Abstract

The performance of various vapor-liquid equilibrium calculations requires phase equilibrium data. One of the most versatile sources of this data is an equation of state, re-lating the pressure, temperature, and phase compositions it a single expression. The equation under study herewith is the eight constant Benedict-Webb-Rubin Equation of State.

This paper provides a computer program which evaluates the following types of phase equilibria: bubble-points, dew-points, and two phase flash calculations. Also included in this paper is the theoretical backround of the Benedict-Webb-Rubin Equation of State, calculational techniques, and the data used in the program.
