Nitrogen, a colorless, odorless gas, is chemically inert. Nitrogen (N₂) Industrial Gas is one of the most widely used industrial gases due to its inert properties, making it essential in various applications across different industries. As a colorless, odorless, and tasteless gas, nitrogen is naturally abundant in the Earth's atmosphere, comprising about 78% of the air we breathe.
Chemical Formula: N₂
Inertness: Nitrogen is chemically inert, meaning it does not easily react with other substances under standard conditions. This makes it ideal for applications requiring a non-reactive atmosphere.
Non-Flammable: Like carbon dioxide, nitrogen is non-flammable, adding to its versatility in different industrial settings.
Colorless, Odorless, and Tasteless: It does not impart any color, odor, or taste.
Non-Toxic: Nitrogen is non-toxic, but in high concentrations, it can displace oxygen and cause asphyxiation, particularly in confined spaces.
Cryogenic Risks: Handling liquid nitrogen requires caution due to its extremely low temperature, which can cause severe frostbite or cold burns on contact.
Used to produce ammonia, nitric acid, nitrate, cyanide and so on.
