WebIt has been reported that both Peng-Robinson and Span-Wagner equations have been used in the energy industry for CO2 pipeline simulation. This paper will present the results using different Equations of State for CO2 simulation. Different commercial software packages have been tested. WebThe very accurate Helmholtz energy equation of state of Span and Wagner [ 7 ] (Model FEQ in NIST REFPROP®-Software) was used within the limits: -56,558 °C to 1726,9 °C, p < 8000, bar, density lower than 1638,9 kg/m³ to calculate the density-pressure and pressure-temperature diagrams.
WebActually, the most accurate models are the multi-parameter Helmholtz energy equations of state (MEoSs). Simpler models are available, generally written in terms of cubic polynomials of the density. These cubic equations of state (CEoSs) are widely used, and, sometimes, preferred to MEoSs for the easiness of implementation and use.
