Which Gases Are Used Most Often for Industrial Work?
  • Opening Intro -

    The industrial world is incredibly diverse, with countless applications and processes that require the use of various gases.

    It’s essential for businesses in this sector to understand which gases are used most often for industrial work and why.


In this guide, we’ll explore some of the most popular industrial gases and their applications, ensuring you have the knowledge to make informed decisions for your operations.

Oxygen: Fueling Combustion Processes

Oxygen is one of the most widely used gases in industrial applications, primarily for its role in combustion processes. In these scenarios, oxygen is combined with a fuel source, such as natural gas or coal, to create a more efficient and cleaner combustion process. This gas is particularly well-suited to industries like metal fabrication, glass production, and waste treatment and is also used in medical and aerospace fields.

Nitrogen: A Versatile Inert Gas

A close second to oxygen in terms of industrial usage, nitrogen is an inert gas that serves a variety of purposes. It is commonly used for blanketing, which is a process in which the gas is pumped into a container or space to displace other gases like oxygen and prevent reactions that could cause degradation or combustion. This makes nitrogen an invaluable resource for industries where controlled atmospheres are critical, such as food and beverage, pharmaceuticals, and electronics.

Argon: A Protective Shield for Metals

Argon is another inert gas that offers a protective shield in industries where metal processing is common. One of the primary applications of argon is in welding processes, where it is used to shield the weld area from oxygen and nitrogen. This results in cleaner, stronger weld joints and reduces the risk of defects or corrosion. Additionally, businesses use argon in the production of metals like steel and aluminum, as well as in processes like sputtering for thin film deposition in electronics manufacturing.

Carbon Dioxide: From Cooling to Enhancing Plant Growth

Carbon dioxide (CO2) is a gas that finds widespread use across various industrial applications. One of its primary uses entails serving as a cooling agent, particularly in processes related to food preservation and refrigeration systems. In addition, CO2 can create a carbonated effect in beverages like soda and beer. Another interesting application of carbon dioxide is in the agricultural sector, where companies use it to enhance plant growth in greenhouses by increasing the concentration of CO2 in the air.

Gas Mixtures: Custom Solutions for Specific Applications

While the previous entries are good examples of gases used frequently for industrial work, an important thing to note is that a single gas may not suffice to meet specific requirements in certain industrial applications. This is where gas mixtures come into play, offering custom solutions tailored to distinct processes. These mixtures are composed of two or more pure gases combined in precise proportions to achieve an exact balance that caters to a particular industry’s needs, but there’s a lot more you should know about secondary reference gas mixtures.

To use welding as an example again, mixtures of argon, carbon dioxide, and other gases help further optimize the welding process, control the level of heat input, and ensure high-quality welds. The use of gas mixtures allows industries to enhance their performance, productivity, and safety levels by providing a highly customized solution for their specific needs.
