New experimental results for the solubility of the single gases carbon dioxide and hydrogen sulfide in 8 m (i.e., 48.8 wt %) aqueous solutions of 2,2‘-methyliminodiethanol ( N -methyldiethanolamine; MDEA) at temperatures between 313 and 393 K and total pressures up to 7.6 MPa are reported. A thermodynamic model for describing such phase equilibria is revised and extended using the new data.
