Liquid nitrogen was experimented with a long time ago way back in the 1900’s to power cars, and it did work Nitrogen is a chemical element and it can be represented as N and atomic number of 7. In normal conditions, nitrogen is a colourless, odourless and tasteless gas. It actually makes up about 78 per cent of our surrounding atmosphere and is one of the basic and primary nutrients crucial for the survival of all living organisms. Although there is an abundance of nitrogen in the atmosphere, it is mostly inaccessible in elemental form to most organisms.
Uses in Liquid and Gas Form
Liquid nitrogen can be employed in many instances, such as freezing and the transporting of food products, cryopreservation of biological samples, a coolant for superconductors, vacuum pumps, used in cryosurgery, shielding materials from oxygen exposure and cooling materials for easier machining or fracturing. Other uses are related to fertilizer, dynamite, medical aesthetic and even car racing.
Nitrogen gas is used in food storage to make sure packaged and bulk foods remain fresh. It is also used in the manufacturing of electronic parts, for industrial purposes and many other useful applications. If you are lucky enough to be living in beautiful NSW, ACT or QLD in lovely Australia, and seeking out nitrogen gas suppliers, make sure to use a reliable, renowned and well trusted service. Nitrogen gas is regularly used as an alternative to carbon dioxide for storing beer in pressurized kegs.
Nitrogen Roles – A Closer Look
Decompression sickness (the ‘Bends’) involves nitrogen bubbles collecting in the bloodstream and other vital areas of the body when people depressurize too rapidly from deep water diving.
Light Bulbs
It is often used in making of the humble light bulb. It is used as an inexpensive substitute for argon in incandescent light bulbs.
Packaged Foods
Nitrogen is used to conserve the freshness of packaged foods. Nitrogen can prohibit the oxidation of food, thus delaying rancidity and other forms of oxidative damage.
Fertilizers
It is one of the most crucial ingredients in fertilizers, to aid in increasing soil fertility. Its usage makes other fertilizers like ammonia and urea, which are used to increase promote plant growth and yield.
Electronic Parts
Nitrogen is utilised in the making of transistors, integrated circuits, and diodes.
Stainless Steel
Nitrogen is usually used in the making of stainless steel and electroplating processes so as to make it stronger and more corrosion resistant.
High Voltage Equipment
Pressurized and dried nitrogen gas are used as a dielectric gas for high voltage equipment. It is also used as a pressurizing gas to force liquids through pipelines.
Pollution Control
Nitrogen can also be used for pollution control, notably for eliminating volatile organic compounds from liquids. It helps to remove harmful vapours and liquids from industrial equipment also.
Pharmaceuticals
Nitrogen is an essential part of almost every large scale class of medicines, including antibiotics. In its nitrous oxide form, nitrogen is used as a pharmaceutical anaesthetic agent.
