What Is Nitrogen Used For ?

As a gas, NF nitrogen is used as an essential component in various life science processes and as a protection against oxidation and pollution. Due to the inert nature of nitrogen gas, nitrogen gas can be optimized for use in the food, beverage, and brewing industries, as well as oil and gas extraction, to name but a few.

Nitrogen is colorless, odorless, and chemically inert, making it suitable for industrial uses where chemical cross-reactions between substrates are not desired. Nitrogen promotes food storage by preventing oxidative damage that causes food to spoil. Explosive chemical plants can be made safer by using nitrogen instead of oxygen in process equipment. Nitrogen is used to control oxygen levels, humidity and temperature, and to maintain the proper atmosphere for highly sensitive procedures and equipment.


Nitrogen membranes can be used to achieve high-purity nitrogen filtration by selectively retaining the gas while allowing oxygen and other gases to pass through. Nitrogen can be used to remove unwanted volatile organic compounds from waste, enabling operators to comply with relevant environmental standards in the regions in which they operate.

Nitrogen is also used for pollution control, especially to remove volatile organic compounds from liquids. Nitrogen is also used as an injection gas to push liquids through pipes. Nitrogen can also be used as an assist gas for laser cutting and to improve plasma cutting.

It is used as an auxiliary gas to blow out molten material and produces stronger stainless steel or aluminized products that are also more resistant to corrosion. Nitrogen is non-reactive, ideal for coatings, and is often used as a purge gas. Nitrogen is used as an effective means of preventing oxidation and providing a safe and inert atmosphere to “blow out” the gases produced in the furnace. Nitrogen is an industrial gas obtained by fractional distillation of liquid air or by mechanical methods using gaseous air (pressure reverse osmosis membranes or pressure swing adsorption).


Nitrogen also has many uses in various industries, it is used in fertilizers, explosives, compounds such as ammonia and nitric acid, and a building block of all living organisms, especially as an amino acid in DNA. This makes nitrogen so versatile that it can be used in many forms in a variety of industries. Nitrogen (N 2) is a versatile gas used in a variety of applications and industries.

Using the chemical and physical properties of nitrogen, manufacturers can use nitrogen to develop their products. It is used in the manufacture of fertilizers, nitric acid, nylon, dyes, and explosives. Nitrogen can be used in place of or in combination with carbon dioxide to pressurize the kegs of some beers, especially stouts and British ales, by producing smaller bubbles that make the brewed beer smoother and more intoxicating. In addition to using nitrogen in fertilizers and energy storage, nitrogen is found in various organic compounds such as Kevlar, used in high-strength fabrics, and cyanoacrylate, used in superglue.

In its nitrous oxide state, it can be used as an anesthetic to relieve pain and relax patients. In addition to being an oxidizing agent, nitrogen can also be used as a bleach for flour and rocket fuel.


For example, it is often used in wine bottling to move the oxygen inside the bottle to protect the wine from oxidation. Liquid nitrogen is also popular in cocktail making because it can be used to quickly cool glasses or freeze ingredients. Liquid nitrogen is also used to quickly freeze food and help preserve its flavor, texture, moisture and flavor. Liquid nitrogen can be used to freeze and transport food, cryopreservation of biological samples and superconducting refrigerants, vacuum pumps, and cryotherapy to remove skin abnormalities, protect materials from oxygen exposure, and cool materials to facilitate processing or destruction.

According to the Royal Society of Chemistry, liquid nitrogen is often used as a refrigerant, for example to store sperm, eggs and other cells used in medical research or in fertility clinics. Liquid nitrogen is used as a coolant capable of rapidly freezing food and objects in medical research and reproductive technology. Nitrogen is widely used due to the fact that it does not react with other gases, unlike oxygen, which is extremely reactive. From food packaging to pharmaceuticals, nitrogen gas can be found in more places and used for more purposes than you might think.

When there is not enough air in the soil, microorganisms use oxygen from NO3- instead of atmospheric oxygen and quickly convert NO3- into nitric oxide and nitrogen gas (N2). It makes it difficult for both organisms and industry to convert N 2 into useful compounds, but at the same time means that when nitrogen compounds burn, explode or decompose to form nitrogen gas, a large amount of often useful energy is released.


PSA nitrogen generators separate the individual components of air based on their molecular properties and affinity for adsorption media such as zeolite or granular activated carbon (GAC), while membrane generators work by separating pure N2 from the atmosphere using a semi-permeable membrane. Oilfield operators use nitrogen in gas pressure testing of safety equipment such as Explosion-Proof Devices (EPDs), (production) Christmas trees, and pressure vessels. Nitrogen coating or tank coating is the use of nitrogen gas in a storage tank to prevent volatile chemical reactions between volatile chemicals or hydrocarbons by displacing the oxygen present.

Some aircraft fuel systems use nitrogen to reduce fire risk. Nitrogen is commonly used in the sample preparation process in chemical analysis. Nitrogen can also be used to inflate tires instead of compressed air, which helps maintain pressure longer and prolong tire life.
