Are you paying too much for nitrogen deliveries?
Do you order bulk N2? Looking for a more cost-effective and reliable option? Don’t buy nitrogen—make it onsite with a highly efficient Atlas Copco nitrogen generator!
What is nitrogen gas?
Nitrogen gas is an industrial gas produced using air separation by mechanical means by taking atmospheric air (the air that you are breathing — 78% nitrogen & 20.9% oxygen), pressurising it in an air compressor, and then separating it with either a membrane or PSA (pressure swing adsorption) generator.
Nitrogen can be supplied in multiple ways:
- Buying high pressure nitrogen cylinders
- Buying dewars of liquid nitrogen
- Buying bulk liquid nitrogen
Shifting to onsite nitrogen generation capabilities is just one way that manufacturing facilities can achieve significant cost savings, with the added benefit of a lower-carbon footprint to help lead the way as an environmental steward in the community.
What are the applications of nitrogen gas?
Nitrogen Gas Generation has a wide variety of applications, including:
- Serving as an inert replacement for air where oxidation is undesirable
- To preserve the freshness of packaged or bulk foods (by delaying rancidity & other forms of oxidative damage)—potato chips, nuts, snack foods & packaged salads
- To preserve the freshness of wine (by delaying rancidity & other forms of oxidative damage)
- On top of liquid explosives as a safety measure—paints & solvents
- The production of electronic parts such as transistors, diodes & integrated circuits (prevents oxygen & moisture)
- Dried & pressurised, as a dielectric gas for high voltage equipment
Selecting the right solution for your industry’s needs:
- Tyre filling — N2 eliminates oxidation (which causes premature tyre wear) & offers better tyre pressure retention
- Food industry nitrogen is an efficient, cost-effective way to displace oxygen & moisture
- Beverage N2 is used for beverage storage, CO2 mixing & beverage transport/dispensing (also for example to prevent oxidation of vitamin C in fruit juices)
- Packaging N2 prevents spoilage, preserves freshness, maintains flavour & dramatically extends shelf life
- Laser cutting — instead of air now we use nitrogen to cool down the metal sheets (because oxygen in the air causes decolouring of the cut edges). Nitrogen is also flushed over the laser mirrors to keep them clean from particles & humidity (what would disturb the laser beam)
- Drilling nitrogen displaces oxygen. It reduces the contamination of the hydrocarbon field. It prevents downhole fires & explosions, & is easily separated from the hydrocarbons
- Sintering nitrogen is used to inert the sintering process (sintering is the process of melting & compressing metal in moulds
- Refineries nitrogen is used to inert storage or process tanks as well as move product through pipelines at refineries
- Printing — high-speed printers uses nitrogen for drying & to prevent oxygen contamination on film production & separation
- Pipelines nitrogen is used to displace oxygen, slow down oxidation, break the ‘fire triangle’ & prevent explosions. It is also used to inert & also dry the pipelines
- Pharmaceutical industry #8212; most pharmaceutical companies have multiple nitrogen uses & purity demands
- Laboratory high-purity nitrogen is used as a carrier gas. But it is also used for chemical analysis, spectrometers & thermal analysers
- Gas assist injection molding — in plastic injection moulding nitrogen is often used as gas that prevents oxidation of the plastic & leaves the mould with a clean surface & without any sink marks
- Brazing is a process that is well matched for PSA generated N2. Nitrogen provides a blanket over the product that prevents decolourisation & oxidation
- Surface equipment inerting — by applying a cover of nitrogen, explosions in the environment can be prevented
- Blanketing prevents liquid from vapourising into the atmosphere, reduces ignition potential, prevents oxidation or contamination of the product by reducing its exposure to atmospheric air, it reduces the moisture content
- Fire suppression — reducing N2 in working areas or building has now been examined as a real solution to reducing the risk of combustion
- Fitness N2 is being used for gyms & sports science as a way to train by simulation altitude.
