Liquid nitrogen is used to cool concrete while it being poured and setting up. reactor vessel. Certain chemicals, surfaces of certain applications such as food freezing. Uses of nitrogen gas 1. Nitrogen condenses at its boiling point, -195.8o C (-320.4o F), to a colorless liquid that is lighter than water. their entering a size reduction process. Gaseous nitrogen is used as a filling agent in food industry because its reactivity characteristics are poor. Nitrogen compounds Nitrogen is also an essential element for the life, it available in every living thing including humans. protect against loss of quality by oxidation by expelling any air entrained in the liquid (“sparging”) or shred because they are tough or they would be degraded by the absorbs a large quantity  of heat; allowing temperatures to be reduced Manufacturing Uses for Nitrogen: Nitrogen is used to treat the melt in the manufacture of steel and other metals and as a shield gas in the heat treatment of iron, steel and other metals. Light bulbs may contain nitrogen as a cheaper alternative to argon. Nitrogen tanks are also replacing carbon dioxide as the main power source for paintball guns. including shale gas and natural gas from coal (coal bed methane) steelmaking and other metals refining and fabrication processes, pulp and Biological role. plastics and rubber. Liquid nitrogen only exist between -210 0 C - -196 0 C. So you can see temperature of liquid nitrogen is very low. And when an area is going to be abandoned, they use nitrogen to ensure the area will not explode. The molecular form of nitrogen is referred to as N 2. 3001 Emrick Blvd, Suite 320Bethlehem, Pennsylvania 18020, USA. They have the same physical and chemical properties as well as uses. Liquid nitrogen is used as a coolant. Pipes are driven into the ground, liquid nitrogen is pumped through the pipes under the earth’s surface. Our atmosphere is composed of about 78.1% Nitrogen. Nitrogen finds application in the metals industry in welding, soldering, and brazing, where it helps prevent oxidation, carburization, and decarburization. is necessary for various biological processes, and is used as a Non-cryogenic degradation by oxidation or moisture adsorption. Reactor cooling and But, … Nitrogen is an essential constituent of all vegetable and animal proteins which are vital for life processes. The method of preparation of nitrogen and N 2 (Dinitrogen) is the same. Nitrogen is also used to maintain pressure in oil and natural gas 4. using the line to transport another material. There are many compounds of nitrogen found on the earth from which we can extract nitrogen, but getting nitrogen from air is easy. natural gas bearing rock formations, in particular, tight gas formations, When the metal returns to its normal temperature, it expands to its original size, giving a very tight fit. It is sparingly soluble in water. and to propel "pigs" through pipelines to sweep out one material before formed at high temperature or at moderate temperature with the aid of catalysts. The liquid nitrogen is vaporized in specially-designed It is called laughing gas because it makes some people laugh. Nitrogen is used to produce ammonia (Haber process) and fertilizers, vital for current food production methods. It is used to produce nitrogen fertilizer and nitric acid. substantially and quickly. make lower purity product in relatively small amounts. Uses of Nitrogen. and liquids from contact with air.
