Protection with inert gas  [ Return towards  Applications  ]

• Avoid constitution of explosive atmospheres during storage, transfer, treatment and conditioning of your flammable products?
• Secure your facilities (reactors, spin-dryers, silos…)?
• Protect your fragile products against oxidization and humidity?

Nitrogen is the inert gas generally used for such applications. Carbon dioxide can be interesting for operations of fire extinction and in cases where acidic properties of this gas are more especially requested.

Safety

When you store flammable products, the risk of explosion releases as soon as the meeting of three elements occurs:

presence of flammable steams or dusts (fuels)
presence of oxygen from the air (comburant)
source of ignition (generally, static electricity, hardly controllable)

Nitrogen injection in gaseous atmosphere on top of a container replaces the air and decreases the oxygen concentration, avoiding explosion risks. Air Liquide proposes equipment to automatically protect your installation.

Quality

Pure, clean, perfectly dry and inert, nitrogen protects your products:

No oxygen: your product doesn't oxidize
No humidity: your product doesn't chemically alter itself and powders do not agglomerate
No pollutant (absence of oil trace, very high pressure therefore there is no risk of backflow pollution): your product remains steady
Reduction of the microbial development risk (aerobe) nitrogen protects your products.

The use of nitrogen or all other inert gas prevents risk of anoxia, even poisoning risks in the case of C02. Therefore, our experts may offer gas safety training to your teams.
