Gaseous nitrogen is a highly sought-after chemical molecule used in various industrial manufacturing processes. Thanks to its inert properties, nitrogen gas is ideal for applications in food processing, the beverage and brewery industries, and oil and gas recovery, among others. This article will explore the most common industrial uses of nitrogen gas and the products derived from its application.
Nitrogen gas, or N₂, consists of diatomic molecules formed when two nitrogen atoms bond together. It is colorless, odorless, and chemically inert, making it ideal for industrial applications where chemical reactivity between materials must be avoided.
Nitrogen gas has a wide range of applications in various industries. Let’s explore some of the most common uses of nitrogen gas in industrial settings and highlight some of the typical nitrogen gas products available.
N2 Industrial Gas is widely used in the production of various foods and beverages. For instance, gaseous nitrogen is used in sparging alcoholic beverages to achieve a higher-quality brew. Additionally, N₂ gas is employed in modified atmosphere packaging to extend the shelf life of commercially produced food products.
Due to its non-reactive nature, nitrogen gas is perfect for use in industrial settings with a high risk of spontaneous combustion. In chemical plants where there is a high risk of explosions, nitrogen gas is used to displace oxygen from process equipment, enhancing safety.
Nitrogen gas offers superior pressure retention in tires compared to conventional air-filled tires, leading to improved fuel efficiency and extended tire lifespan.
Industrial wastes often contain VOCs, making them unsuitable for direct disposal. Nitrogen gas can be used to remove these unwanted VOCs from waste materials, helping operators comply with environmental protection standards in their respective regions.
Mining is a high-risk industry that requires strict safety protocols. Nitrogen gas can be used to extinguish fires in mines by displacing oxygen from the air, thereby reducing the risk of combustion. A similar method is applied during mine abandonment, where nitrogen gas is pumped into potentially volatile areas to make them inert and safe.
Nitrogen gas is widely used in the production of electronic components for various devices. Using nitrogen gas in soldering processes ensures a high-quality finish for electronic parts.
In metal manufacturing, nitrogen gas is also used in steel electroplating, providing a strong, durable, and corrosion-resistant finish.
Nitrogen molecules are a fundamental component in nearly all synthetically manufactured drugs. Nitrogen gas is essential in the synthesis of various drug classes, including critical antibiotics. Additionally, nitrous oxide, a commonly used anesthetic, is derived from nitrogen gas.
The most common categories of nitrogen gas products are highlighted in subsequent sections of this article.
Nitrogen gas membrane technology enables the separation of gas mixtures based on the different speeds at which gases pass through the membrane. These membranes are made from polymeric materials with hollow fibers, providing a large surface area for efficient gas separation.
Nitrogen gas membranes are capable of achieving high-purity nitrogen by selectively retaining nitrogen while allowing oxygen and other gases to pass through.
Producing nitrogen gas with the necessary purity for industrial applications requires precise control. The efficiency of nitrogen gas production can be enhanced by monitoring and adjusting key variables, such as:
- The temperature of the feed gas
- The pressure of the feed gas
- The oxygen content in the product gas
This strict control can be achieved using oxygen gas analyzers and proper regulation of feed gas valves.
As mentioned earlier, nitrogen gas has a wide range of industrial applications. Here are additional uses not previously covered:
- Inerting systems in the gas and oil industries
- Enhanced oil recovery
- Offshore inerting systems
- Hydrogen gas purification
- Industrial gas purging and blanketing
- Natural gas dehydration
