Density and speed of sound measurements in MEA + CO2 and DEA + CO2

These datasets contain experimental measurements of density and speed of sound obtained in mixtures of monoethanolamine (MEA) + CO2 and diethanolamine (DEA) + CO2. Experimental results in binary mixtures were obtained for temperatures up to 393 K and pressure up to 70 MPa to support the updating of the fundamental equation EOS-CG. From these results two simplified formulations were developed and are available on Zenodo at 10.5281/zenodo.17209074
