Summary

The global temperature rise is rapidly approaching the critical IPCC-defined threshold of 1.5°C in just a few years; 2024 could be the first year to experience it.

One of the technological initiatives to mitigate this issue is the use of post-combustion carbon capture (PCC) gas-liquid absorption units in industries. PCC helps limiting carbon dioxide (CO2) emissions from industries related to fossil fuel burning.

Continuous monitoring and controlling of this chemical absorption process is essential for an efficient CO2 capture. The use of spectrometers to monitor the chemical changes of the CO2 capture solvent by employing mathematical algorithms is presented in this work.
