Advantages of using nitrogen gas in industry

Nitrogen gas plays a crucial role in numerous industries, from keeping your food fresh to ensuring the safety of firefighters.  Traditionally, businesses have relied on external suppliers for this essential gas, but a new option is gaining traction: on-site nitrogen generation. Trimech India, the leading nitrogen gas manufacturers, is revolutionizing how businesses access this versatile element. In this blog, we will be exploring how it’s made, its diverse applications, and the five key advantages of nitrogen gas in different industries.

How Nitrogen Gas Is Made By Different Industries?

Making nitrogen gas on a large scale might sound complicated, but it’s based on some pretty simple ideas. There are three main ways industries create nitrogen gas:

Pressure Swing Adsorption (PSA): 

This method is like a game of tag. Imagine a container filled with tiny beads that love to grab onto oxygen molecules. We pump air into the container, and these beads trap the oxygen, letting the nitrogen pass through. Then, we lower the pressure, and the beads release the oxygen so we can use them again.

Membrane Nitrogen Generation: 

This method is like a filter with tiny holes. Air is pushed through the filter, and the smaller nitrogen molecules zip through faster than the bigger oxygen molecules. This leaves us with nitrogen on one side and mostly oxygen on the other.

Fractional Distillation: 

This is the coldest method. We cool air down so much that it turns into a liquid. Then, we slowly heat it, and different gasses boil off at different temperatures. Nitrogen has a lower boiling point than oxygen, so it separates first, giving us pure nitrogen gas.

Uses Of Nitrogen Gas In Different Industries

  • Food Industry: Nitrogen is a natural preservative, keeping food fresh for longer. It acts as a barrier against oxygen, which can cause spoilage and discoloration. You’ll often find it used in packaging to maintain the quality of chips, salads, and even coffee beans. It’s also used to create the creamy texture we love in whipped cream and ice cream.
  • Steel Manufacturing: Have you ever wondered how stainless steel gets its shine and strength? It is because nitrogen helps in its production. It’s added to the molten steel to remove impurities and improve its properties, making it more durable and corrosion-resistant.
  • Fire Safety: Nitrogen is a firefighter’s friend. It’s used in fire suppression systems to displace oxygen, smothering flames and preventing them from spreading. This makes it a safer alternative to water in some situations, like data centers and museums.
  • Science and Medicine: In laboratories, nitrogen is used to create an inert atmosphere for sensitive experiments. It also helps preserve biological samples like cells and tissues. In the medical field, liquid nitrogen is used to freeze and store things like blood and sperm.
  • Electronics: During the manufacture of delicate electronic components like transistors and diodes, nitrogen creates a protective atmosphere, preventing contamination and damage from oxygen and moisture.
  • Tires: For race cars and airplanes, nitrogen-filled tires are preferred. Nitrogen maintains tire pressure more consistently, improving handling and reducing the risk of blowouts caused by heat buildup.
  • Beer Brewing: Ever enjoyed a creamy stout or ale? That smooth texture is thanks to nitrogen. It’s used to carbonate these beers, creating smaller bubbles that give them a rich, velvety mouthfeel.

Advantages Of Nitrogen Gas In Different Industries

  1. Cost-Effectiveness: One of the most significant advantages of nitrogen gas is its cost-effectiveness. On-site generation eliminates the need to purchase and transport nitrogen gas in cylinders or tanks, which can be expensive and logistically challenging. By producing your nitrogen gas on demand, you can significantly reduce your operating costs over time.
  2. Convenience and Reliability: With an on-site nitrogen gas manufacturer, you have a constant and reliable supply of nitrogen gas readily available whenever you need it. This eliminates the risk of running out of gas, which can cause costly production delays or disruptions. You also don’t have to worry about scheduling deliveries or managing storage space for cylinders.
  3. Enhanced Safety: Nitrogen gas is non-toxic and non-flammable, making it a safer alternative to other gases in many industrial applications. This is one of the major advantages of nitrogen gas. On-site generation eliminates the need to handle and store large quantities of pressurized gas cylinders, reducing the risk of accidents and injuries.
  4. Environmentally Friendly: Traditional methods of nitrogen gas production and delivery can have a significant environmental impact due to the energy required for compression and transportation. On-site generation systems are much more energy-efficient and produce less waste, making them a greener and more sustainable option.
  5. Improved Quality Control: By generating your nitrogen gas, you have greater control over the purity and quality of the gas you use. This is especially important in industries like pharmaceuticals and electronics, where even slight impurities can affect product quality.
  6. Flexibility and Scalability: Nitrogen gas manufacturers can be easily customized to meet your specific needs. As your production demands change, you can adjust the system’s output accordingly, ensuring that you always have the right amount of nitrogen gas available.


Therefore, it is quite clear that many industries rely on this industrial gas for a wide range of applications. The benefits of using this gas are innumerable.  If your business is one of them, you’ve probably dealt with nitrogen gas manufacturers before.  But have you considered the advantages of making your nitrogen gas on-site?
