Thermodynamic Properties of Ethylene at Saturation
In the development of an equation of state for a fluid, accurate values of vapor pressure, saturated vapor density and saturated liquid density are used to define the phase equilibrium conditions for temperatures between the triple point and critical point. The vapor pressure equation and equations for the density of the saturated liquid and the saturated vapor as functions of temperature include the critical region. The equations for the saturation states are given here with comparisons to data. These equations were determined using a stepwise regression procedure1 for the selection of an optimum group of terms from the various comprehensive functions.
