Inerting, Blanketing & SpargingInert gas atmospheres to prevent unwanted reactions and keep your products pure as you made them

Nitrogen is used in blanketing, inerting, and sparging, to improve workplace safety and maintain product quality.

Inerting involves the addition of a gas (usually nitrogen) to displace atmospheric gases with an inert atmosphere. 

  • Inerting is usually done to exclude oxygen or moisture and prevent unwanted reactions which could reduce product purity and may result in dangerous reactions that may be catastrophic

  • In certain cases, carbon dioxide, argon, or less pure nitrogen gas from a generator may be more suitable than pure nitrogen

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.

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.
