Continuously Measuring Temperature of Tube Walls

Borescope Increases Know-How for Air Liquide

A Case Study


Air Liquide’s steam methane reformers, producing hydrogen and carbon dioxide industrial gases, are critical assets and their operation, safety and reliability, are of paramount importance, however they are very challenging assets to maintain and operate.

Some of the common problems in reformer operation are burner, flue gas distribution and catalyst issues. All of these problems can directly affect Tube Wall Temperatures (TWT), tube life and lead to premature tube failure.

They can also lead a producer being overly cautious on TWT and losing valuable production every year.

Air Liquide is the world leader in gases, technologies and services for industry and health. It has implemented AMETEK Land’s Near Infrared Borescope (NIR-B) 3XR, an enhanced thermal imager, and now is gaining in know-how by continuously measuring temperature of tube walls within its steam methane reformers (SMR).
