What are the differences between the three tray efficiency methods? Which is easiest to use?

Posted on 21:00 by Unknown
The three tray efficiency models are Murphree, Vaporization, and Equilibrium.  The easiest to use is vaporization.

Vaporization efficiency is a multiplier applied to the equilibrium K-values.

Murphree efficiency is defined in textbooks and some values may be available in the literature.

Equilibrium efficiency is a combination of vaporization and Murphree.




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.
Technical Support: As always, feel free to reach out to your local technical support team for more information.
