What is Nitrogen?
Nitrogen is a chemical element with symbol N. The symbol N2 is also widely used and accepted within the industry. Nitrogen is a colourless, odourless and tasteless gas. N2 constitutes 78.09% by volume of the air we breathe. Nitrogen was discovered in 1772 by a Scottish Physicist, David Rutherford.
Nitrogen is an inert gas, widely used in oil and gas industry for its properties. Nitrogen can be found in all living organisms as well as many compounds such as ammonia, nitric acid and others. The majority of nitrogen currently produced worldwide is preformed via cryogenic separation of air. To produce nitrogen, simply supercool air to a liquid state. In liquid state, the different gases stratify, meaning that nitrogen will automatically be separated from other gases. One can compare this to water and oil when poured into a in a glass (try it if you are unsure, but water will not mixed with oil and one of the two liquids will be at the bottom while the other one at the top). When nitrogen is supercooled, it is then extracted in a liquid form.
Local Nitrogen generators are now becoming the norm across the industry. As they can produced nitrogen at low cost locally for local use, it is understandable that many are now purchasing onsite nitrogen generators. These N2 generators separate the nitrogen gas from ambient air through the use of a membrane or via a Pressure Swing Adsorption (PSA). Nitrogen generators benefit from their small footprint while able to produce substantial amount of nitrogen. However, one has to remember that each nitrogen generator needs an air compressor in addition to a potential nitrogen compressor. The role of the air compressor is to compress ambient air through the membrane or PSA. The role of the nitrogen compressor is to compress the nitrogen gas into a nitrogen storage system at a given pressure such as 200 bar.
Safety, Storage & Handling of nitrogen products:
Nitrogen, in gaseous form, is widely stored in high pressure nitrogen storage cylinders, tubes or tube trailers. In liquid form, nitrogen is mainly stored at the consumer site in cryogenic liquid tank or cylinders. These tanks are highly insulated and specifically designed to reduce evaporation of the nitrogen gas. Liquid nitrogen is dangerous and therefore only trained individuals must handle it with care. The handling of nitrogen liquid gas is risky and therefore all precautions must be taken to avoid any accidents.
Nitrogen in air detection unit is highly advisable. In the occurrence that levels of nitrogen become too high in confined spaces (say a room) it may lead to asphyxiation. As a rule of thumb any nitrogen system (Nitrogen compressor, Nitrogen generator, etc) should be located in a highly ventilated area. A nitrogen monitoring system is also highly advisable to reduce risks associated with nitrogen handling, production and storage.
To dispose nitrogen gas from pressurised nitrogen vessel, on should vent the nitrogen slowly to a well-ventilated outdoor location remote from personal work areas and building air intakes. Usually a nitrogen pipe is used to direct the nitrogen to a safe venting place. As for liquid nitrogen, first allow the N2 to evaporate. Liquid nitrogen boils quickly, so there should not be issue to get it to transform to its gaseous form state.
