Compressed Nitrogen

Compressed Nitrogen

Pakistan Oxygen Limited (POL) offers a wide array of industrial and medical gases to support the full requirement of industry.

Nitrogen is produced by our Air Separation Units (ASU) where the process begins with a main air compressor that sends air through a clean-up system that removes moisture, carbon dioxide, and hydrocarbons. Later through liquefaction of atmospheric air, nitrogen is separated by continuous cryogenic distillation. The finished product is then stored as a cryogenic liquid in specialized vacuum insulated cryogenic containers and is transferred to customers as per their demand. Nitrogen can also be produced non cryogenically using pressure swing adsorption method.


In higher concentrations, Nitrogen is an asphyxiant gas. It is essentially colorless and odorless in nature.


  • Nitrogen is used for liquid chromatography-mass spectrometry.
  • Nitrogen is used in large quantities in the chemical industry for blanketing, purging and pressure transfer of flammable chemicals. High purity nitrogen is also used by the semiconductor industry as a purge or carrier gas and for blanketing equipment such as furnaces when not in production.
  • Nitrogen is used as a purge gas or transporter gas in various industries and applications for cleansing and removing contaminants
  • Nitrogen is utilized as zero gas for diagnostic instruments. It is normally utilized as a balance gas in blends. Blends with carbon dioxide for modified atmosphere packaging (MAP) of nourishment stuffs.
  • Nitrogen is used extensively, either pure or, more commonly, in a mixture with natural gas, to provide an oxygen free atmosphere during heat treatment of various metals.
  • Nitrogen is also used as a fire extinguishing gas in mines.
  • Tires are often filled with nitrogen to prevent them from losing pressure and for limiting the risk of blow-outs.
  • Nitrogen is utilized in liquid state to solidify a wide assortment of fragile food items, for example, cheeseburgers, strawberries, shrimps and so on. Nitrogen may likewise be utilized for cryogenic pounding of plastics, rubbers and other synthetic
  • Liquid nitrogen is used in the nuclear industry, for scientific research.
  • In the medical sector nitrogen has its uses for storing biological materials like tissue, cells etc. Nitrogen is used to store biological materials like tissue, cells etc. It is also used for surgery.
  • Liquid nitrogen is used in the area of superconductivity.
