Calculation of gas solubility in aqueous solutions of 2-amino-2-methyl-1-propanol for CO2 capture
Due to the global warming, absorption processes with aqueous alkanolamine solutions are widely used to absorb gases such as H2S and CO2 in many industrial areas as petrochemical, natural gas and power plants. Calculation and prediction of phase equilibrium in such kinds of systems is very complex because of chemical reactions available with vapor-liquid equilibrium. In this paper, the Clegg-Pitzer equation is used for the calculation of activity coefficients of components in the aqueous phase, and Peng-Robinson equation of state is used for the calculation of fugacity coefficients of components in the vapor phase. The 2-amino-2-methyl-1-propanol (AMP) is tested as the absorption solvent. The results are given for a wide range of temperature as 25 ~ 100 and ℃a wide range of CO2 partial pressure as 0.1 ~ 1000 kPa. The thermodynamic models and the calculation procedure can be used in simulation of absorption processes for CO2 capture.
