Definition - What does Inerting mean?

Inerting is the process in which a substance is converted from a reactive or flammable condition to a non-flammable, non-reactive or a safe state. It can be done by adding inert gas that replaces the atmospheric air containing moisture or oxygen. Inerting is capable of reducing the risk of explosion and also prevent dust explosions and unwanted reactions. The process is applicable to the enclosed plants as the plants which are substantially open to the atmosphere can never be effectively inerted because the oxygen concentrations which prevail are expected to vary.

Petropedia explains Inerting

Inerting is considered only when explosive or flammable hazards cannot be removed by other ways. It is used to reduce the probability of the combustion of explosive materials which are stored in a confined place by maintaining inert gas or a chemically non-reactive gas like nitrogen. Inert gases do not interact directly with the products or compounds. Nitrogen is usually used for inerting, but argon and carbon dioxide are also used at times. The main objectives of the process are to boost the safety and enhance the product quality. Various inerting processes are used such as purging, stirring, stripping, blanketing and sparging.
