Nitrogen

Nitrogen (N2) makes up the major portion of the earth’s atmosphere, accounting for 78.08% of total volume. It is a colourless, odourless, tasteless, non-toxic and almost totally inert gas in the gaseous and liquid form. It can be an asphyxiant in high concentrations. Nitrogen is produced in high volumes at our air separation plant.

One of the main applications of nitrogen is blanketing, purging and sparging in the food and chemical industries. It can also be found in modified atmosphere packages (MAP) for foodstuffs. In liquid form, it is an agent to shock-freeze food, store biological material, perform cryosurgery and cryogenically grind plastics and rubbers, for instance. Nitrogen is also widely used in the semiconductor industry, electronics and laboratory.

We provide nitrogen in both liquid and gaseous form. The nitrogen gas is delivered by 40L, 50L cylinders and pallets or refilled in the refilling station in the factory. The liquid nitrogen is distributed by LGC, ISO tank or pumped directly at the factory.

What is Nitrogen gas?

  • Industrial nitrogen gas has many applications in daily life as well as in production. Industrial nitrogen is widely used in many industries such as: fresh food preservation, stainless steel production, etc.
  • Nitrogen (from the root “Nito”) is a chemical element in the periodic table of elements with the symbol N. The atomic number is 7, the atomic mass is 14. Under normal conditions it is a colorless gas. , odorless, tasteless.
  • Nitrogen is quite inert and exists in the form of N2 molecules, also known as gaseous nitrogen. Nitrogen makes up about 78% of the Earth’s atmosphere and is a component of all living organisms. Nitrogen forms many important compounds such as amino acids, ammonia, nitric acid and cyanides. Extremely strong chemical bonds between nitrogen atoms make it difficult for both organisms and industry to convert nitrogen
  • Supplying industrial nitrogen gas 2 into useful chemical compounds. But at the same time, it also releases a large amount of useful energy when it burns, explodes or decomposes back into nitrogen gas. The synthesized ammonia and nitrates are the main industrial fertilizers. Nitrate fertilizers are the main pollutants that cause eutrophication in aquatic environments.

Nitrogen gas properties

  • It is a colorless, odorless, tasteless gas, slightly lighter than air (d = 28/29).
  • Nitrogen is slightly soluble in water, liquefies (-196oC) and solidifies at very low temperatures.
  • Do not sustain combustion and respiration.
  • At room temperature, nitrogen is chemically inert because of its stable triple bond.
  • At high temperatures nitrogen becomes active.
  • Nitrogen exhibits both oxidizing and reducing properties. However, oxidation is still predominant.

Application of Nitrogen gas in industry

Gaseous nitrogen

Produced rapidly by heating liquid nitrogen (see below) and evaporating. It has many applications, including serving as a more inert alternative to air. When oxidation is undesirable.
  • To preserve the freshness of packaged or bulk foods. By slowing down rancidity and other types of damage caused by oxidation
  • Manufactures electronic components such as transistors, diodes, and integrated circuits (ICs).
  • Stainless steel production
  • Inflatable automobile and aircraft tires due to its inertness and lack of moist, oxidizing properties, in contrast to air

Liquid nitrogen

Produced on an industrial scale in large quantities by fractional distillation of liquid air. It is often referred to by the pseudo-LN2 formula. It is a refrigerant (extreme cold). Can immediately harden living tissue upon contact with it.
 
When properly isolated from ambient heat, it serves as a thickener. And the transport source of gaseous nitrogen without compression. In addition, its ability to maintain temperature is sublime. Because it evaporates at 77 K (-196°C or -320°F) makes it extremely useful in many different applications. Examples in the role of an open cycle refrigerant include:
  • Refrigeration for transporting food
  • Preservation of organs as well as sperm and egg cells, samples and biological products.
  • In the study of refrigerants
  • In dermatology to remove ugly malignant skin lesions. Eliminates potential carcinogens, e.g. warts, calluses on the skin, etc.
  • Liquid nitrogen can be used as a cooling source to speed up CPUs, GPUs, or other types of hardware.
  • Liquid nitrogen is nitrogen in a liquid state, its temperature is very low, about -196 degrees Celsius. At this temperature, you also know it can destroy everything related to living organisms.
