In this study, the densities of carbonated aqueous solution of amines (ethanolamine, methylethanolamine, aminoethylethanolamine, and N-methyldiethanolamine with piperazine) in various concentration and CO 2 loadings were measured with temperatures ranging from 20°C to 60°C. The measured densities are in good agreement with those reported in the literature. The density experimental data were correlated with temperature and CO 2 loading. Additionally, in case of the monoethanolamine, amine concentration was included into the correlation.Furthermore, an obtained correlation for density prediction of carbonated monoethanoloamine solutions was compared with Jouyban-Acree model. The fitted models are able to predict the density of carbonated amine solutions with a satisfactory precision. Presented correlations can be used either to predict the density of carbonated amine solutions or to determine CO 2 loading of the investigated solution, if the density is known. The results of this paper may have an industrial application as a tool for process control of CO 2 capture systems.
