WebINERTING . DEFINITION OF INERTING. OR (REASON FOR INERTING) It is the process of introduction of Inert gas into a tank with purpose of reducing its Oxygen content well below 8%. Inerting will keep vapour/air mixture outside the flammable range. INERTING OF LOADED TANKS W.R.T. FLAMMABILITY DIAGRAM WebInerting An ignitable mixture can be made oxygen deficient by introducing enough non-combustible (inert) gas to make the mixture non-ignitable. Purging A system containing air can be made safe by introducing enough non-combustible (inert) gas so that when flammable gas is introduced, an ignitable mixture cannot form.
The basic principle of inerting is to completely or partially replace air containing oxygen and flammable and/or toxic gases that often contain moisture or inert gases. Inerting is based on the principle that a combustible (or combustible) gas can only burn (explode) when mixed with air in the correct … See more There are many chemical processes where inerting is required 1. to make the system or process explosion-proof 2. to eliminate … See more The most widely used gases for inerting are Nitrogen and Carbon dioxide.
