![]() The density of supercritical carbon dioxide is close to that of liquid, and it has the characteristics of good injection performance and low viscosity (Wang et al., 2018 Li et al., 2006 Xiong et al., 2015). The following thermodynamic properties will be calculated:ĭensity, dynamic viscosity, kinematic viscosity, specific enthalpy, specific entropy, specific isobar heat capacity cp, specific isochor heat capacity cp, thermic conductivity, coefficient of thermal expansion, heat conductance, thermal diffusivity, Prandtl-number, coefficient of compressibility Z, speed of sound.Ĭalculation of carbon dioxide : if you found an error, please mail to: No garanty for correctness. Keywords: Supercritical extraction, regular solution theory, ethanol-octane mixture, carbon dioxide solvent, miscibility. Therefore, gas injection becomes an effective method to enhance oil recovery after water flooding. Lower limit for calculation: -55 C, 5,4 bar bar upper limit: 30 C, 72,14 bar. Some data obtained by the present author and co-workers using carbon dioxide at a reduced pressure, p/p c 0. Carbon dioxide behaves as a supercritical fluid above its critical temperature (304.25 K) and critical pressure (72.9 atm or 7.39 MPa), expanding to fill its container like a gas but with a density like that of a liquid (Fig. However, the knowledge of their thermophysical properties in the extended critical region is insufficient. Supercritical fluid is a fluid state where it is held at or above its critical temperature and critical pressure. Lower limit for calculation: -55 C, 1 bar upper limit: 900 C, 1000 barĬalculation of thermodynamic state variables of carbon dioxide at saturation state, boiling curve Supercritical carbon dioxide (scCO2) mixtures are essential for many industrial applications.
