摘要：
This work follows the thermodynamically modeling procedure to correlate the solubility of pure CO2 and H2S in [BMIM][MeSO4]. Moreover, solubility of acid gases mixture was predicted. The bubble point pressure calculation method was applied in which CPA EoS is responsible for fugacity coefficients calculation of the components. The CPA EoS combines SRK and Wertheim's association term to handle non-ideal behavior of the polar and associating components. The AADs% of H2S+IL and CO2+IL binary subsystems were calculated as 18.4 and 17.36 respectively. Moreover, AADs% equal to 27.26 and 6.74 were obtained for predicted partial pressures of CO2 and H2S, respectively.
