Comparison of equations-of-state with P-ρ-T experimental data of binary mixtures rich in CO2 under the conditions of pipeline transport

- Different EOS have been compared with experimental data of CO2-rich mixtures.
- LKP, PCFT and GERG showed the best prediction of CO2-mixture liquid density.
- EOS improvement has been performed by the binary interaction parameter regression.
- A simulation tool to determine CO2 transport pipeline conditions has been set up.
- Small impurity amount significantly affects the thermodynamic properties.
