on PSA technology, consists of twin tower system filled with special grade of carbon molecular sieves (C.M.S.) at a time, one tower keeps in production cycle and other in regeneration cycle. When compressed air passed through C.M.S. bed, the molecules of oxygen, moisture & other unwanted gases are adsorbed on surface of C.M.S. and the nitrogen which is not adsorbed by C.M.S comes out of adsorption tower and is collected in a surge vessel.
PSA Nitrogen Gas Plant is provided, if the requirement at the discharge is at higher pressure. Normally our PSA system can provide pressure at discharge to about 6 kg/cm2g but it can be increase up to higher pressure of 150 kg/cm2g based on client's requirement. for this we need additional booster, suction pot and finned cooler after the surge vessel so as to enhanced the pressure up to higher pressure before storage tank. Rest of the principle is same as ms model.

Purity of Nitrogen
It is most economical to produce 98% pure N2 from PSA Plants. For applications which permit upto 0.5% Oxygen impurity, 99.5% pure N2 is generated by PSA Plants only. For Applications requiring better purity, 99% pure N2 is produced by PSA Plant followed by a Deox Catalytic Purification Unit, so that oxygen in the product nitrogen gas is brought down to level of 3 PPM.
Applications
These PSA type nitrogen generators being manufactured by us will be ideal for the following applications :
1. For bright annealing, hardening, tempering and other heat treatment applicaton in metallurgical industries.
2. For providing inert atmosphere in Breweries, Synthetic Fibre and Electronic Industries.
3. For Nitrogeneous packing in Food Industries.
4. For inertization to fight fires in collieries, cement plants etc.
5. To avoid the possibilities of any explosion in hazardous areas of chemical and Petrochemical Industries.
"MS" Model:
Our Nitrogen Plant/Generator operating on PSA technology, consists of twin tower system filled with special grade of carbon molecular sieves (C.M.S.) at a time, one tower keeps in production cycle and other in regeneration cycle. When compressed air passed through C.M.S. bed, the molecules of oxygen, moisture & other unwanted gases are adsorbed on surface of C.M.S. And the nitrogen which is not adsorbed by C.M.S comes out of adsorption tower and is collected in a surge vessel.
For continuous generation of nitrogen, two adsorption towers are provided which are interconnected with auto change over valves controlled by a sequence programmer.
When one tower saturates with oxygen the process automatically changes over to another tower and thus the nitrogen production is continuous. This model is the simplest to produce nitrogen of a purity in range from 95% to 99% purity. However, if carbon molecular sieves quantity is increased, even 99.999% purity nitrogen can be produced from this model. But running cost would be higher in case of higher purity.
It turns classified into two categories : 1.MS-L
2.MS-H
3.MS-L GAS COMPOSITION
| Flow Rate | 1-1000 Nm3 / hr |

| Oxygen | 10 ppm- 500 ppm |
| Hydrogen | Nil |
| Dew Point | (-)60oC to (-)80oC |
APPLICATIONS : As Inert gas in Chemical, Food Pharmaceutical Industries, Heat Treatment Furnaces, Electronic, Synthetic Fiber, Industries.
Deoxo Model
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 :
| Flow Rate | 1-1000 Nm3 / hr |
| Nitrogen | 99.9999% |
| Oxygen | 1 to 3 ppm(max) |
| Hydrogen | 0.5% or more |
| Dew Point | (-)40oC to (-)80oC |
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 :
| Flow Rate | 1-500 Nm3 / hr |
| Nitrogen | 99.9999% |
| Oxygen | 1 ppm (max) |
| Hydrogen | Nil |
| Dew Point | (-)40oC to (-)80oC |
Nitrogen Plant With Booster Model
Such kind of Nitrogen Plant with booster is provided, if the requirement at the discharge is at higher pressure. Normally our PSA system can provide pressure at discharge to about 6 kg/cm2g but it can be increase up to higher pressure of 10-150 kg/cm2g based on client's requirement. for this we need additional booster, suction pot and finned cooler after the surge vessel so as to enhanced the pressure up to higher pressure before storage tank. Rest of the principle is same as ms model.
