This report summarizes the results of work performed under DOE/NETL Interagency Agreement DE- FE0003931, which began in October 2011 and ended (after a 6-month no-cost extension) March 31, 2015. The key objectives for this work were to: (1) Measure the dew point of water in compressed carbon dioxide (CO2) at temperatures relevant for pipeline transport. (2) Use the measured data to optimize a mixture thermodynamic model for the H2O/CO2 system. (3) Produce a new, reference-quality correlation for the viscosity of pure CO2. (4) Measure the thermal conductivity of carbon dioxide over a wide range of conditions. (5) Produce a new, reference-quality correlation for the thermal conductivity of pure CO2.
