Liquid Nitrogen is a compact and readily transported source of Nitrogen gas without pressurization. Further, its ability to maintain temperatures far below the freezing point of water makes it extremely useful in a wide range of applications and industries.

APPLICATION OF NITROGEN IN THE INDUSTRIES

  • Used for blanketing and purging applications to displace or dilute all unwanted gas or vapour
  • Widely used for reasons of safety and the prevention of product degradation in the chemicals and petroleum industry:
    • Inerting reactors and storage tanks
    • Purging vessels and pipelines
    • Sparging
    • Pressure-transfer of liquids
  • Shielding or assist gas for plasma-cutting aluminium and stainless steel, and as an assist gas for laser-cutting stainless steel TIG-welding of tough-pitch copper
  • Heat-treatment processes to protect some of the most reactive metals.
  • In electrochemical analysis, can be bubbled through to displace any Oxygen.
  • Pressure-transfer, where the movement of liquids or slurries from one piece of process plant to another is effected using gas pressure.
  • Tyre inflation: helps to extend tyre life and prevent tyre bursts.
  • Pressurising accumulators for batch-testing applications.
  • Can be used for shrink-fitting: the intense cold of liquid Nitrogen (-196°C), reduces the physical dimensions of a component placed in the liquid. Once cooled, the component is connected to a mating component before swelling to its original size as it reaches room temperature, thereby securing itself in place
