Investigation of Interfacial Tensions for Carbon Dioxide Aqueous Solutions by Perturbed-Chain Statistical Associating Fluid Theory Combined with Density-Gradient Theory

The phase equilibira and surface tensions of N-methyldiethanolamine (MDEA), diethanolamine (DEA) and their aqueous solutions were investigated by using the perturbed-chain statistical associating fluid theory (PC-SAFT) and density-gradient theory (DGT). The molecular parameters and influence parameter were respectively regressed by fitting to the experimental data of phase equilibria and surface tensions of pure fluids. With the molecular parameters and influence parameter as input, the surface tensions of MDEA, DEA and their aqueous solutions were correlated satisfactorily.

Density Gradient Theory

The perturbed-chain statistical associating fluid theory (PC-SAFT) and density-gradient theory (DGT) were used to construct an equation of state (EOS) for the bulk and interfacial properties of monoethanolamine (MEA) and its aqueous solutions. The molecular parameters and influence parameter were regressed by fitting the experimental data of phase equilibria and surface tensions. With the molecular parameters and influence parameter as input, the surface tensions of MEA aqueous solutions were correlated satisfactorily.
