Nitrogen is the dominant element found in almost everything - from the solar system to all life on Earth. So, what is nitrogen used for now? Since its initial discovery, nitrogen has become an important part of the industry. As such an abundant and versatile compound, nitrogen performs multiple functions in multiple industries and has become an essential resource. Traditionally, the vast majority of businesses have relied on purchasing nitrogen or liquid in bulk cylinders to meet their nitrogen supply needs, but the process has had a significant impact on the environment.

How is nitrogen used in different industrial applications?

Nitrogen is available in gas or liquid form and is commonly used for many industrial purposes as well as our daily needs. Read on to learn about 5 important industrial uses of nitrogen:

1. Healthcare: In the healthcare industry, nitrogen gas is used as a substance for freezing and preserving substances such as blood, tissue, and other biological samples. Nitrous oxide can also be used as an anesthetic. Additionally, it can be used as a medical gas in cryosurgery, which involves the use of nitrogen gas to remove some cancers and skin lesions. Nitrogen is also sometimes used to power certain medical equipment.
2. Pharmaceutical: Nitrogen is widely used in the pharmaceutical industry. It is used to make medicines and is so widely used that it can be found in every major drug class. Raw materials such as inactive ingredients and other chemicals can be extremely sensitive to oxygen, which is where nitrogen comes into play.
3. Aerospace: Safety is one of the biggest concerns when manufacturing and processing industrial autoclaves. Since nitrogen is an inert gas, it prevents the possibility of combustion, which makes it an ideal component for use in systems operating at high temperatures or pressures. Therefore, nitrogen offers a safer alternative to compressed air, especially for the aerospace industry.
4. Oil and Gas: In addition to cleaning and purging pipelines, nitrogen plays a key role in the drilling, workover and completion phases of oil and gas wells. Nitrogen is also used in onshore and offshore applications to help prevent ignition of flammable gases and protect tubular components from corrosion.
5. Plastics: The plastics industry is one of the largest in North America. Typically, nitrogen is used to prevent oxidation and discoloration during manufacturing and to help maintain the integrity of the material.
