A new setup for accurate measurement of phase behavior of CO2-rich mixtures relevant for CCS has been designed, covering a range between - 60 and 150 °C in temperature and 0.4 and 20 MPa in pressure. In order to design safe and efficient infrastructure for CCS, the exact properties of these mixtures are required, and currently there are large knowledge gaps that need to be closed regarding the phase behavior. This paper reports a description of the experimental setup, how uncertainties will be verified and contained, and the very first test measurements performed using the setup.
