widening the reactive stripping section. Figure 6.20 gives the effects of the number of reactive trays on the temperature and composition profiles.

6.3.6 Number of Rectifying Trays

Increasing the number of rectifying trays decreases the vapor boilup (lower left graph, Fig. 6.19), but not by much. The almost invariant temperature profiles from simulation confirm this insensitivity. There is no counterintuitive effect.
