Data on CO2 solubility in aqueous amine solutions are crucial for designing efficient CO2 absorption processes. This review provides a comprehensive discussion of the experimental methodologies used for measuring CO2 solubility in aqueous amine systems. Initially, the variations of the equilibrium cells, the main component in every experimental setup used for phase equilibrium measurements, appeared in literature studies, are discussed. The experimental methods are categorized, first, based on the synthetic or analytical approach for the determination of phases’ compositions (synthetic and analytical methods) and, second, based on the presence or not of a flowing phase (static and flow systems), respectively. In every case, the main advantages and disadvantages are discussed.
