All you need to know about Nitrogen Inerting

It is essential to ensure that the environment in the workplace has a mixture of gases with low oxygen levels to avoid the occurrence of spontaneous combustion. It may apply to any work environment, whether a manufacturing plant, a heat-treating facility, an offshore oil and gas platform, a chemical facility, an oilfield, or another mining business. The inerting process, also known as inertization, involves using inert nitrogen gas to restrict the quantity of oxygen that would otherwise produce a volatile combination. An application is developed to take advantage of the process to eliminate the oxygen content and maintain the explosion-proof state of the interted region.

Nitrogen Systems For The Process

Nitrogen is a standard gas used to replace an explosive mixture of dangerous gas that may explode when it combines with oxygen. Nitrogen is a fireproof, non-flammable gas injected into locations that must be shielded against the risk of explosions. Nitrogen, via the process of inertization, may displace oxygen in the surrounding air to such a degree that it prevents an eruption. Nitrogen, an inert gas that does not contribute to the combustion process, may be utilized risk-free to displace combustible liquids and explosive combinations. It is selected for its ability to remove oxygen and protect pipelines, tanks, systems, and facilities from corrosion.

What Kind Of Gas Is An Inert Gas?

Inert gases are non-combustible gases that do not react with the fuel and do not encourage combustion. These gases are also known as protective gases since they prevent combustion from occurring. During the process of inertization, the inert gas replaces the oxygen in the plant’s environment to such a degree that the potential for an explosive atmosphere is eliminated. Nitrogen is the typical choice for the role of the inert gas. The area that has to be safeguarded against explosions is then filled with the inert gas.

Precautions To Be Taken When Working With Inert Gases

During inertization, the MAOC should never be allowed to reach its maximum at any point. Appropriate safety ideas guarantee that the MAOC in the plant that has to be safeguarded (such as the centrifuge) is maintained during normal operation and during startup and shutdown. These preventative measures must go into action when specific triggers are met, such as when a specific alert level is reached. Because there is a risk of suffocation in inerted equipment, appropriate steps for personal safety must be implemented, including the following:

  • Taking precautions to ensure that the inert gas does not hurt a person’s health
  • If there is a potential for a leak or an overpressure operation outside of the plant, certain precautions must be followed.
  • In the case of severe leakage, precautionary precautions should be taken across the whole operation room.

Inertization Systems Often Find Use In The Following Application Areas:

  • The chemical and pharmaceutical manufacturing sectors
  • When operating in the mineral oil business with flammable organic solvents or hazardous volatile components.
  • To prevent oxidation during manufacturing goods used in the food and beverage sector and in edible oils.


The process of inertization is a method of explosion prevention that uses inert gas to stop the production of a combination that might explode. Inerting systems are put to use to protect vapours from escaping into the environment, which would result in pollution and air from entering the plant, resulting in oxidation. When working with compounds whose vapours might combine with oxygen in the air to produce a highly combustible combination, it is imperative to eliminate any potential for an explosion. In reality, an inert gas is used instead of the air.
