Title: Thermodynamic consistency test procedure using orthogonal collocation and the Peng-Robinson equation of state

Technical Report ·
DOI:https://doi.org/10.2172/6771265· OSTI ID:6771265

The Christiansen and Fredenslund programs for calculating vapor-liquid equilibria have been modified by replacing the Soave-Redlich-Kwong equation of state with the newly developed Peng-Robinson equation of state. This modification was shown to be a decided improvement for high pressure systems, especially in the critical and upper retrograde regions. Thermodynamic consistency tests were developed and used to evaluate and compare calculated values from both the modified and unmodified programs with reported experimental data for several vapor-liquid systems.
