The University of Alberta measured the solubilities of H/sub 2/S and CO/sub 2/ in 1.0, 2.0, and 4.28 kmol/m/sup 3/ aqueous solutions of methyldiethanolamine (MDEA) for temperature and acid-gas partial pressures ranging from 100/sup 0/ to 250/sup 0/F and 0.001 to 8600 kPa, respectively, used the procedure presented by Kent and Eisenberg to correlate the solubility data, and, calculated enthalpies of solution from the experimental results. Aqueous solutions of MDEA are attractive solvents for the selective removal of H/sub 2/S from process streams containing CO/sub 2/ and hydrocarbons.
