Nitrogen Generator

We manufacturer Nitrogen generator plant industrial and laboratory Models from 0.5 m3/hr to 200 m3/hr with 98 to 99.9 % purity.

Nitrogen gas is abundantly available in atmosphere; but to make it process worthy, we have to separate oxygen and minor part of innert 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 range from 98% to 99.999% (depending on usage of application)

Parameters : kindly specify following parameters to design the right unit

Purity of nitrogen in % Volume of nitrogen reqd in m3/Hr. Pressure of N2 @ use point in bar or in bar.

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.



GET NITROGEN FROM THIN AIR
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.

Nitrogen is abundantly available in atmospheric air, but to get pure nitrogen as required in the above applications, oxygen has to be separated out from the air. However, before reaching this stage, the air has to be rid of other impurities like dust, oil, moisture, etc, to ensure that air reaching the separation stage is pure. In most modem industries, dry compressed air is generally available and this is used as the feed air to the Pressure Swing Adsorption (PSA) Separation System (see sketch) to generate nitrogen.

In the PSA System, oxygen is separated from the compressed air by adsorption. 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 Rotameter. An Oxygen Analyzer (OA) can be used to measure oxygen content of the nitrogen being delivered to the User devices.

The PSA Nitrogen Gas Generator is a money-saving equipment which generates nitrogen at a substantially lower cost than that from cylinders. An additional benefit is that is eliminates the hassles & hazards associated with handling gas cylinders. We also undertake revamping of old Nitrogen Generators.

Features & Advantages

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 Nitrigen 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 reqire 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) intrest 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.

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 leackage 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 Plumbing is most neglected area due to casual approach and unnoticed power wastage, due to poor workman ship, improper sizing, insufficient 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 : 1 mm Hole @ 6 bar Pressure = wastage of 3838 kw/year

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

PPR means Polypropylene Random Co polymer.
