The requirements of thermodynamic data predictors in process simulation applications are especially rigorous. The calculation of vapor and liquid density by the Benedict, Webb, Rubin, Starling equation of state has been reformulated to better satisfy these requirements; the necessary mathematical and programming techniques have been developed and are presented here. The resulting algorithm is believed superior for process simulation purposes.
