The Relationship Between RCMs and CPMs

Having established that there are topological similarities between CPMs and RCMs, it is of interest to determine what the exact relationship between the two is. In Section 2.6.2, it was shown that a liquid profile in a total reflux column follows a residue curve exactly, and that the liquid composition in an infinite reflux column will sufficiently approximate a residue curve too. Thus, it should come as no surprise then that when taking the limit in the DPE such that we observe that the DPE 

One may then say that CPMs, which are affected by various parameters, can be classified for general operation, while an RCM is for more specific operation. The ROM is a single, special member of the family of CPMs that can possibly describe the workings of a CS.
