An inert gas does not interact directly with a compound or product. Nitrogen is the most commonly used gas for this purpose, but carbon dioxide or argon is sometimes used.
Objectives of inerting:
- Increase product quality
Boost safety
The different inerting processes are known as blanketing, purging, sparging, stirring and stripping.
