Abstract
The knowledge of physicochemical properties of a mixture of amine, water, and CO2 is beneficial in evaluating the postcombustion CO2 capture process and process equipment design. This study reviews the literature of density, viscosity, and surface tension measurements with the evaluated measurement uncertainties and proposed correlations for monoethanol amine (MEA), water, and CO2 mixtures. Adequate research has been performed to measure and develop correlations for pure MEA and aqueous MEA mixtures, but further studies are required for CO2-loaded aqueous MEA mixtures. The correlations fit measured properties with an acceptable accuracy, and they are recommended to use in process equipment design, mathematical modelling, and simulations of absorption and desorption.
Highlights
Knowledge of physical properties of solvents is important for chemical engineering work like process modelling and simulations, pilot plant operation, and the design of commercial plants [1]

Summary
Knowledge of physical properties of solvents is important for chemical engineering work like process modelling and simulations, pilot plant operation, and the design of commercial plants [1]. E measured physical properties of density, viscosity, surface tension, and thermal expansion coefficient of pure and aqueous MEA mixtures are available in the literature. For CO2-loaded aqueous MEA, most of the reported studies presented the viscosity of 30 mass% MEA solutions within the CO2loading range of 0–0.5 mol CO2/mol MEA. Idris et al [40] and Han et al [4] measured the surface tension of pure MEA and aqueous MEA at different temperatures using Rame-Hart advanced goniometer model 500.
