The CO2/HCs fluids are widely discussed in the engineering and scientific studies. The viscosity, as one of the most important transport properties, plays a key role in the applications of CO2/HCs mixtures in different fields. The theoretical approaches are effective to supplement the experimental viscosity data in wide thermodynamic ranges. In this paper, viscosity models are built for CO2/HCs binary mixtures based on the Vesovic-Wakeham theory. The viscosity correlations and the potential parameters of pure species are selected from literature and utilized in the constructions of models. The viscosities of five industrially important CO2/HCs binary systems are predicted in the temperature range from 273.15 K to 973.15 K and at the pressure up to 200 MPa. The studied systems are CO2/CH4,CO2/C2H6,CO2/C3H8,CO2/n-C4H10 and CO2/iso-C4H10. The calculated values are compared with a large amount of experimental viscosity data over a wide temperature-pressure range. The extensive analysis shows that the calculated viscosity values of the present work could be used with confidence in different industrial applications.
