Inerting with inert gas - usually nitrogen (N2), but also carbon dioxide (CO2) and in special cases argon (Ar) - creates a controlled atmosphere that prevents explosions, deflagrations and fires by purging, blanketing or displacing. The displacement of oxygen in systems such as mixers, dryers or mills ensures that vapors or dusts do not ignite.
Nitrogen is the main gas used in industrial inertization. Depending on the temperature and the processes to be inerted, carbon dioxide can also be used in a few cases.
In many industrial processes, but especially in the
- chemical
- petrochemical
- pharmaceutical industry and in
- refineries,
it is necessary to
- rule out undesirable reactions
- avoid explosions
- prevent deflagrations
- Moisture protection of products
- Oxidation protection
