Solubility of Single Gases Carbon Dioxide and Hydrogen Sulfide in Aqueous Solutions of <i>N</i>-Methyldiethanolamine at Temperatures from 313 to 393 K and Pressures up to 7.6 MPa: New Experimental Data and Model Extension

Abstract

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.
