In the distillation column shown in Figure 18.10, changes in the feed composition give rise to noncondensables
Question:
In the distillation column shown in Figure 18.10, changes in the feed composition give rise to noncondensables in the tower overhead vapor. Devise a new control scheme for the tower top pressure. It is also desired that instead of controlling the composition of the tower top product, the tower top temperature is controlled as a surrogate control obejective. Modify the existing control scheme accordingly.
