A control system for a fractional distillation column, where the feed to the fractional distillation column is supplied from at least one separator, is disclosed in which overloading of the fractional distillation column is prevented by monitoring a control parameter associated with the fractional distillation column which indicates that the fractional distillation column is being overloaded. The flow of the feed from the at least one separator is manipulated to maintain the control parameter which indicates that the fractional distillation column is being overloaded within desired limits. The feed to the at least one separator is manipulated to maintain the liquid level in the at least one separator within desired limits.
