Abstract
Thermodynamic properties of pure nonpolar fluids are predicted accurately, over wide ranges of temperature and pressure conditions, by the most general density-cubic equation of state. Of particular merit is the accurate prediction of liquid densities and low-temperature vapor pressures. The development of the temperature dependence and the generalization of the equation of state using thermodynamic property data for normal paraffin hydrocarbons, methane through n-decane, are presented herein. The generalized equation of state predicts vapor pressure and vapor and liquid densities to within 1% (average) of the experimental values for these fluids. The equation of state prediction of thermodynamic properties of 32 fluids is compared with the predictions by a popular density-cubic equation namely, the Peng-Robinson equation and a popular BWR-type equation of state. According to these comparisons the most general density-cubic equation is superior to the Peng-Robinson equation and is on par with the BWR-type equation of state. 60 refs.
