Sammendrag
A new facility for accurate measurement of viscosity and density of CO2-rich mixtures relevant for CO2 Capture and
Storage (CCS) has been constructed. The facility includes a two-capillary viscometer with several novel solutions to
enable high performance over a range between 213.15 K and 473.15 K (-60 and 200 °C) in temperature and up to 100
MPa (1000 bar) in pressure. There are currently very little data available on viscosity of liquid CO2-rich mixtures
relevant for CCS, needed for instance in simulations of injection processes and reservoirs. Integrated in the setup is
also a densimeter which is controlled to the same temperatures and pressures. Apart from providing density data, this
enables accurate conversion between kinematic and dynamic viscosity. The total uncertainty target of the facility is
0.1 % (95% confidence level), except close to the critical point.
