Nitrogen (N₂) – Nitrogen Gas Definition – Nitrogen Symbol – What is Nitrogen

Nitrogen is an odourless, tasteless and colourless gas at standard temperature and pressure. Nitrogen atoms typically bond with another nitrogen atom forming the N₂ nitrogen molecule. You find nitrogen in many explosives because of the strength of this molecular bond.

Dinitrogen is a diatomic gas, with 2 trivalently-bonded nitrogen atoms and a molecular formula of N₂.

Nitrogen symbol is N₂. Nitrogen atomic number is 7.

Nitrogen gas is also very versatile. Nitrogen gas can be used to inflate tyres, replace oxygen in food packaging and purge dangerous gas from enclosed spaces whilst liquid nitrogen can fast freeze food and is even used in some medical procedures.

Nitrogen gas (N₂) is supplied in G2 and E2 nitrogen cylinder sizes.

Nitrogen Uses – What is Nitrogen Gas Used For – Industrial Nitrogen Gas Bottles

Nitrogen is a multipurpose gas supplied in handy nitrogen gas bottles. Applications include tyre filling, food packaging, gas purging and winemaking. Nitrogen gas bottles come in industrial grade and food grade purity options.

Industrial nitrogen gas is used for nitrogen in tyres. Industrial nitrogen uses also include the production of ammonia (NH3), a colorless gas used in making fertilizers. Ammonia is also used as a disinfectant.

Nitrogen in Tyres

Industrial nitrogen in tyres (tires) is used to fill tyres, in lieu of air. It aids in longer lifer by reducing oxidation. Pressure retention is also superior, providing better wear and petrol mileage. Nitrogen in tyres is supplied in G2 and E2 nitrogen cylinder sizes.

Industrial Nitrogen is Used for Purging – What is Nitrogen Purging

Nitrogen purging is an industrial procedure used to replace unwanted or hazardous gases with an inert dry gas – nitrogen. Industrial nitrogen for purging is supplied in G2 and E2 nitrogen gas cylinder sizes. Nitrogen can be used to purge air (oxygen) to reduce oxidation. It can also be used to purge things like LPG tanks, to make them safe from any possible explosion.

Is Nitrogen Flammable

Nitrogen is not flammable. Nitrogen will not burn by itself nor support combustion. Nitrogen, when combined with oxygen as air, will support combustion.

Nitrogen is flammable with oxygen or air, and has a flammable range of from 4.1% to 74.2%, by volume in air. A mixture of 10% to 65% hydrogen by volume in air will explode if ignited. Hydrogen will combine with nitrogen, under the proper conditions, to form ammonia.

The density of Nitrogen at STP

The density of nitrogen is 1.2506 g/L at 0°C (32°F) at 1 atm.

Nitrogen Properties – Industrial Nitrogen Facts

• Nitrogen is odourless and colourless
• Nitrogen is inert
• Industrial nitrogen is supplied in G2 and E2 nitrogen gas cylinder sizes.

Is Nitrogen Explosive

Nitrogen is not explosive nor flammable. Nitrogen is inert and extremely stable.

Nitrogen Bottles Sizes – Nitrogen Gas Cylinder Sizes

The smallest nitrogen bottle we offer at Stargas is an E2 nitrogen bottle size which contains ≈ 4.5m3 at (20000kPa) and a weight of 24.5kg. In comparison, a G2 nitrogen bottle sizes contain ≈ 9.1m3 at (20,000kPa) and a weight of 54kg.

Nitrogen bottle sizes (nitrogen cylinder sizes) are steel vessels for storing compressed nitrogen gas. The gas contents of nitrogen gas bottle sizes (nitrogen cylinder sizes) are measured in cubic metres (m³). The nitrogen bottle size outlet connection is AS 2473 Type 50. Larger commercial users have bulk nitrogen tanks.

G2 nitrogen bottle sizes contain ≅ 9.1m³ at (20,000kPa)

E2 nitrogen bottle sizes contain ≅ 4.5m³ at (20000kPa)

Nitrogen Cylinder Sizes – Nitrogen Gas Cylinder Sizes – Nitrogen Bottle Sizes

Nitrogen cylinders are supplied in two nitrogen gas cylinder sizes to meet your needs. Nitrogen gas cylinder sizes (nitrogen bottle sizes) include G2 and E2 nitrogen cylinder sizes. Nitrogen is inert to virtually all substances at ambient temperatures and conditions.

Nitrogen gas cylinder sizes include welding gas cylinder sizes – welding bottle sizes, cylinder capacity & gas bottle dimensions.

Nitrogen Gas Cylinder Sizes – Industrial Nitrogen Gas Bottle Size Hire & Refill

Nitrogen gas cylinder sizes include G2 and E2 sizes. G2 nitrogen gas cylinder sizes contain ≈ 9.1m3 at (20,000kPa). E2 nitrogen gas cylinder sizes contain ≈ 4.5m3 at (20000kPa). Get industrial nitrogen gas cylinder sizes to hire and nitrogen gas refill in all nitrogen gas cylinder sizes.

Is Nitrogen Poisonous

Nitrogen is not poisonous. Whilst not poisonous, pure nitrogen is an asphyxiant, due to the lack of oxygen. Contact with liquid nitrogen can cause cold burns and frostbite.

Chemical Equation for Nitrogen Gas – Is Nitrogen Gas a Compound

The chemical formula and elemental symbol of Nitrogen are N. The molecular formula for Nitrogen gas is N₂. So, nitrogen gas is a single element and not a compound.

Nitrogen Composition in Air

Nitrogen composition in the air is 78.1% of our atmosphere. Nitrogen is the most common gas in air, followed by oxygen at 20.95%. The rest are all less than 1%, with argon at 0.93%, carbon dioxide at 0.04% and just small traces of other gases.

Where Do We Get Industrial Nitrogen From – Air Separation Unit (ASU)

We get industrial nitrogen from the air around us. Air separation plants use cryogenic distillation to isolate the nitrogen. The process that chills the air to extremely low temperatures so the component gases (nitrogen, oxygen, argon, xenon, neon and krypton) can be separated. An air separation unit (ASU) is a major industrial plant for producing large commercial quantities of nitrogen (see accompanying image).

There are other processes that can be used including membrane-based generators and pressure swing absorption (PSA) generators. Both of these techniques use fairly small-sized equipment that can be used as on-site nitrogen generators.

Industrial Nitrogen Gas Bottle Suppliers

Get industrial nitrogen gas bottle supply for tyre inflation, purging, food packaging, blanketing, winemaking, and many other applications that require inert gas. Food-grade quality nitrogen gas, in convenient nitrogen gas bottle sizes, is also used to mix with Carbon Dioxide for beer dispensing.

Nitrogen Cylinder Pressure Bar or kPa – Nitrogen Regulator

Nitrogen cylinder pressure in the bar is 163 bar – 200 bar. The gauge pressure: 16,300kPa – 20,000kPa. A nitrogen regulator is used to reduce the nitrogen cylinder pressure bar to make it practical and safe to use

Food Applications for Nitrogen:

Nitrogen gas is mixed with Carbon Dioxide for beer dispensing. Certain foods packages are filled with nitrogen gas to prevent oxidation.

Industrial Nitrogen Gas Bottle Applications:

Industrial nitrogen gas bottles are used for blanketing and purging applications to displace or dilute all unwanted gas or vapour. Industrial nitrogen bottles is also widely used for reasons of safety and the prevention of product degradation in the chemicals and petroleum industry. Other applications for industrial nitrogen gas bottles include:
