Inerting, Blanketing and Purging
Protect your products and installations
Do you want to create an inert atmosphere?
Do you want to prevent the creation of an atmosphere at risk of explosion within your manufacturing processes by avoiding the presence of oxygen?
Oxidation and microbial developments in your products limit their quality and conservation?
Inerting is a solution for protecting installations and products with an inert gas (Nitrogen, Argon) that is safe, effective and easy to implement.
Designed for Your Production
Guaranteed Safety Against The Risk of Explosion
Nitrogen breaks the “fire triangle”. When storing combustible materials, the risk of explosion appears as soon as the three elements are met: fuel, oxidiser (oxygen in the air) and a source of ignition. Avoid risk of explosion by removing Oxygen content in the protective atmosphere.
Quality Assured
Nitrogen protects products: pure, clean, perfectly dry and inert, Nitrogen protects a stored product and reduces any deterioration. In the absence of oxygen and humidity, the product is neither oxidised nor chemically altered; the powders do not agglomerate and the installations do not corrode.
Optimised Inerting
Continuous atmosphere regulation and control equipment developed by Air Liquide ensures automatic and permanent protection of installations and products. Maintain and precisely control the pressure of nitrogen as well as the oxygen content in the installation atmosphere. The injection of Nitrogen is manageable even in the event of a strong variation in flow.
Supply of Industrial or Food Grade Gases
Air Liquide offers all gas qualities and purities (N₂, Ar, CO₂) to meet the regulatory requirements of the various sectors of industry, either industrial grade gas or ISO 22000 certified food grade gas.
Our inerting solution for your air and humidity sensitive products.
Inerting consists of replacing a chemically explosive or reactive atmosphere, for example ambient air, with an inert gas or gas mixture to ensure that safety or quality is maintained . To make your inerting a success, Air Liquide supports you from the definition of the solution to its commissioning, in complete safety.
Examples of inerting gases
Inerting gases are intended for all stages of the production and transport of flammable or oxygen-sensitive products. Chemicals, fuels, cosmetic ingredients, food, medicines...: inerting takes place from the storage of raw materials to the packaging of the final product.
Most often, inerting with nitrogen (N₂) proves to be the best choice among neutral gases to reduce the oxygen concentration or replace the air in contact with your products.
An optimised introduction of neutral and inert gases requires expertise in the purge and sweeping techniques offered by Air Liquide.
Blanketing
Blanketing, also known as inerting, is the process of injecting an inert gas during steps in the storage, transport or production of products and at specific stages in the industrial process to eliminate oxygen or moisture present in atmospheric air. Because an inert gas does not interact directly with other compounds or materials, products are preserved and converted from a flammable or reactive condition into a safe, non-flammable and non-reactive state. Typical blanketing gases include nitrogen, argon and carbon dioxide.
Blanketing is critical to a wide range of industries such as refining, chemicals, pharmaceuticals, plastics, agriculture storage, as well as food and beverage.
Purging
Gas Purging is the process of removing the undesired medium from the system chamber, line, vessel or other area by replacing with an inert gas to create a safe condition and environment for processes that are sensitive to oxygen, moisture or other impurities medium, such as certain chemical reactions or the storage of reactive materials. Purging is often in used for during the startup or shutdown of processes to ensure that the system is safe for operation.
Nitrogen is often the preferred gas for processes such as inerting, purging, and blanketing due to its cost efficiency, straightforward production, and overall safety profile.
