A facility designed for precise measurements of phase equilibria of CO2-rich mixtures relevant for CCS conditioning and transport is demonstrated. The setup aims for high accuracy in pressure, temperature, and composition measurements for pressures between 4 and 200bar and temperatures between -60 and 150°C.In this paper, the test measurement of the N2 / CO2 system in the vicinity of the critical point for CO2, have shown the ability to produce measurements with the high accuracy and repeatability in temperature, pressure and compositio
