Features of Nitrogen Gas
Nitrogen, N2, is usually a colorless and odorless gas. In general, nitrogen is less dense than air. Nitrogen accounts for 78.08% (volume fraction) of the total atmosphere and is one of the main components of air. Under standard atmospheric pressure, when nitrogen is cooled to -195.8 ° C, it becomes a colorless liquid. And when cooled to -209.8 ° C, liquid nitrogen becomes a snow-like solid. The chemical nature of nitrogen is inert and it is difficult to react with other substances at room temperature. So it is often used to make preservatives. Yet, under high temperature and high energy conditions, chemical changes can occur with certain substances to make new substances useful to humans.
Common Industrial Uses for Nitrogen Gas
Nitrogen gas has a wide range of uses in the chemical, petroleum, electronics, food, metal smelting and processing industries.
Filling the oil well with nitrogen can not only increase the pressure in the well, but also increase the oil production. The filled nitrogen can also be used as a cushion in the measurement of the drill pipe. The possibility of squeezing the lower test tube string by the mud pressure in the well is completely avoided. Besides, nitrogen is also used in downhole operations such as acidification, fracturing, hydraulic perforation, and hydraulic packer setting. Filling natural gas with nitrogen can reduce the calorific value. When replacing the pipeline with crude oil, liquid nitrogen can be used to inject the materials at both ends to solidify and block. Using nitrogen for pressure transportation of pulverized coal is safe, convenient and economical.
Nitrogen is the main raw material for the synthesis of ammonia. The nitrogen required for ammonia synthesis does not need to be separated and purified, and is directly derived from air. During the production of ammonia synthesis gas, the oxygen in the air and the hydrocarbon raw materials undergo a high-temperature catalytic reaction. After conversion, decarbonization, and methanation, a hydrogen-based mixture containing a small amount of methane, trace amounts of carbon monoxide and carbon dioxide is generated. Nitrogen and argon in the air do not participate in the reaction, and directly enter the synthesis gas, thereby obtaining ammonia synthesis gas mainly composed of hydrogen and nitrogen. As ammonia, carbon monoxide, and carbon dioxide easily poison the synthesis catalyst, methane and argon-based synthetic inert substances, and a large accumulation will reduce the synthesis efficiency. Purification of synthesis gas using the liquid nitrogen washing process can prolong the catalyst lifetime and improve Ammonia synthesis efficiency.
Nitrogen is also the main raw material for the synthesis of calcium cyanamide, sodium cyanide and silicon nitride.
High-purity nitrogen can be used as auxiliary gas for the production of polyethylene. For example, a polyethylene production line with an annual output of 10 million tons needs to provide 4,400 standard cubic meters of pure nitrogen per hour.
Utilizing the chemical inactivity of nitrogen, nitrogen is filled in the reactors and storage tanks of many flammable liquid substances. Not only does it protect materials from oxidation and maintain product quality. It also ensures safety and prevents combustion and explosion accidents.
Nitrogen is mainly used as protective gas and purge gas in the metallurgical industry. In the process of rolling steel and metal heat treatment, due to the expansion of nitrogen, the high temperature oxidation of the metal is reduced, and the surface is smooth. Filling non-ferrous metal smelting furnace with nitrogen can reduce the amount of oxygen and temperature, reduce oxidation, and improve product purity. Purge the molten steel with nitrogen to reduce the hydrogen content in the steel and increase the strength of the product. Blowing in 86% nitrogen during blast furnace operation can reduce coke consumption and extend service life. Arc plasma
The furnace is filled with nitrogen to produce nitrided high-speed tool steel.
Purge silicon wafers with dry nitrogen in the electronics industry to keep them dry and clean. In the large-scale integrated circuit production process, high-purity nitrogen can be used as a carrier gas, an inert protective gas, and a packaging gas for a chemical reaction gas.
High-purity nitrogen is a commonly used carrier gas in gas chromatography analysis. Liquid nitrogen is an important source of cold in scientific instruments or scientific experiments. For example, the single crystal lithium detector of the EDAX spectrometer needs to be stored and used at the temperature of liquid nitrogen. Many tests are performed at low temperatures, and the cooling capacity is provided by liquid nitrogen in most cases. Liquid nitrogen can be used as a cold source for various cold traps, cold pumps and cryogenic superconductors.
Nitrogen is mainly used as a protective gas in the food industry. For example, in the fruit and vegetable warehouse, nitrogen is filled to expel oxygen, which inhibits the growth of mold and the production and release of ethylene. It delays the metabolism of fruits and vegetables and lengthens the preservation period. In the storage of grain, filling nitrogen can delay aging. For a long time, maintain the aroma of new rice. With the acceleration of the pace of life, fast food is receiving more and more attention. Filling nitrogen in packaging containers can extend the shelf life of these foods. Foods such as fish and meat can be frozen with liquid nitrogen to achieve the effect of rapid freezing, prevent the moisture in the tissue from forming a vitreous body, so that the tissue is not damaged, and the original taste can be maintained after reheating.
In the biological and medical fields, nitrogen mainly uses the low-temperature properties of liquid nitrogen and is inactive and non-toxic. It is an ideal cold source. Liquid nitrogen has been widely used in the preservation of animal semen, human tissue, and surgery.
Liquid nitrogen also has certain applications in the construction field. For example, large-volume concrete exotherms when solidified, and cracks often occur inside to reduce strength. Using liquid nitrogen as a coolant can greatly increase the strength of concrete. Liquid nitrogen has a unique role in salvaging the sunken ship. Liquid nitrogen can generate pressure after gasification and can be used as a power source. Liquid nitrogen is also used in condensing the atmosphere into clouds, simulating the space environment, forming low-temperature wind-driven channels, recovering radioactive waste, removing scale layers on metal surfaces, making ceramic superconducting cables, crushing and recycling waste rubber, and plastic products.
Nitrogen can also be used as a fire extinguishing gas. Filling the bulb with nitrogen or argon alone can extend the life of the bulb.
In short, nitrogen is widely used in the national economy and people’s livelihood. And it is closely related to human life, production activities and scientific experiments.
Flow Measurement of Nitrogen
Even though nitrogen gas is usually considered inert, that doesn’t mean its use doesn’t need to be controlled precisely counting on its use. within the aforementioned example involving nitrogen flushing and food preservation, using an appropriate flowmeter to watch the speed of flow can make sure that a correct amount of gas is dispensed for the precise need. That way packages aren’t overinflated, which may end in wasted gas also as packaging or product damage, while also ensuring enough is added to preserve and protect the food products.
A similar need for precise use is involved when nitrogen is employed to make electrical components, especially when spaces must be filled and therefore the walls are otherwise delicate or sensitive to excess pressure. for instance , an excessive amount of gas forced into a diode could lead on to wreck , rendering the part useless.
Since adding gas to a sealed container increases the pressure, it’s important to watch the speed of flow to stay the associated pressure at the proper level of the aim . At times, an RF pickup is a perfect method for monitoring flow as they’re ready to monitor the speed even at near zero speeds. this will be critical in delicate situations or where the quantity being dispensed in especially small, requiring a coffee speed to avoid overfilling.
