Inerting, also known as blanketing, is the process of replacing the atmospheric air around a substance or material with a non-reactive gas, such as nitrogen or argon, to ensure it stays in a passive or unreactive state.
Nitrogen is typically used due to its inertness and friendly environmental profile making it suitable for a host of applications. Since it does not react with most materials, nitrogen is an excellent inerting, blanketing and purging gas that can be used to protect valuable chemical products from harmful contaminants. One of its most important uses is to eliminate flammability risks in reactor vessels and storage tanks.
Other gases such as carbon dioxide and argon can also be used in some cases for inerting purposes.
We can help you choose the optimum method to meet your needs, while also keeping gas usage to a minimum.
