What Are the Most Common Uses of Dry Nitrogen Gas?
Nitrogen is an inert gas that does not easily react with other chemicals. So, it is highly preferred for many industrial applications. MVS Engineering Pvt. Ltd offers nitrogen generators that supply to meet all types of nitrogen gas uses. All these models of nitrogen gas plants produce 95% to 99.9999% pure nitrogen. The dew point can go up to (-) 80°C and the amount of oxygen present can be only 1-ppm. Thus, all properties of nitrogen can be utilized for industrial purposes.
Few industrial applications of nitrogen gas
Many industries need pure nitrogen for various purposes. MVS Engineering is well aware of all nitrogen gas uses and customizes its nitrogen plants accordingly.
Food packaging – When food materials are packed in the atmosphere of nitrogen, oxidation, and rancidity of foods can be avoided. Thus, the freshness of foods can be maintained with their original colors and odors within their packages until packs are opened for consumption. Nitrogen is allowed now to be used as an additive or preservative in many readymade foods. Breweries also use nitrogen to protect their products from staling.
Filling tires of vehicles – The tires of racing cars are usually filled with nitrogen gas. The presence of oxygen and water vapor can reduce the longevity of rubber tires. Thus, pure dry nitrogen is the best option in this regard. Large tires of mining trucks and aircraft are also filled with nitrogen, to maintain the desired air pressure and stability of those tires. As nitrogen is heat-resistant, tires remain inflated even when heated up due to frictional force while running. So, the stability of tires can be guaranteed when filled with dry nitrogen.
Adding to fuel tanks – Usually, fuels used in automobiles and aircraft are highly inflammable, which is risky. Thus, it is advised to add nitrogen gas to these fuel tanks, to reduce the combustibility of fuels. The presence of nitrogen minimizes the risk of accidental fire and other similar hazards.
Electric bulbs manufacturing – Electric bulbs contain tungsten wires, which illuminate to produce light. These tungsten wires can react with the oxygen present in the air, resulting in combustion. So, it is best to fill bulbs with an inert gas to drive out oxygen. Helium, argon, and nitrogen are three inert gases fit for this purpose. But helium and argon are very rare and expensive. So, dry nitrogen is the best option in this case.
Producing chemical products – Many chemical industries need nitrogen to produce concentrated liquid samples for detailed analysis. Various chemical products, like fertilizers, dyes, explosives, nylon, and nitric acid are produced with the help of pure nitrogen. Volatile chemicals can be handled safely when used in the inert atmosphere of nitrogen.
Manufacture of Metals – Nitrogen is necessary in different stages of metal manufacturing or Heat treatments. The melting of iron, ladle transporting, and casting into molds demand the presence of nitrogen gas.
All these and many more nitrogen gas uses can be fulfilled only by the installation of onsite nitrogen generators, supplied by MVS Engineering.
