Chapter 7. Approximate Shortcut Methods for Multicomponent Distillation
Chapters 5 and 6 served as an introduction to multicomponent distillation. Matrix methods are efficient, but they still require a fair amount of time even on a fast computer. In addition, they are simulation methods and require a known number of stages and a specified feed plate location. Fairly rapid approximate methods are required for preliminary economic estimates, for recycle calculations where the distillation is only a small portion of the entire system, for calculations for control systems, and as a first estimate for more detailed simulation calculations.
In this chapter we first develop the Fenske equation, which allows calculation of multicomponent separation at ...
