At the AIPT 2026 Conference in Milan, Alberto Arici presented the first experimental results on the characterization of aqueous ionic-liquid systems for CO₂ absorption, combining thermophysical property measurements with Taylor-bubble experiments.

The contribution investigated how the composition and thermophysical properties of ionic liquid–water mixtures affect bubble behaviour and gas–liquid mass transfer. Measurements of viscosity, density and surface tension were combined with Taylor-bubble experiments to characterize bubble dynamics and evaluate the liquid-side mass-transfer coefficient, providing experimental insight into the coupling between fluid properties, hydrodynamics and CO₂ transport in ionic-liquid-based absorption systems.
