Thermophysical Properties of CO2 and CO2-Rich Mixtures


Performer: National Institute of Standards & Technology

Project No: FE0003931


Accomplishments


  • Completed thermal conductivity measurements of pure CO2 at temperatures from 220 K to 752 K and pressures up to 69 MPa in the liquid, vapor, and supercritical gas phases with lower uncertainty than existing literature data in most of the region.
  • Measurements underway for dew point of H2O in compressed CO2 with four isotherms measured between 10 °C and 40 °C. Uncertainty is much smaller than existing literature data.
  • Completed evaluation of literature data for viscosity of pure CO2 and developed preliminary gas-phase correlation.
