The absorption-adsorption hybrid method has potential superiority on CO2 separation and caption. In this work
the Patel-Teja equation of state coupled with the Kurihara mixing rule was used to describe the absorption equilibrium. The binary interaction coefficients between pure gas components and glycol were determined by correlating the experimental gas solubility data. Then
the Langmuir equation was applied to calculate the adsorption of gas in ZIF-8
and get the correlation of osmotic pressure of glycol liquid membrane on the surface of ZIF-8 with the equilibrium fugacity of gas component. Finally
the obtained model was applied to predict the separation of CO2 from gas mixture using ZIF-8/glycol slurry.
