Gas-liquid contactors (GLCs) are one of the core technologies utilized in the chemical industry, which play a critical role for reactant conditioning, chemical conversion and separation processes. Within the scope of this project, we are developing a high-performance falling film reactors for CO2 capture via engineering the way CO2 in gas phase mixes with the liquid absorbent at the reactive gas-liquid interface (micro-mixing phenomena). The major impact of the study will be the performance increase at large scale, which would pave the way for the transition of CO2 capture technologies into practice.
