To present vapor and liquid equation (VLE) of this system and predict  solubility, the ion specific non-electrolyte Wilson-NRF local composition model (isNWN) was used in this study; the framework of this model was molecular. Therefore, it was suitable for both electrolyte and non-electrolyte solutions. The present research employed the NWN model and the Pitzer-Debye-Hückel theory in order to assess the contribution of the excess Gibbs energy of electrolyte solutions in a short and long range. The data of  solubility in water and the system of aqueous  were correlated in the model considering a temperature range of  and a pressure range of and . The average absolute error of ( ) and ( ) systems were  and  respectively. The results and comparisons with other models proved that the experimental data were exactly correlated in the model.}, keywords = {CO2 capture,Solubility,Non-electrolyte Wilson-NRF,Thermodynamic Modeling,Potassium carbonate,Ion-specific Parameters}, url = {https://ijogst.put.ac.ir/article_94250.html}, eprint = {https://ijogst.put.ac.ir/article_94250_811c9d2763d2f9e1940c87c51f98af9d.pdf} }
