I'm working on a study to design a new control schematics for Crude Distillation Column Pressure Control. Any ideas for CDU pressure control strategies?

Crude unit pressure control is to be done by using Fuel gas in the over head reflux drums. Generally second reflux drum will be used for this pressure control. Fuel gas is injected to second reflux drum and pressure reliving is to be done by taking out excess vapors to flare.
