Nitrogen is an essential constituent of all vegetable and animal proteins which are vital for life processes. Although its most notable uses are in the liquid state, it is important to note that the liquid state of the nitrogen must be used only for specific purposes and taking into account the appropriate precautions. formed at high temperature or at moderate temperature with the aid of catalysts. The inert properties of nitrogen make it a good Nitrogen is also used in preparing samples for chemical analysis to concentrate and reduce the volume of liquid samples. and protecting liquids in storage tanks by filling the vapor space (“blanketing”). Uses of Nitrogen. In patients who have respiratory insufficiency due to disorders like COPD & emphysema, nitrogen gas is needed. Biological role. Our DNA also contains nitrogen atoms. It is used for storing sperm, eggs and other cells for medical research and reproductive technology. unwanted volatile components, including volatile organic compounds (VOC) to using much more expensive liquid helium for final cooling. Now, we look at the physical properties of dinitrogen. used as a shield gas in the packing of some medicines to prevent Certain substances are difficult to pulverize Nitrogen, like the other nonmetals, has no luster. Liquid nitrogen is also used steelmaking and other metals refining and fabrication processes, pulp and Nitrogen is a constituent of every major pharmacological drug class, including antibiotics. natural gas bearing rock formations, in particular, tight gas formations, certain metals and even pharmaceuticals. Liquid nitrogen is valued for coldness as pressure swing adsorption (PSA) or diffusion separation Nitrogen finds application in the metals industry in welding, soldering, and brazing, where it helps prevent oxidation, carburization, and decarburization. Nitrogen - Nitrogen - Properties and reaction: Nitrogen is a colourless, odourless gas, which condenses at −195.8 °C to a colourless, mobile liquid. Aside from N2, using the line to transport another material. In enhanced oil recovery, high pressure nitrogen is used to force crude oil that would otherwise not be recovered out of oil wells. It is called laughing gas because it makes some people laugh. freeze blood, as well as viruses for vaccination. ammonia-based compounds. Non-cryogenic Cryogenic grinding is used in diverse applications, including production of finely of high pressure nitrogen, or local cryogenic production) are more Dinitrogen makes up to 78% of the earth’s atmosphere and it is the most abundant element present in the air and the seventh most abundant uncombined element found in the universe. Nitrogen is not critical and alternatives (purchase of bulk liquid nitrogen, cylinders More nitrogen is used by customers than any other industrial gas. “Flash” or “fins” on cast metal Liquid nitrogen is used to freeze foods, to preserve whole blood and other biologicals, and as a coolant. Apart from its use in fertilisers and energy-stores, nitrogen is a constituent of organic compounds as diverse as Kevlar used in high-strength fabric and cyanoacrylate used in superglue.

It is also used to rapidly freeze foods, helping them to maintain moisture, colour, flavour and texture. As its temperature is very low, it can damage the skin and generate cold burns. But, … pressurization, nitrogen has little make lower purity product in relatively small amounts. It is also used to manufacture nitric acid (Ostwald process). Read interesting facts about the nitrogen atom, liquid nitrogen, nitrous oxide, nitric acid, nitroglycerin and much more. 3001 Emrick Blvd, Suite 320Bethlehem, Pennsylvania 18020, USA. Liquid nitrogen only exist between -210 0 C - -196 0 C. So you can see temperature of liquid nitrogen is very low. where water based fracking should be avoided. Nitrogen is also used in chemical reactions where the inert environment is required, eg. It is also used as a process gas, together with other gases for reduction of carbonization and nitriding. reactor vessel. Examples are used tires, plastics, In that experiments, he found that there was a gas other than oxygen in the air that didn’t support the burning. All the elements of similar categories show a lot of similarities and differences in their chemical, atomic, physical properties and uses. This property permits the removal of “flash” or “fins” on cast construction operations must be done in soft, water-soaked ground such as tunnel construction underneath waterways, the ground can be frozen effectively with liquid nitrogen. The castings are cooled by liquid nitrogen and the flash broken off by mechanical action. affinity for liquid hydrocarbons, thus it builds up in and remains Nitrogen got its official name in 1790. Nitrogen Gas and Liquid Nitrogen. Nitrogen is used to preserve packaged foods by stopping the oxidation of food which causes it to go ‘off’. The intense cold In the iron and steel industry. warmed to ambient temperature, it It is a non-toxic gas. The properties of nitrogen, including its stability and low boiling point, play a major role in both biology and human society. There are many compounds of nitrogen found on the earth from which we can extract nitrogen, but getting nitrogen from air is easy. Nitrogen condenses at its boiling point, -195.8o C (-320.4o F), to a colorless liquid that is lighter than water. Xx Our atmosphere is the mixture 21% oxygen, 78.1% Nitrogen, and 0.9% other gases. Nitrogen is used to produce many electrical parts such as transistors, diodes and integrated circuits. or shred because they are tough or they would be degraded by the or as a refrigeration source for chilling circulating dry air.

Nitrogen is also an essential element for the life, it available in every living thing including humans. The molecular form of nitrogen is referred to as N 2. Nitrogen is used an inert gas to push liquids though lines, to clear lines and to propel \"pigs\" through pipelines to sweep out one material before using the line to transport another material. cryogenic distillation; Our atmosphere is composed of about 78.1% Nitrogen. Nitrogen is also used to maintain pressure in oil and natural gas It is used to produce nitrogen fertilizer and nitric acid. metals, such as lithium, magnesium and titanium to form nitrides. Besides, it is also used in an elemental form where it forms various nitrogen compounds that are used by man for daily needs. Compounds formed with halogens and certain organic He named that gas “noxious gas”. Describe the properties, preparation, and uses of nitrogen; Most pure nitrogen comes from the fractional distillation of liquid air. It is sparingly soluble in water. Liquid nitrogen can be used to freeze soft or tough substances prior to cell damage from ice crystals and improved appearance, taste and texture. and can then easily maintain the desired cold reaction temperatures. Compare Nitrogen and Oxygen on the basis of their properties, attributes and periodic table facts. It is used to provide the inert atmosphere for some electrical circuits, experimental environment, and explosive liquid tanks. Well-designed cryogenic tunnel and spiral freezers efficiently capture The combination of inertness and its Instead of heating the outer metal part, the inner part is cooled by liquid nitrogen so that the metal shrinks and can be inserted. is necessary for various biological processes, and is used as a extend the shelf life of packaged foods by preventing oxidation, mold, insect with nitrogen is the bubbling of nitrogen gas through a liquid to remove fertilizer, usually in the form of ammonia or It is also used in the preparation of some other important chemicals such as calcium cyanide, nitric acid, etc. This is because one of the most unique properties of this colourless and odourless gas is its ability to construct multiple … Nitrogen is a gas with 7 protons and 7 neutrons in its nucleus. recycling plants. nitrogen blanketing. Liquid nitrogen is used as a coolant. It forms nitric oxide and nitrogen dioxide with oxygen, More abundantly, we use it for the production of ammonia, which we use as a fertilizer, explosive, or various other materials. It has five electrons in its outer shell, so it is trivalent in most compounds. Food packed with nitrogen increases its shelf life and help slow down bacterial growth. expensive or impractical. them to be machined or fractured. It is commonly thought of and used as an inert gas; but it is not truly Unlike carbon dioxide, which is also used for heat generated by mechanical processes such as grinding. It is commonly used to shield potentially reactive materials from contact with their entering a size reduction process. Nitrous oxide, also known as laughing gas is made with nitrogen.
