Direct Air Capture (DAC) Testing With FTIR

4th November 2024

Removal of CO₂ from the atmosphere itself, rather than at the emission source, has been proposed as a technology to slow the rate of global temperature rises. Protea’s analysers are used to test this technology. Using Protea’s FTIR gas analyser, developers of Direct Air Capture (DAC) technology have been able to show the efficiency of removal of CO₂ from the atmosphere. By using a hybrid FTIR that can be used in a fixed cabinet but also removed for portable use, technologists have carried out testing across multiple sample locations within pilot plants.

The FTIR analyser is optimised to measure low range, 0-500ppm CO₂, so that ambient air and then CO₂-free air can be tested. Not only CO₂, but the benefit of FTIR is that other gases in ambient air such as CH₄ and N₂O can also be monitored. Installing the plants near to more highly polluting processes, even ambient NO_x can be measured through the process.
