Analysis of CO2 capture dynamics in aqueous amine solutions


Abstract : In the framework of reducing the greenhouse gas emissions, the CO2 capture technologies are in rapid development today. The gas–liquid absorption of CO2 by an aqueous amine solution in a packed column is one of the most advanced processes, in which the CO2 reacts with the amine, enhancing considerably the absorption rate. The amine choice is crucial for the process efficiency and many researches are currently devoted to the identification of new high-performance amines. An important issue of these researches is the accurate estimation of the physico-chemical properties determining the amine absorption performance. The TIPs Lab is developing since a few years ago an original experimental device based on the digital holographic Mach–Zehnder interferometry. This device enables the visualization of a gas-liquid mass absorption process, coupled with chemical reactions, when it is realized inside a Hele-Shaw cell. For instance, recently, relevant experimental data related to a new generation amine have been obtained using this device. This proposed PhD project has two goals: - The development of a modelling of the transport phenomena taking place in the device during the absorption of CO2 in aqueous amine solutions. - The development of a method enabling the estimation of physico-chemical properties determining the amine absorption performance, from the raw experimental results collected on the device. This method will be applied to new amines, in collaboration wit
