Abstract: In this work, the physical solubility of N2O in (monoethanolamine + water), (N-methyldiethanolamine + monoethanolamine + water), and (2-amino-2-methyl-1-propanol + monoethanolamine + water) and the diffusivity of N2O in (N-methyldiethanolamine + monoethanolamine + water) and (2-amino-2-methyl- 1-propanol + monoethanolamine + water) have been measured at (293, 298, 303, 308, and 313) K. For the binary mixture, the amine concentration ranges studied are (2.0, 2.5, and 3.0) kmolâm-3. For the ternary mixtures, the total amine strength in the solution was kept at 30 mass %, in view of the recent interest in using concentrated amine solutions in gas treatment. A solubility apparatus was used to measure the solubility of N2O in amine solutions. The diffusivity was measured with a wetted wall column absorber. The accuracy of the measurement is estimated to be (2%. A semiempirical model of the excess Henry’s constant was used to correlate the solubility of N2O in amine solutions. The para...
