摘要：

The solubilities of hydrogen sulfide in aqueous mixtures of monoethanolamine (MEA) with N-methyldiethanolamine (MDEA) have been measured at 40, 60, 80, and 100-degrees-C and at partial pressures of hydrogen sulfide ranging from 1.0 to 450 kPa. The mixtures of alkanolamines studied are 4.95 kmol m-3 MEA, 3.97 kmol m-3 MEA + 0.51 kmol m-3 MDEA, 2.0 kmol m-3 MEA + 1.54 kmol m-3 MDEA, and 2.57 kmol m-3 MDEA aqueous solutions. The solubilities of hydrogen sulfide in aqueous alkanolamine solutions are reported as functions of the partial pressure of hydrogen sulfide at the temperatures of 40-100-degrees-C.
