MCS Profiles Total Reflux

Equation 9.12 implies that both flows and compositions are the same at the top of the MCS. This is equivalent to describing a total reflux column, and also sufficiently expresses an infinite reflux column, as discussed by Peters et al. [13]. Refer to Chapter 2 (Section 2.6) for the equivalent discussions on total and infinite reflux in simple distillation columns. 

The conditions of total reflux result described in Equation 9.12 lead to 

It is interesting to note that Equation 9.14 is mathematically similar to the residue curve equation for distillation processes (refer to Equation 2.8). As one may recall from preceding chapters, this simplification of the MDPE under total reflux conditions is comparable to the simplification of the distillation-based DPE under infinite reflux conditions.
