Nitrogen Generators & Plants

 PSA NITROGEN GENERATOS

We are a leading manufacturer / Exporter of Nitrogen generators. Such type of Nitrogen generators are most suitable when high purity is required ( more than 99%)

Technical Certitude :

01 Nitrogen Flow :-

Can be generate 1 – 3000 Nm3/hr with multiple PSA modules

02. Nitrogen Purity : -

Can be generate at any desired purity up to 99.9999% with different models

03 Nitrogen Pressure :-

In most application offered Nitrogen at 5 Kg/cm2 g pressure is suitable however it can be generate up to any desired pressure with Nitrogen gas boosters.

04 Dew Point :-

Generally our Nitrogen generator deliver dry gas up to (-) 40 to (-) 80°C. we offer online measuring instrument to measure dryness of gas.

HOW IT WORKS

•Atmospheric Air contains of approx. 78% Nitrogen & 20.9 % Oxygen.

•The PSA process utilized CMS to extract the nitrogen from atmospheric air.

•The PSA process comprise 2 – vessels filled with Carbon molecular sieves & Activated Alumina

•Once Oil free clean air passed through the vessel, pure nitrogen comes out as product gas.

•The exhaust ( adsorbed Oxygen) gas is vented to atmosphere. Once molecular sieves saturated, the process switch over to other tower by automatic valves. In mean time saturated bed to undergo regeneration by depressurization and purging to atmospheric pressure.

•Hence cyclic operation of 2 – vessels in nitrogen production & regeneration ensure continuous availability of Nitrogen gas to your process.

MEMBRANE NITROGEN GENERATORS :

We are a leading manufacturer / Exporter of Nitrogen generators. Such type of Nitrogen Generators most suitable for High flow and Low purity ( 95 - 98) %. Flow capacity of the plant can be increase by adding of membrane modules hence there is no upper limit of these generators.

Technical Certitude :

01 Nitrogen Flow :-

Can be generate 1 Nm3/hr to any desired flow with simple adding of modules.

02. Nitrogen Purity : -

Can be generate at purity ( 95 – 98)% directly which can be modulated by adjusting the flow rate.

03 Nitrogen Pressure :- Membrane Nitrogen Generators can generate Nitrogen directly at high pressure 15 Kg/cm2 g without any additional booster

04 Dew Point :-

Generally our Nitrogen generator deliver dry gas up to (-) 40 to (-) 80°C. we offer online measuring instrument to measure dryness of gas.

PROCESS OF NITROGEN GENERATION BY MEMBRANE

Membrane is constructed of polyimide hollow fiber membranes bundled into a cylindrical pressure container, with resin membrane elements fixed at both ends.

The compressed air fed into the interior of the polyimide hollow fiber membrane, and oxygen gas selectively permeates through the hollow fiber walls. Oxygen enriched gas is emitted from the permeable gas outlet, and nitrogen enriched gas out from the hollow fiber outlet.

APPLICATIONS :

Membrane nitrogen generators are widely used in several industries as

•Auotmotive & Aircraft industries and Mine Trucks for Tyre Filling

•In furnaces for inertization

•Blanketing purpose in chemical, pesticides and agro industries

•Inertization of fuel tanks in Petroleum industries

•Pigging & Blanketing purpose in Oil & Gas and petrochemical industries etc.

LIQUID NITROGEN GENERATORS :

JYH Big Engineering & Consultants brings the best liquid nitrogen generators with business tie up with Ulvac ( Japan). These are most suitable in hospitals for animals siemens preservation. Our offered capacities range from 7LPD TO 38 LPD.

HOW IT WORKS

Atmospheric air is sucked and compressed by an Air compressor at 7 bar pressure with high temperature. Afterwards it passed through an external refrigeration system to cool down the temperature. Further the cooled air passed through a moisture separator to remove the moisture. Now the dry and saturated air passed through a carbon molecular sieves bed where oxygen & Nitrogen get separated and remaining contents of air purged into atmosphere. Again this separated nitrogen pass through a Cryogenerator which works on stirling cycle which cools the gases nitrogen to a liquid state at 77 kelvin which is boiling point of Nitrogen.

Applications of Liquid Nitrogen

1. Serves as coolant for computers and vacuum pump systems

2. Cooling of superconductors

3. Storage of foods for food preservation

4. Cryopreservation of blood

5. Cryosurgery for removing dead cells from brain

6. Preservation of semen of animals

7. Working substance for liquid nitrogen power vehicle and much more.

Cryogenic Nitrogen Generator

JYH Big Engineering & Consultants brings the best Cryogenic Nitrogen Plants offered capacities range from 50 Nm3/hr to 5000 Nm3/hr.

HOW IT WORKS

Liquid Nitrogen plant's operating principle that is based on fractional distillation to enable the production of nitrogen with high purity. The atmospheric air is sucked up by an air compressor is taken into the air purification system where the impurities like hydrocarbons, moisture as well as carbon dioxide, are eliminated. The air then passes through heat exchangers, where it is then cooled down to the cryogenic temperature. Then, nitrogen is pumped into the distillation column , where the nitrogen gas is separated physically from all other gases and located on the upper part in the column. The nitrogen is then removed from the column and transferred to a low pressure columns where it is distilled until it is in compliance with commercial standards for purity.We are top manufacturer of Cryogenic Nitrogen Generator , Contac us if you urgent need.

Nitrogen Gas Firefighting System

Nitrogen fire fighting system commonly used in power transformers at Power sub stations. Nitrogen Injection fire protection system(NIFPS) prevents explosions or rapture and possible oil fire in event of minor nature of arcing due to internal faults or external faults in transformers oil tanks. In case of rise in Temperature inside Transformer due to various reasons, PLC based NIFPS system receives internal inherent Faults / Feedback / Trip Signals from Transformer Panel. In case of any incident PLC based NIFPS system activates electrically operated Transformer Conservator Isolation Valve / Oil Drain Valve / Nitrogen Injection Valve etc. which Isolate the Oil Conservator Tank from main Tank, drains out oil from Transformer into the Oil Pit and Nitrogen gas is injected which creates a layer rest of the oil to avoid any contact with Atmospheric Oxygen.

ADVANTAGES OF Nitrogen Injection Fire Prevention System (NIFPS)

i) Low investment cost as compared to other conventional system.

ii) Very low post fire and no secondary damages.

iii) Minimum maintenance and running cost.

iv) No climatic effects.

v) Suitable for indoor / outdoor installation.

vi) Minimum space requirement.

vii) Multi signals for activation, eliminates false alarms.

viii) Allows system testing on operational transformer not possible with conventional fire system.

ix) No moisture absorbing in inside the transformer due to presence of nitrogen.

x) Great saving in cost, due to absence of moisture.

xi) Fully automatic, unattended and a fool proof system.

xii) It can be operated manually / automatically, local / remote control.

xiii) No water reservoir or major civil work required.

xiv) Prevents transformer explosion ensuring system remains functioning.

xv) Prevention of unplanned outages.

xvi) Considerable savings. xvii) Improves overall power system reliability.
