For the design of acid gas treating processes, vapor-liquid equilibrium (VLE) data must be available of the solvents to be applied. In this study the vapor pressures of seven frequently industrially used alkanolamines (diethanolamine, N-methylethanolamine, N,N-dimethylethanolamine, N,N-diethylethanolamine, diisopropanol-amine, 2-(2-aminoethoxy)ethanol, 2-amino-2-methyl-1-propanol) were measured in an ebulliometer. The VLE experiments were carried out at presssures between (1 and 400) kPa and at a maximum temperature of 453 K. The experimental data can be used to improve the thermodynamic models in gas treating processes and to determine the amine losses in the absorber and desorber.
