the solubility of co2 in the primary, secondary, tertiary and sterically hindered amine aqueous solutions at various conditions was studied. in the present work, the modified kent-eisenberg (m-ke), the extended debye-hückel (e-dh) and the pitzer models were employed to study the solubility of co2 in amine aqueous solutions. two explicit equations are presented to evaluate the concentration of h...

In this paper, the solubility of CO2 in AMP solution have been measured at temperature range of ( 293, 303 ,313,323) K.The amine concentration ranges studied are (2.0, 2.8, and 3.4) M. A solubility apparatus was used to measure the solubility of CO2 in AMP solution on samples of flue gases from Thermal and Central Power Plants of Esfahan Steel Company. The modified Kent Eisenberg model was used...

Modelling of CO2 solubility in aqueous solutions potassium lysinate (LysK) is mainly hindered by scarcity experimental vapor–liquid equilibrium data and lack chemical constants associated to the reaction mechanism for CO2/LysK/H2O system. Therefore, Kent-Eisenberg (KE) correlation stands out from literature, being among most used approaches description partial pressure at different loadings. In...

CO2 capture attracts significant research efforts in order to reduce the volume of greenhouse gases emitted from fossil fuels combustion. Among studied processes, chemical absorption represents a mature approach and, this direction, new solvents, alternatives monoethanolamine (MEA), have been suggested. In work, solubility aqueous solutions 2-amino-2-methyl-1-propanol (AMP) and 3-(methylamino)p...

Gas sweetening, the removal of acid gases (H2S and CO2) by absorption in aqueous alkanolamine solutions, is an important gas treatment operation. Methyldiethanolamine (MDEA) is widely employed for gas sweetening, because of its high absorption capacity and flexibility to meet process requirements. For process simulation or design, realistic predictions of acid gas solubilities in MDEA solutions...
