Nitrogen is an abundant chemical component of the atmosphere. It occupies the largest percentage of it and is normally represented by the capital letter N. It has properties that makes it very useful in the industries. Chemical inertness is the property that proves to be the most essential. Nitrogen generators are used to produce N2 gas that can be used for other purposes.
The generators are found in various forms and utilize two main technologies. The first is the adsorbent technology. It utilizes an adsorbent which is a solid substance used in the process of obtaining pure N2. Adsorbent plants are quite a number, though the most commonly used is the PSA, pressure swing absorbent. The operating cost of the adsorbent is low and in turn the price of nitrogen produced is also low.
The other is the membrane technology. It is further divided into membrane cartridge and gas separation concept. The gas separation process occurs when the velocities at which pressurized air penetrates a certain membrane are used to differentiate the gases. The difference in speeds is what brings about the separation.
The membrane cartridge functions in a different way. Compressed air is forced through a hollow tube that allows the other elements to be absorbed or separated at the sides of its walls. The elements include oxygen, water vapor, inert or rare gases and other impurities that are found in air. When all these are removed from air, pure nitrogen is obtained.
The generators are applied in many fields. The food industry suffers a lot from the decay of food substances and food rotting. A large supply of nitrogen gas is needed to prevent oxidation that causes food to rot. In so doing, the lifetime of these products is stretched out. The presence of these gas prevents the continued existence of bacteria that fasten the decaying process. It is very vital in preservation of food.
In the locomotives industry, compressed air is normally used to fill car and aircraft tires. When the compressed air is used, there is presence of water in the tires. To avoid this, a nitrogen generator is preferred because it can produce dry gas unlike the compressed air tank.
In the petroleum industry it is used for more than one purposes. It is incorporated while transporting hydrocarbons or the various petroleum products. It is then used to examine the efficiency of the pipelines. Most importantly, it is used to safeguard the environment. It prevents outbreaks of fire because of its inertness and does not support combustion.
The paint and pharmaceutical industry also uses it. Explosions may occur in the pharmaceutical industry due to the presence of flammable chemicals. Nitrogen prevents these occurrences. In packaging of the paints and vanishes in the paint industry, it is useful to prevent the drying oils from polymerization. It does so by displacing the oxygen present.
The generators as seen above are applied in very many fields. The properties of N2 gas have proved to be very essential to the lives of every person. It has promoted the development of various industries and have had a great impact to the human race.
