CO2 removal from compressed air

CO2 is part of the air we breathe. Today ambient air contains CO2 concentrations of around 410ppm CO2.  

During the compression of air with a compressor, no CO2 is added but also no CO2 is removed. Therefore, compressed air automatically also contains CO2.

Similar to the air we breathe, CO2 is not harmful to the majority of compressed air applications.

Why do we need to remove CO2 from the compressed air?

CO2 in the compressed air isn’t harmful to the majority of the applications. Some applications however do require very dry and CO2-free air. In those applications, where both pollutants aren’t removed from the compressed air used, it can have serious consequences for the quality of the end product. Some examples are

  •  CO2 negatively influences the lifetime and quality of chemical raw materials for example used in lithium battery cells
  • In the industrial gas industry, when air is separated into the air gases nitrogen, oxygen and argon, CO2 freezes in the cold box of an air separation unit. This obstructs the separation of the air gases causing production losses and downtime. 
  • Instruments in the laboratory environment need purified air to be able to give reliable and constant measurement results. Moisture and CO2-free air can replace the more expensive lab gases used such as oxygen or nitrogen cylinders. 

How to remove CO2 from the air?

We offer dedicated CO2 removal units with a proven design similar to our desiccant air dryers design. CO2 removal units are filled with a zeolite specifically designed to remove CO2 below 10ppm or 1 ppm.

Our CO2 removal units are qualified for indoor and outdoor use and are made of carbon steel or stainless steel.
