188bet vn of thermodynamic properties of petroleum and refinery gases using PC-SAFT+FVT model
Summary
The PC-SAFT equation of state (EoS) combined with the free-volume theory (FVT) recently proposed (DOI: 10.1016/j.fluid.2019. 112280) is extended in this work to simultaneously predict viscosity 188bet vn some second-order derivative properties such as sound velocity 188bet vn isobaric heat capacity of some petroleum 188bet vn refinery gases. The PC-SAFT pure component parameters are obtained by providing the optimal description of its vapour pressure 188bet vn saturated liquid density data. New FVT parameters were derived for various petroleum 188bet vn refinery gases 188bet vn were validated with the National Institute of Standards 188bet vn Technology’s data over a wide range of temperature 188bet vn pressure (up to 2,000 bars). The model is simple to incorporate into the design 188bet vn simulation package such as Aspen Plus or Prosim, with average absolute deviation obtained on viscosity within the experimental incertitude (<3%), which is appropriate for most industrial applications.
Key words:Viscosities, PC-SAFT, 188bet vn, thermodynamic, petroleum gases.
