Densities (ρ), refractive indices (n D), speeds of sound (u), and surface tensions (σ) for the aqueous binary solutions of partially miscible 2-methyl-1-propanol, cyclopentanone, cyclohexanone, cyclohexanol, and ethyl acetoacetate were determined at the temperature of 298.15 K and atmospheric pressure over the mole fraction range reaching the solubility limit in the aqueous phase. Isentropic compressibilities, determined by means of the Laplace equation, have been calculated from the measured experimental data. To analyze the behavior of surface tensions, the extended Langmuir (EL) model was used.

“…Chemical absorption is an efficient procedure for the removal of acid compounds such as CO 2 , SO 2 , and H 2 S from sour gas streams. − The solutions containing alkanolamines are widely used for the absorption of acidic gases from natural gas and different refinery streams. − The well-known alkanolamines from this category are monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA) as effective chemical adsorbents. For the rational design of gas refinery, separation units, and the related chemical industries, information of the physicochemical properties of pure solvents and their mixtures such as surface tension and surface properties is necessary. − …”

Solutions containing alkanolamines or amines are broadly used for the removal of acidic compounds such as hydrogen sulfide (H2S) and carbon dioxide (CO2) from natural gas flows. In this study, the surface tension of three binary mixtures containing monoethanolamine (MEA) and alcohol (methanol, ethanol, or isopropanol) and three ternary systems containing MEA, water, and alcohol (methanol, ethanol, or isopropanol) were determined in the whole composition range at 303.15 K and ambient pressure by means of the Du Noüy ring method. From these data, the composition dependence of the surface tension (σ) and surface tension deviation (Δσ) of binary mixtures was correlated using the FLW equation (proposed by Fu et al.) and the MS equation (proposed by Myers and Scott), respectively. Then, the surface tension data of three ternary mixtures were correlated with a polynomial based on the Scatchard model. Also, the surface tension data of three ternary mixtures were predicted based on the FLW model. The results show a good agreement between the predicted and measured values, as well as the applicability of the FLW model in these ternary mixtures. Finally, the isoline curves of surface tension and surface tension deviation versus mole fraction of components for the ternary mixtures are plotted and discussed.
