The divided wall column has been recently spotlighted as a
promising separation process from its energy saving capability.
The divided wall column can save the energy and equipment cost
of about 30–50% in comparison with the conventional distillation
sequences [1–4]. All over the world, the divided wall column of
about 40 is operated and 30 is operated in the BASF group [5].
The divided wall column is the complicated distillation system
consisting of a prefractionator and main column. Despite economic
efficiency of the divided wall column, control and operation of the
column are considerably difficult [9,10]. Presently, the conventional
control strategy using the PI controller is used but effect of
the energy saving is not obtained by operating at non-optimal region
considering the safety margin due to the control difficulty.
