Supercritical Calorimetry: An Emerging Field
This paper explores supercritical calorimetry applied to the intrinsic properties of carbon dioxide in the liquid, gas and especially supercritical phase as well as applications and theory related to reaction calorimetry. The CO2sc heat capacity (cp) is measured over the range of 33–112 °C and 77–206 bar using a reaction calorimeter (RC1e, Mettler-Toledo) coupled with a high-pressure HP350 metallic reactor. Measured values are compared to theoretical values obtained from Wagner and Span's equation of state. 3D representations of the predicted values for heat capacity, density and sound speed of carbon dioxide in the fluid phase are presented.
