Calculation of Critical Points by the Method of Heidemann and Khalil

摘要

The formulation of critical point criteria by Heidemann and Khalil is analyzed and contrasted with the original formulation of Gibbs. An extension to the solution technique originally used by Heidemann and Khalil, and later improved by Michelsen and Heidemann, is presented along with its detailed implementation for a general two-constant cubic equation of state. Finally, FORTRAN software developed for these computations is carefully documented.
