Data are presented for the solubility of methane and of ethane in a 3 kmol/m{sup 3} (34.7 mass %) solution of methyldiethanolamine. Temperatures in this study ranged from 25 to 130 C and pressures to 13 MPa. The data were incorporated into a rigorous thermodynamic model that has been applied to other similar systems. The model is a combined Raoult`s law-Henry`s law approach. The solubilities in the alkanolamine solution are correlated in terms of the salting-in ratio, the ratio of the mole fraction solubility in the amine solution to that in pure water.
