Differences between DEW, DEWW, and DEWHC flashes in PRO/II

The DEW flash calculates the temperature or pressure when the first drop of liquid appears; in the case of a hydrocarbon/water mixture, this may be either water or hydrocarbon.  
The DEWW flash calculates the temperature or pressure when the first drop of water condenses whereas the DEWHC flash calculates the temperature or pressure when the first drop of hydrocarbon condenses.

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.
