Nitrogen Generator

Nitrogen is an inert gas which is user friendly & ample in atmosphere.

Nitrogen gas is abundantly available in atmosphere; but to make it process worthy, we have to separate oxygen and minor part of inert gases from the air.

We have a PSA (Pressure Swing Adsorption) separation system to achieve all most pure Nitrogen through series of filtration process. We use dry compressed air as input and process it under close controls through imported special molecular sieves to achieve higher purity of N2 gas range from 98% to 99.999% (depending on usage of application)

We manufacture Nitrogen Gas Generator Plant, Nitrogen tyre inflator both industrial and laboratory models ranging from 1 m3/hr to 500m3/hr with 98 to 99.999 % purity.

Nitrogen is an important input for a wide variety of industries - pharmaceutical, chemical, food & beverage, metallurgical - to name a few. It is used for inert atmosphere, sparing, filling, transfer, and many other applications.

Parameters :
kindly specify following parameters to design the right unit

1.Volume of nitrogen reqd in m3/Hr. 2. Purity of Nitrogen Gas required in % or ppm 3. Pressure of N2 gas @ use point in Kg/cm2. or in bar. 4. Application in brief to justify purity actually needed. 5. Use pattern ( Constant / intermittent / pick for certain time ) 6. Usage time per day ( in Hours )

Features :

• Economical (Rs.6 to 8 per M3; compare to Rs.18 to Rs.20/M3)
• Gives constant purity
• Eliminates transport & supply dependency.

We also undertake reconditioning of any make of N2 plant.



How N2 gas Plant works?
TThe pure Compressed air is input of the N2 plant. It works on pressure swing Adsorption cycle. Hence called PSA Nitrogen Generator . The System has two Absorbers containing carbon molecular sieves (CMS) which separates out the oxygen and allows the nitrogen to pass through.

The nitrogen is collected in a Surge Vessel. Simultaneously, the other tower is rid of the oxygen (adsorbed in the previous cycle) by depressurization and back flushing of pure nitrogen from the Surge Vessel, to make it ready for the next adsorption cycle.

Prior to change-over, the exhaust & outlet valves are closed so that the pressure in both towers are equalized. Nitrogen is drawn from the Surge Vessel at a measured rate thru the flow (Rota) meter. An Oxygen Analyzer (OA) can be used to measure oxygen content of the nitrogen being delivered to the User devices.

Features&Advantages of Nitrogen Generator

PSA Nitrogen Generator

• Installation of PSA Nitrogen Gas Generator eliminates the hassles & hazards associated with use of Gas cylinders.
• The Nitrogen Generator gives a consistent purity of Nitrogen as compared to uncertain Nitrogen quality from Gas cylinders.
• Gas from Nitrogen Generator is very dry, thereby eliminating any problems due to presence of moistures.
• Gas of desired purity is obtained with a short time from start-up.
• The Gas Generator is fully automatic and does not require much attention. It has built-in safety features audio-visual alarm and / or automatic shut-down whenever system fault occurs.
• The cost of Nitrogen works out to around Rs. 6/50 per M3 which includes cost of power (at Rs. 4/50 per KWH) interest on capital, maintenance & adsorbent replacement costs.
• Overall cost of around Rs. 6/50 per M3 compares very with Rs. 15/-to 20/- per M3 for commercial nitrogen of uncertain quality in cylinders.

We also do revamping / repairing of any make of n2 / o2 gas Plant

Comparison of Gas Cylinder v/s Gas Generator with “Comparison of N2 Gas Cylinder v/s N2 Gas Generator

Description	N2 Gas Cylinders	N2 Gas Generators
Safety	Hazardous & sudden leakage can result into accident in the laboratory area because of high cylinder pressure of 150 bar	No cylinder & regulator and at all also avoid the risk and inconvenience associated with cylinder gas since generator operate on low pressure.Exm.4-6 bar
Economical	Price of cylinder is high as compare to generator , since lot of cost involvement towards rent, transport, handling , labor charges , down time, maintenance of cylinder and regulator ,sudden leakage etc.	Price is less compare to cylinder and imported generator + no custom + no excise duty.1time investment which can be recovered in few months.
Costing	Cost of cylinder is approximate Rs. 150/ M3 including miscellaneous expenses.	Cost of gas produced from gas generator Rs.12/m3 including power cost and maintenance.
Availability	Interruption in analysis since frequent replacement of gas cylinder and sometimes nonavailability of high purity gas cylinder and transport problem.	As there is no cylinder change it saves time and also it supplies gas round the clock 365 days pure and high quality gas supply.
Purity	Chance of impure gas means purity not constant in all supplies of cylinder	It always supply the gas of UHP grade and constant purity
Storage area	Lots of space require for storing cylinders	Less space require , as the generator can be stalled on the table on the floor on the laboratory.
	Imported Generator	Indian Generator
Service	Service may not be fast as the parts are not easily available and down time machine may me more.	Service is very fast and parts are easily available since it is indigenous
Programming Facility	Generator is avoid to run initially 1-2 to get pure gas constant flow.	It has programming facilities,so no wastage of time an get always high purity gas
Parts	Parts are not easily available and costly also.	Parts are easily and are at reasonable rate

Industrial Piping is most neglected area due to casual approach and unnoticed power wastage, due to poor workman ship, improper sizing, illogical layout & poor material selection.

The havoc of leak can be judged by following effect of Leakage :-

Leak of : 1 drop/seconds = wastage of 8640 Liters/year
Leak of : 1mm Hole @ 6 bar Pressure = wastage of 3838 power units (KWH) /year

We introduce the Zero leak ‘FUSION’ plumbing solution. The German concept of PPR piping.

PPR means Polypropylene Random Co polymer.

Why coolers are required? :
Compressed air is very hot (About 160°C to 220°C Temperature) at ultimate outlet end. It need to be cooled by versatile shell & tube water cooled after cooler (Heat Exchanger) with water as a cooling media or by air cooled after cooler with forced fan cooling air as cooling media. The temperature comes down nearly to room temperature from high degrees effectively.

Types

I. Water cooled after cooler ( Horizontal / Vertical ) A-1” Make state of art water cooled after coolers. This is the equipment which cool down the inlet, hot compressed air [ Approx. Above 160 Deg. C ] by using water as cooling media surrounding the copper tube bundle carrying Hot Compressed air. Hot Air is passing through special grade of copper tubes bundle which exchanges the temperature of hot air to the circulating water in the shell at ambient temperature( 40 Deg. C ). The cooled air with velocity spins and collides in the adjacent Moisture separator unit. Here the mist with pre cooled heavy water particles forms droplets and thus condensate collect at the bottom part of the Separator. It can be drained manually by operating ball valve or for most effective drain, Electronic timer type Automatic drain valve is best. A-1I. Air Cooled after cooler” Make State of art Air cooled after cooler. It is the equipment which cool down the inlet, hot compressed air by using forced cooling of back side powerful Centrifugal fan. Hot Air is passing through copper specially finned tube bundle which dissipates hot air using fresh pressurized air at ambient temperature( 40 Deg. C ). The cool air with great velocity apply force shower effectively to do active heat exchange in to the system and results in to reduction in temperature of compressed air from initial high degree to desired near by ambient temperature. AIR COOLED AFTER COOLER: A-1” Make State of art Air cooled after cooler. It is the equipment which cool down the inlet, hot compressed air by using forced cooling of back side powerful Centrifugal fan.
