Column profile maps

Assuming that only the first-order derivative is significant [3,4] and noting that Ak = k—(n—1)= 1, Equation 3.7 reduces to 

It is worth noting that the DPE is based on the pioneering work by Doherty and coworkers [2 6] for conventional (nongeneralized) rectifying and stripping sections, as found in simple columns. It will be shown in Chapter 5 how the generalized DPE can be applied to these conventional distillation sections, and in fact produce the same result. 

In this section, column profiles and eventually entire column profile maps (CPMs) will be generated. The discussions and interpretations that are given relate somewhat to the operation of a CS, but are mostly done from a mathematical and topological perspective. Once understood, these aspects of CPMs will be used to appreciate the physical operation of various CSs.

A reader familiar with distillation research will find much of the material in this chapter to be famihar. However, RCMs do form the fundamental backbone of column profile maps (CPMs), and thus the need for this chapter is important. Readers that are experienced with distillation may find Section 2.9, particularly interesting and useful when some not-so-common ways of looking at RCMs are discussed.
