Industrial Uses for Pressurized Nitrogen Gas

Pressurized nitrogen gas may not make headlines, but it drives countless industries worldwide. From manufacturing to food processing, its applications are vast. This blog discusses the most important industrial uses for pressurized nitrogen gas, detailing its applications and benefits. By the end, you’ll have a deeper understanding of how we use it and why.

1. Food Preservation

Nitrogen gas is common in modified atmosphere packaging (MAP), a technique that replaces oxygen in food packaging to extend shelf life. This approach is especially common for items like chips, nuts, and pre-packaged fruits or vegetables.

By displacing oxygen, nitrogen preserves freshness while maintaining flavor and texture. Nitrogen is also common in the beverage industry to carbonate certain drinks, such as stouts and nitro coffee.

2. Chemical Processing

Nitrogen is also popular throughout the chemical industry, particularly as an inert atmosphere for chemical reactions. Its unreactive nature prevents unwanted side reactions, ensuring the purity of sensitive processes.

Nitrogen blankets storage tanks and pipelines to safeguard reactive substances from oxidation or contamination. With the addition of N2 booster pumps or compressors for application, crews can ensure they get the results they want.

3. Oil, Gas, and Chemical Industries

Nitrogen can purge systems, such as pipelines and storage tanks, of oxygen and moisture, minimizing the risk of oxidation or flammable reactions. Nitrogen blanketing creates an inert “protective blanket” over volatile substances in chemical storage tanks, reducing evaporation and explosion risks.

In addition, advanced oil recovery techniques use pressurized nitrogen gas. By injecting nitrogen into wells, it builds pressure to extract oil more efficiently.

4. CNC Machining

Nitrogen is an important component in CNC (computer numerical control) machining processes, where it creates a controlled atmosphere. Its use prevents oxidation during machining operations, especially for materials like titanium or stainless steel that are sensitive to oxygen exposure.

Nitrogen also powers pneumatic systems or acts as a coolant to maintain the precision of the machinery by reducing thermal distortion. While there are so many fabrication materials that can be used in CNC machining, nitrogen enhances the quality and consistency of finished components.

5. Medical and Pharmaceutical Industries

Nitrogen’s ability to exist at extremely low temperatures in its liquid form (-196 degrees Celsius or -321 degrees Fahrenheit) makes it invaluable for cryopreservation. It stores biological specimens such as blood, tissues, and even reproductive cells over long periods.

Furthermore, pharmaceutical companies use nitrogen to displace oxygen during medicine production and packaging, preventing microbial contamination and ensuring the medicine retains its efficacy.
