Chemicals

Industrial gases play an important role in the chemical industry. Key applications include purging, inerting, maintenance, safety measures and environmental protection. Chemical processes and plant inerting are often critical to personal, material and plant safety.

Inerting is used to reduce and inhibit undesirable chemical reactions with oxygen, while purging involves the addition of a gas, usually nitrogen, to displace atmospheric gases with an inert atmosphere. Nitrogen purging involves introducing nitrogen into closed vessels, pipelines, or containers to remove hazardous atmospheres and clean the inner walls. During this process, nitrogen displaces oxygen and moisture, creating a stable, non-combustible environment.

 When purging, the most common gases used are nitrogen and carbon dioxide. Other inert gases may include helium or argon, depending on the application parameters. For most applications, pure, dry gaseous nitrogen offers the optimum combination of low reactivity with good economy. 

In many situations, inerting is the only way to meet safety standards during industry processes and maintenance. In other cases, inerting is used to maintain and improve product quality.
