JYH Big Engineering & Consultants

We are engaged in offering Nitrogen Gas Generators to our clients. Our range of all products is widely appreciated by our clients.

We are engaged in offering 100 LPM Nitrogen Generator to our clients. Our range of all products is widely appreciated by our clients.

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 :

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

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

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

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.

We are engaged in offering Membrane Type Nitrogen Generator to our clients. Our range of all products is widely appreciated by our clients.

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.

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 :

 Serves as coolant for computers and vacuum pump systems
 Cooling of superconductors
 Storage of foods for food preservation
 Cryopreservation of blood
 Cryosurgery for removing dead cells from brain
 Preservation of semen of animals
 Working substance for liquid nitrogen power vehicle and much more
 Cryo treatment of various metals to improve the properties

HOW IT WORKS

Liquid Nitrogen plant working principle based on fractional distillation for generation of high purity nitrogen. Atmospheric air sucked by an air compressor and sent into the air purification unit where impurities such as moisture, hydrocarbons and carbon dioxide are removed. Afterwards the air is passed through heat exchangers where it is cooled to cryogenic temperatures. At this point, nitrogen is directed into the high pressure distillation column where nitrogen is physically separated from other gases and is formed at the top of the column. Nitrogen is removed from the column and is moved to low pressure column where it is distilled till it meets the commercial specifications for purity.

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.
