Inert Gas Blanketing

What is it for?

The process in which inert gases such as nitrogen and argon are injected during production, storage or transportation of products or at any specific stage involved in the industrial processing to remove oxygen, moisture or other gases present in the atmospheric air is referred to as blanketing or inerting. 

In this process, products can be converted and preserved from a flammable or reactive state to a safe, non-flammable and non-reactive state. This is because an inert gas does not interact directly with other compounds or materials.

Requirement for Inert Gas Blanketing

In an industrial setup, the transferring of products is an important step. Nitrogen and Argon play a key role in preventing the oxidation around a space by neutralizing the atmospheric air. It helps to provide a protective around with no extreme reactions by preventing oxygen or any other atmospheric gas from coming into contact with any reactive product.



Air Liquide’s technical prowess and expertise in purging, blanketing and inert gas injection solutions help you manage these risks in various industries such as chemicals, refining, plastics, pharmaceuticals, agriculture, storage, food and beverage.

Gases used for Inert Gas Blanketing

Gas Applications: Inert Gas Blanketing

  • Inert Gas Blanketing (SPAL)

    SPAL from Air Liquide is a patented technological method to carry out inert blanketing processes. In this process, nitrogen is used to reduce interactions between atmospheric gases such as oxygen, water vapor or other gases and reactive chemicals. It can also be used to pressurize pipes for transferring products. Nitrogen plays a pivotal role in the entire process of inerting and blanketing to ensure safety and purity. SPAL reduces defects and rejections in steel and other industries and makes business easier for our clients. 

  • Inerting

    Inerting helps prevent the oxidation of substances by forming a protective layer of gas over them. This is done by either entirely or partially replacing the air around or on top of the substance with inert gas, preventing moisture or oxygen from coming in contact with a reactive or flammable substance. Nitrogen is the most commonly used gas for inerting. Through our FLOXAL supply system, we can produce nitrogen on-site. 

  • Blanketing

    Blanketing makes use of nitrogen and carbon dioxide for industrial processes. This helps safely store and preserve highly volatile substances by ensuring inert conditions are maintained for the desired substances. This process involves maintaining a protective layer of gas over the substance to prevent oxidation. Our leading technology offer includes Air Separation Units (ASUs). ASUs distil and liquefy air to separate it into nitrogen and argon, used in blanketing. Our VESTAL system is a customised solution designed to meet your nitrogen inerting and blanketing needs.
     

  • Sparging

    Sparging process involves separating oxygen from liquids such as beverages and oil and chemicals by passing finely dispersed gas bubbles through such liquid. Specifically for chemicals, this process is a quick and efficient way to increase a chemical reaction by increasing the surface area between phases. Inert gases such as nitrogen and argon are the most popular gases for reducing the oxidation of substances.

  • Turnarounds and Major Maintenance Support

    To meet turnaround requirements for significant industries and clients, Air Liquide provides a range of ARCAL™ welding gases, industrial nitrogen pumping and purge services, breathing air, bulk hydrocarbon gases, ALPHAGAZ™ pure gases and FLAMAL™ cutting gases. We also offer gas handling and distribution equipment to enable you to safely store, handle, and deliver these gases to your applications.
