Nitrogen Gas Application

Nitrogen is an inert gas that is suitable for a wide range of applications, covering various aspects of chemical manufacturing, processing, handling, and shipping. Nitrogen is not reactive and it is excellent for blanketing and is often used as purging gas. It can be used to remove contaminants from process streams through methods such as stripping and sparging. Due to its properties it can be used for protection of valuable products against harmful contaminants. It also enables safe storage, usage of flammable compounds and can help prevent combustible dust explosions. The applications of nitrogen compounds are naturally extremely widely varied due to the huge size of this class: hence, only applications of pure nitrogen itself will be considered here. Two-thirds of nitrogen produced by industry is sold as the gas and the remaining one-third as the liquid. The gas is mostly used as an inert atmosphere whenever the oxygen in the air would pose a fire, explosion, or oxidising hazard. Some examples include:

Food industry

Nitrogen gas is also used to provide an unreactive atmosphere. It is used in this way to preserve foods. As a modified atmosphere, pure or mixed with carbon dioxide, to nitrogenate and preserve the freshness of packaged or bulk foods (by delaying rancidity and other forms of oxidative damage like changing colours). Pure nitrogen as food additive is labelled in the European Union with the E number E941.

Light bulbs industry

Bulbs should not be filled with air since hot tungsten wire will combust in presence of oxygen. You can’t maintain vacuum either or external atmospheric pressure will break the glass. So, they must be filled with non-reactive gas like nitrogen. We can use inert gases like argon or helium instead of Nitrogen, but they are more expensive & rarer than nitrogen.

Fire suppression systems

Fire suppression is achieved by reducing the oxygen concentration where the fire will extinguish, while remaining at a level acceptable for human exposure for a short period of time.

Stainless steel manufacturing

There are various instances when nitrogen can be added to steel during steelmaking such as melting, the ladle processing and the casting operations. Nitrogen effect on hardness, formability, strain ageing and impact properties.

Tire filling systems

Nitrogen is used to inflate race car and aircraft tires, reducing the problems caused by moisture and oxygen in natural air. Nitrogen is less likely to migrate through tire rubber than oxygen, which means that your tire pressures will remain more stable over the long term. That means more consistent
