An apparatus for the determination of the solubility of hydrogen sulphide, carbon dioxide and their mixtures in ethanolamine solutions at low pressures is described. With this apparatus, the solubility of H 2 S, CO 2 and their mixtures in aqueous solutions of monoethanolamine has been measured at partial pressures between 0.001 kPa and 9 kPa at temperatures of 80° and 100°C. The results for the mixture have been compared with two methods of prediction based on a thermodynamic model.
