A computer-operated static apparatus for the measurement of gas solubility data by the synthetic method was used for the experimental determination of hydrogen sulfide solubility data in aqueous N-methyldiethanolamine (MDEA), diethanolamine (DEA) solutions and aqueous solution of a mixture of MDEA/DEA. For these systems, measurements at 313 and 373 K and pressures up to about 1.3 MPa were performed. The experimental data from this work are presented in comparison to literature data. For the aqueous MDEA solution at 313 K, the solubility of H2S was compared to the solubility Of CO2 (C) 2004 Elsevier B.V. All rights reserved.
