ABSTRACT:
A desired separation between sidedraw product streams withdrawn from a fractional distillation column is maintained by controlling the flow rate of the external reflux associated with a particular sidedraw product stream in response to the output signal from a temperature controller which is reset by an internal reflux controller. Such cascade control improves the stability of a fractionation process and provides for good control of the separation between sidedraw product streams.
