NGP Installation in Sydney.
Tyre filling N2 eliminates oxidation (which causes premature tyre wear) and offers better tyre pressure retention.
Food Industry Nitrogen is an efficient, cost-effective way to displace oxygen and moisture.
Beverage N2 is used for beverage storage, CO2 mixing and beverage transport/dispensing (also for example to prevent oxidation of vitamin C in fruit juices)
Packaging N2 prevents spoilage, preserves freshness, maintains flavour and 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 and humidity (what would disturb the laser beam).
Drilling Nitrogen displaces oxygen. It reduces the contamination of the hydrocarbon field. It prevents downhole fires and explosions and is easily separated from the hydrocarbons.
Sintering Nitrogen is used to inert the sintering process. (Sintering is the process of melting and compressing metal in molds). Oxygen (which causes corrosion) is removed from the environment by introducing nitrogen into the process.
Refineries Nitrogen is used to inert storage or process tanks as well as move product through pipelines at refineries. The purpose of nitrogen is to prevent hazardous or explosive environments, or because of the adverse effect oxygen has on certain chemicals.
Printing High-speed printers uses nitrogen for drying and to prevent oxygen contamination on film production and separation.
Pipelines Nitrogen is used to displace oxygen, slow down oxidation, break the “fire triangle,” and prevent explosions. It is also used to inert and also dry the pipelines (because as an extra value-added features N2 is very dry!)
Pharmaceutical Industry Most pharmaceutical companies have multiple nitrogen uses and purity demands. Lab GCs and some other low-flow processes require very low flow at very high purity (99.999%-99.9995%), while the LCMS requires only about 99%-99.9%. Labs may also need small volumes of liquid N2 for freezing. The balance of most pharmaceutical applications are blanketing, inerting and sparging (99%-99.9%).
Laboratory High-purity nitrogen is used as a carrier gas. (For example gas chromatography instruments) But it is also used for chemical analysis, spectrometers and thermal analyzers.
Gas assist injection molding In plastic injection molding nitrogen is often used as gas that prevents oxidation of the plastic and leaves the mold with a clean surface and without any sink marks. Nitrogen is also injected together with the plastic creating air channels which results in less plastic material needed without loosing its strength.
Brazing Brazing is a process that is well matched for PSA generated N2. Nitrogen provides a blanket over the product that prevents decolourization and oxidation. At 99.9% purity, some decolourization occurs, but there is still very little oxidation and no structural impact on the braze itself.
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 • Reduces the moisture content
Fire Suppression: Reducing N2 in working areas or building is now been examined as a real solution to reducing the risk of combustion
FITNESS: N2 is being used for gyms and sports science as a way to train by simulation altitude.
