| Nitrogen is used in blanketing, purging, and sparging, to improve workplace safety and maintain product quality. More information on these processes:
Blanketing is the act of maintaining an inert atmosphere of nitrogen gas during storage and processing.
· Blanketing with nitrogen is safe and dependable in maintaining a constant protective layer of gas on top of a work substance.
· Humid air in the head space is replaced by high-purity, inert, and totally dry nitrogen. A precise valve-control system ensures that as the tank is filled or emptied, the nitrogen content automatically adjusts to maintain the protective blanket.
· Blanketing results in workplace safety, process reliability, and protection from food degradation through oxidation.
Purging involves the addition of a gas (usually nitrogen) to displace atmospheric gases with an inert atmosphere.
· Inerting is used to reduce the risk of explosions, prevent dust explosions, and inhibit undesirable reactions.
· Besides nitrogen, CO2 and argon are also used.
With Sparging, nitrogen is bubbled through or dissolved into an oil, to force out oxygen or any other gases dissolved in it—gases that can eventually replace the atmosphere above it and lead to product degradation or unsafe conditions.
· Sparging offers excellent control and does not introduce any other substance into the liquid.
· Sparging with nitrogen is fast and effective and can be easily introduced to the process environment.
