This work was a part of the joint industrial project (JIP) titled “Phase Behavior and Thermophysical Properties of Acid Gases and CCS Fluid Systems”. The project has been conducted jointly at Hydrates, Flow Assurance & Phase Equilibria Research Group, Institute of Geoenergy Engineering, Heriot-Watt University in Edinburgh, United Kingdom, and CTP, Centre Thermodynamique des Procédés, MINES ParisTech in Fontainebleau, France. At different phases of the project (Phase I: 2011–2014, Phase II: 2014–2017, Phase III: 2018–2021), various thermophysical properties, including phase equilibria, hydrates, solid formation, density, speed of sound, viscosity, interfacial tension, solubility in brine, and pH, have been investigated. The JIPs were supported by Chevron, GALP Energia, Linde AG Engineering Division, OMV, Petrobras, Petroleum Expert, Equinor, TOTAL, and National Grid Carbon Ltd., which is gratefully acknowledged. The participation of National Grid Carbon in the JIP was funded by the European Commission’s European Energy Programme for Recovery. The authors would also like to thank the members of the steering committee for their fruitful comments and discussions.

N2 - Density was measured for three multicomponent CO2 mixtures (with CO2 molar fractions of 0.406, 0.693, and 0.987) over a wide range of temperature 220–422 K and pressures up to 62 MPa. Measurements were performed using a vibrating tube density meter (VTD) and an isochoric cell. The VTD was calibrated and validated to obtain the densities for all of the mixtures at five isotherms at T > 323 K. Also, using the isochoric cell, density measurements were carried out for one of the mixtures at an extended range of temperature down to 220 K. The results from the VTD were utilized to calculate compressibility factor as well as second and third virial coefficients for all of the samples. For the reported properties, uncertainties associated with the measurements were calculated. Finally, the measured densities and calculated properties were compared against predictions of the GERG-equation of state (EoS).
