Equilibria of H2S and CO2 in triethanolamine solutions

Abstract The equilibrium solubility of H 2 S and CO 2 has been measured in 2.0, 3.5 and 5.0 mol/L triethanolamine solutions. Data were obtained at temperatures of 25°, 50°, 75°, 100° and 125°C at partial pressures of the acid gases ranging from 0.01 to 6360 kPa. Enthalpies of solution were calculated from the solubility data.
