Densities in liquid solutions of monoethanolamine (MEA) and water have been measured at temperatures from (298.15 to 423.15) K. The mass fraction of MEA ranged from 0.3 to 1.0. Excess volumes were correlated by a Redlich-Kister equation. The model uses a third-order Redlich-Kister equation and a linear relationship with the temperature. Densities of CO2 loaded aqueous MEA solutions were measured at temperatures from (298.15 to 413.15) K. The mass fraction of MEA was 0.3, 0.4, 0.5, and 0.6. Molar volumes of CO2 loaded aqueous MEA solutions were correlated by the equations from the literature. Polynomial equations are in turn used to correlate the parameters with the temperature. Surface tensions of aqueous MEA solutions were measured at temperatures from (303.15 to 333.15) K. The mass fraction of MEA ranged from 0 to 1.0. The experimental surface tension data were correlated with temperature and mole fraction, respectively.
