What is Inerting? Gases Used for Inerting and Their Selection
网页Inerting refers to the process of introducing an inert gas into an enclosed space to release the gas already present, resulting in a kind of hazard. Although this process can be used to displace toxic gases, it is most commonly used to displace oxygen or to reduce the oxygen concentration in a space when the space is completely enclosed and substitution is not
