“…Among the more recent investigations related to RVP estimation is the work of Shiller (1986), from the Ford Motor Company, who developed a computer model based on the assumption that gasoline vapor-liquid equilibria can be predicted with reasonable accuracy from Raoult's law for ideal mixtures. The general vapor pressure and temperature relationship used in the model is based on the published work of Van Nes and Van Western (1951) shown above by Eq.…”

A new correlation is developed for predicting the Reid vapor pressure (RVP) of gasoline and naphtha based on a true vapor pressure (TVP) correlation. The input parameters for this correlation are the mid-boiling point, specific gravity, critical temperature, and critical pressure, where the critical properties may be estimated from the boiling point and specific gravity using available methods. The proposed correlation is evaluated with data collected on 50 gasoline samples from crude oils from around the world with API gravity ranges from 41 to 87, average boiling point ranges from 316 to 494 K and RVP of 0.007 to 1.15 bars (0.1-17 psia). The average error from the proposed correlation is about 0.06 bar (0.88 psia). Two other simple methods for prediction of RVP available in the literature have been evaluated with the same data bank and compared with the proposed method.
