摘要

Physicochemical properties such as density and viscosity of solvents used for CO2 capture are determined to design the industrial equipment used in carbon dioxide absorption. Additionally, mathematical modelling of these properties is essential to predict their behaviour during operation. The Jouyban–Acree model, which directly correlates solution densities with composition, serves as an effective tool for predicting densities of solutions with known compositions or estimating unknown compositions from measured densities. It is applicable to both binary and ternary systems and accounts for temperature variations in the data. In the present work, the densities of aqueous solutions of DEEA (diethyl ethanolamine), MEA (mono ethanolamine) and DETA (diethylene triamine), along with the densities of the binary mixtures of DEEA + MEA and DEEA + DETA, obtained from the reported literature, were modelled using the Jouyban-Acree model for binary mixtures. Also, the densities of the ternary solutions DEEA + MEA + H2O and DEEA + DETA + H2O were modelled using the Jouyban–Acree model for ternary mixtures. The regressed parameters were further used to predict the densities of the studied binary/ternary systems within the temperature range 293–333 K. For most of the systems studied, the adjusted coefficients of determination were greater than 0.9, the absolute average relative deviations were below 0.5% and the absolute maximum deviations were below 10 kg·m−3. The Jouyban–Acree model was found to correlate the density data of the DEEA + MEA + H2O and DEEA + DETA + H2O systems with high precision.
