Dana Al Ghoul: Improving CO2 Capture

Innovation, Research Sustainable Energy

The Unité Chimie et Procédés (UCP), one of ENSTA’s laboratories, devotes a significant portion of its work to decarbonization through CO2 capture and utilization. Improving one of the CO2 capture processes is precisely the subject of the thesis by Dana Al Ghoul, a PhD student at the UCP, to whom Energy4Climate—the interdisciplinary center at the Institut Polytechnique de Paris focused on the energy transition—has dedicated a video.

Amines, organic compounds derived from ammonia, have the unique property of easily binding to CO2, which allows for highly efficient capture even in flue gases where its concentration is low.

But once the CO2 is captured, the amine solution must be heated to release the CO2 in a controlled manner so it can be stored or used in chemical or industrial applications. The only difficulty is that the release temperature is 120°C, which is energy-intensive and has so far limited the appeal of the process.

Is it possible to lower this temperature? That is the focus of Dana Al Ghoul’s thesis work presented in this video.
