Industrial gases are elemental substances in gaseous form that find applications across a spectrum of industries, ranging from manufacturing and healthcare to electronics and metallurgy. These gases are often produced in large quantities through specialized manufacturing processes to meet the stringent purity and quality requirements demanded by various applications.

Methods of Industrial Gas Production:

1. Cryogenic Distillation:

A prevalent method for producing industrial gases is cryogenic distillation. This process involves cooling air or other feed gases to extremely low temperatures, causing them to liquefy. The different components of the liquefied gas can then be separated through distillation, resulting in high-purity industrial gases like oxygen, nitrogen, and argon.

2. Pressure Swing Adsorption (PSA):

Pressure Swing Adsorption is another common technique used for gas separation. In this method, gases are passed through adsorbent materials under varying pressure conditions. The adsorbent selectively captures certain gases while allowing others to pass through, enabling the production of gases such as hydrogen and nitrogen.

3. Chemical Reactions:

Certain industrial gases are generated through chemical reactions. For example, the production of ammonia involves reacting nitrogen and hydrogen under specific conditions. This method allows for the synthesis of gases with specific properties required for various applications.
