ABSTRACT:
A fractional distillation process, in which the flow rate of the external reflux is utilized to control the bottoms product composition, is controlled so as to maintain a desired bottoms product composition to the extent that maintaining the desired bottoms product composition does not cause a process constraint to be violated. A plurality of actual process conditions are compared to process constraints for those process conditions to determine if the flow rate of the external reflux should remain the same, be increased by an incremental amount or be decreased by an incremental amount. The order of the comparison of process constraints to actual process conditions is such that the most important comparison will control the external reflux flow rate if that comparison indicates that a process constraint has been violated.
