After careful comparison with the results of implanted PR-CPA EoS in Prosim software (Simulis™ Thermodynamics) with the presented data in the paper, the authors found that some parameters in the table "PR-CPA EoS parameters for compounds for association compounds considered in this work "and the table "BIP values and ARD of total pressure between PR-CPA EoS results and experimental data for acid gas-alkanolamine binary system" were misprinted. The average absolute deviations and results presented in the paper are not influenced by this misprint. Moreover, these parameters were also adjusted by Prosim using their algorithms. The correct and new parameter values are presented in Tables 1 and 2 respectively. Figure 1 shows a comparison between the calculations using the two set of parameters. We can easily observe that with new parameters, the prediction is improved.
