Abstract
- In this study, the densities of carbonated aqueous solution of amines (ethanolamine, methylethanolamine, aminoethylethanolamine, and N‐methyldiethanolamine with piperazine) in various concentration and CO2 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 CO2 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 CO2 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 CO2 capture systems. [ABSTRACT FROM AUTHOR]
