N2 - Solubility has an important influence on industrial applications of amine solvents. The CO2 equilibrium solubilities of EAE-1DMA2P solvents were obtained in 1:2, 1.5:1.5, and 2:1 ratios at 298–333 K and CO2 partial pressures of 8–100 kPa. Using these data, accurate prediction of CO2 equilibrium solubility of EAE-1DMA2P solvent was achieved by constructing activity coefficient model with an AARD of only 0.79%. In addition, by constructing the solubility prediction model of EAE-1DMA2P system based on empirical model, KE model, Austgen model, Li-Shen model, Hu-Chakma model, Helei Liu model, and Liu et al. model and the results were compared to confirm introduction of the activity coefficient has effectively improved the accuracy of the model prediction. Based on thermodynamic parameters of solubility, ΔrGm and ΔrHm, EAE-1DMA2P solvent was screened against other solvents. The results showed that EAE-1DMA2P solvent had excellent absorption, reaction rate and low desorption energy consumption, suggesting its potential in CO2 capture.
