Aeronautics:
Nitrogen is used for heat treatment, welding or laser cutting. Nitrogen-filled tires have an increased lifetime.
Automotive:
Nitrogen is used for heat treatment, welding or laser cutting. It also used to produce car pieces with gas assisted injection moulding process. Nitrogen-filled tires have an increased lifetime.
Chemicals:
Nitrogen is used directly in chemical process as carrier gas, fluidisation agent or for temperature control and catalyst preparation. It also takes part in several applications in a petrochemical site: for blanketing, drying, purging, stirring, etc.
Electronic components:
Nitrogen is used to provide an inert atmosphere, and is used for purging lines and chambers. Nitrogen is also used to carry / dilute materials into chambers. Nitrogen is used as a gas ballast for vacuum pumps.
Food:
Nitrogen is used to chill, freeze or control temperature of food products. It allows to control temperature during transportation and distribution with indirect liquid nitrogen injection. Nitrogen preserves and protects foods with Modified Atmosphere Packaging (MAP) to minimize oxidation, micro-organism growth or package collapse. It is also used to protect liquid foods from oxidation through inerting, pressure transfer and deoxigenation.
Glass
In glass production process, nitrogen is used to dilute the hydrogen in the reductive atmosphere needed over the tin bath.
Hospital care
Nitrogen is used in dermatology and for cryo-preservation.
Laboratories & Research Centres
Nitrogen is used to purge, dry or blanket analyzers or chemical reactors (under gaseous state or at low temperature liquid state). Nitrogen can also be used as a carrier gas in gas chromatography for various industrial and hospital analyses and quality control. It is also a balance gas of the calibration gas mixtures for environmental monitoring systems and industrial hygiene gas mixtures.
Metal fabrication
Nitrogen is used for heat treatment and laser cutting.
Metal
Nitrogen is used for inerting and stirring in many applications
Oil & Gas
For storage tanks and pipeline, nitrogen protects products and facilities (blanketing and inerting). It is also used in operations of snubbing/pigging, pipeline purging, cleanouts and leak test. For overbalanced drilling, nitrogen is used for gas lifting, fracking or fracturing.
Other
Nitrogen is used in heat treatment of various metals. It is a component of the mixtures used in carbon dioxide lasers. It is also used for pneumatic transportation of powdered flammable materials (charcoal).
Pharma & Biotech
Nitrogen is used for inerting, cryo-grinding, lyophilisation, drying, liquid phase transfer of products or synthesis intermediates. It is also used for cryo-condensation of waste gases and low temperature storage.
