Accurate measurements of CO₂ rich mixture phase equilibria relevant for CCS transport and conditioning

This paper describes the experimental rig that has been constructed for the measurements of phase equilibrium of CO₂-rich mixtures under relevant conditions for CCS transport and conditioning. The rig is believed to have an accuracy better than 10 mK in temperature and 0.10% in pressure. Measurements will be performed using the analytical technique, which means that composition of all phases will be measured. In the years to come, a comprehensive experimental plan will be executed, resulting in new and accurate phase equilibrium data relevant for CCS conditioning and transport.
