CO2TablesSci Excel Add-In - Sample calculations in Excel
For thermodynamic properties the library uses new equation of state for carbon dioxide, formulated in Helmholtz energy. It is intended to be used for scientific applications that require maximum accuracy. Equation of state was presented in:
- "A New Equation of State for Carbon Dioxide Covering the Fluid Region from the Triple-Point to 1100 K at Pressures up to 800 MPa" by R. Span and W. Wagner, J. Phys. Chem. Ref. Data, Vol. 25, No 6, 1996.
It is the most accurate formulation for thermodynamic properties of carbon dioxide available today. In the formulation the authors paid special attention on the description of the critical region and the extrapolation behavior of the formulation. The CO2TablesSci Excel Add-In has been extrapolated to cover high temperature region up to 1773.15 K and pressures up to 1000 MPa, to meet the requirements of the most demanding high temperature supercritical CO2 applications.
For transport properties the library uses equations presented in:
- "The Viscosity of Carbon Dioxide" by A. Fenghour, W. A. Wakeham and V. Vesovic, J. Phys. Chem. Ref. Data, Vol. 27, No 1, 1998
- "A Reference Multiparameter Thermal Conductivity Equation for Carbon Dioxide with an Optimized Functional Form" by G. Scalabrin, P. Marchi, and F. Finezzo and R. Span, J. Phys. Chem. Ref. Data, Vol. 35, No 4, 2006
Operating system Vista / Windows 7 / Windows 8 / Windows 8.1 / Windows 10.
Excel 2007 / 2010 (32 bit & 64 bit) / 2013 (32 bit & 64 bit) / 2016 (32 bit & 64 bit) / 2019 (32 bit & 64 bit).
Installation and use of the library requires standard user privileges or better.

Range of Validity
The entire set of equations used by the CO2TablesSci Excel Add-In library, is defined by the following temperature and pressure range:
- 190 K < = T < = 1773.15 K
- 0 < p < = 1000 MPa
The reference state is set at:
- Reference temperature: T0 = 298.15 K
- Reference pressure: p0 = 0.101325 MPa
- Reference enthalpy in the ideal gas state at T0: h°0 = 0 kJ/kg
- Reference entropy in the ideal gas state at T0, p0: s°0 = 0 kJ/(kg·K)
