How is the critical point of a system calculated in PRO/II?
In the phase envelope the true critical point, cricondentherm, and cricondenbar are determined using the method of Michelsen.

In the HCURVE, the critical properties are determined according to the appropriate thermo method and the mixing rules of that thermo method.
About PRO/II: PRO/II is the major product in the Process Engineering Suite (PES). This process simulation software optimizes plant performance by improving process design, operational analysis, and performing engineering studies. It is designed to perform rigorous heat and material balance calculations for a wide range of chemical processes. PRO/II allows users to evaluate the use of heat integration with case studies, rigorously evaluate process improvements with the help of a process flow diagram (PFD), or model crude distillation units. PRO/II offers a wide variety of thermodynamic models to virtually every industry and is incredibly cost effective, decreasing both capital and operating costs.
