BUY LIQUID NITROGEN OR PURCHASE COMPRESSED NITROGEN GAS (N2)
Nitrogen is produced in large quantities at air separation plants which liquefy and subsequently distill air into nitrogen, oxygen and argon. If very high purity nitrogen is required the nitrogen produced may need to go through a secondary purification process. The lower range of Nitrogen purities can also be produced with membrane techniques, and medium to high purities with pressure swing adsorption (PSA) techniques.
Nitrogen is used for inerting finished medicinal products sensitive to degradation by Oxygen. Compressed Nitrogen is a preferred source for driving of surgical tools.
Cryogenic liquid nitrogen has a boiling point of -196° C Liquefied nitrogen is primarily used in the healthcare for:
Nitrogen is an odorless inert gas that is present in the air and necessary to balance the composition of air that we breathe. It is widely used in chemicals and pharmaceuticals processes, pigging and purging of pipelines, well stimulation, Enhanced Oil Recovery (EOR), injection and pressure testing, and as a packaging gas due to its inert nature. It is also used in packaged food stuff to preserve quality and enhance shelf-life.

Aircraft
Mostly used in the tyres to reduce the possibility of a blow-out along with reduced wear & tear during landing, take-off etc.
Automotive
Used in welding applications along with its use in the airbags.
Chemicals
Frequently used in the chemicals industry to transfer flammable chemicals, purging of line and blanketing of oxygen-sensitive products and materials.
Energy
Frequently used as blanketing or purging agent to pervert contamination in piping. Nitrogen can also provide protection for products to prevent contamination from air.
Food & Beverage
In liquid form nitrogen can cryogenically freeze or chill a variety of food items, from poultry to fish and from fruits to vegetable. Nitrogen based Individually Quick Frozen (IQF) has high demand and POL can offer complete solution for its customers. Nitrogen is also used to provide strength to the retail packaging and thus reduces overall costs.
Metal Production
Nitrogen perverts oxidation during steel making process by acting as carrier and purge gas. Nitrogen can be mixed with hydrogen or natural gas to provide oxygen free atmosphere for the heat treatment of various metals.
Oil and Gas
Nitrogen plays a huge part in the enhancement of oil & gas production. It does this via pressure maintenance, miscible displacement, immiscible displacement, gas assisted gravity drainage (GAGD), and mixed gas which improves reservoir reserves. Nitrogen can also be used in fracturing and improved operating efficiencies.
Pharmaceuticals
Nitrogen is frequently used in the pharmaceutical industry for purging of lines, mixture transfer via pressure and protection against moisture, oxidation or contamination of the various materials.
Refining
Nitrogen is used for blanketing of storage tanks, purging of pipelines, to remove Volatile Organic Compounds (VOC) from processes to reduce emissions.
Welding and Metal Fabrication
Used as purge gas, in plasma and laser based cutting applications.
