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

摘要

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.
