Technical literature is prolific in reporting experimental data of properties such as activity and fugacity coefficients, as well as of other physicochemical parameters.
The authors determined activity and fugacity coefficients for the components of both mixtures.
They considered moderate and high pressure levels, and reported activity and fugacity coefficients of each component in the mixtures through Lewis rule and Redlich-Kwong state equation for carbon dioxide in vapor phase.
