Information on acid gas solubility in solvents utilized is needed for the design of gas plants. A mathematical model for the prediction of equilibrium solubility of CO2and H2S in aqueous 2-amino-2-methyl-l-propanol (AMP) solutions is presented. The equilibrium constant, Kltgoverning the main amine reaction is expressed as a function of not only temperature but also acid gas partial nressure and AMP concentration. Model oredictions agree favourablv with exnerimental data.
