Abstract
A control system for a fractional distillation column in which a pumparound stream is used to remove heat from the fractional distillation column is disclosed. A combination of feedforward and feedback control is utilized to control the heat removal by the pumparound stream in such a manner that smoother operation of the fractional distillation column will be accomplished and a closer approach to required product specifications will be approached.
