Transport of carbon dioxide is an essential feature of Carbon Capture and Storage. Power plants and industrial production plants - large point sources of CO2 - are often situated far away from storage locations, thus it is necessary to transport the resulting CO2-rich streams from the point of capture to the storage/utilization site. The CO2 quality required for transport may influence the choice of the capture technology and impose limits on the performance requirements. In order to design CO2 transport networks, it is important to have an accurate knowledge of the thermodynamic properties of CO2-rich mixtures containing small amounts of impurities. However, a suitable equation of state under the appropriate conditions for pipeline transport has not been clearly defined yet and different options may be used for different applications. For a quick evaluation of transport options, simple cubic EOS maybe sufficient, but for accurate measurements of CO2 flows needed for fiscal purposes more accurate non-analytical EOS may be required. In this paper the results of different EOS, including both cubic equations and non-analytical equations, have been compared with P-rho-T experimental data of binary mixtures of carbon dioxide with nitrogen, oxygen and argon obtained by the authors at the Energy and Environmental Laboratory of Piacenza (LEAP). Moreover a refitting of the mixture binary interaction parameters has been carried out for analyzed EOS. The Lee-Kesler-Plocker, the Perturbated-Chain SAFT equations and the GERG model showed good prediction of the density of CO2-mixtures in the conditions typical of pipeline transport: "dense" liquid phase (P above the critical pressure and T below the critical temperature) and CO2 molar concentration greater than 95%. Finally, the application of EOS to CO2 transport simulations and pipeline design has been performed in order to find the best configuration of pipelines on the basis of geometrical characteristics and operating conditions.
