Following is a very common chain of events that
contributes to wasted energy in distillation:
- Human nature leads many to increase reflux when an
overhead specification isn't met (when a decrease in
reboil might be a more energy-efficient move).
- The increased reflux can cause lights to drift up in
the bottom of the tower, which may cause many to increase
reboil (when a decrease in reflux might be the more
energy-efficient move), which can cause heavies in the
overhead to drift up again.
- Result: One increases reflux, another increases reboil…The
cycle continues until the tower gets "wound up."
- The same chain of events can also start at the bottom of the
tower when lights in the base trend higher and reboil is added rather than cutting reflux.
- Other ways that this suboptimum energy point is reached includes not making a
tower adjustment when feed flow or composition shifts, or if ambient temperatures swing night to day or season-to-season.
