The solubilities of carbon dioxide in water (1) + monoethanolamine (2) + 2-amino-2-methyl-1-propanol (3) have been measured at 40, 60, 80, and 100 C and at partial pressures of carbon dioxide ranging from 1.0 to 200 kPa. The ternary mixtures studied were w[sub 2] = 0, w[sub 3] = 0.3; w[sub 2] = 0.06, w[sub 3] = 0.24; w[sub 2] = 0.12, w[sub 3] = 0.18; w[sub 2] = 0.18, w[sub 3] = 0.12; and w[sub 2] = 0.24, w[sub 3] = 0.06 where w is the mass fraction. The modified Kent and Eisenberg model has been used to represent the solubility of CO[sub 2] in the ternary solutions. The model reasonably reproduces the equilibrium partial pressure of CO[sub 2] above the ternary solutions, not only over a temperature range from 40 to 100 C, but also for various concentrations of components in the ternary solutions.
