Direct material coupling between column sections in distillation leads to energy efficient systems like
the Petlyuk column but with more difficult control problems compared to conventional multicomponent
distillation sequences. A control study of a four-product extended Petlyuk column operating close to
minimum energy is reported here. We study the “ideal” case with all steady state degrees of freedom
available for control, including the vapor split valves, which is required to achieve minimum energy
under all conditions. Four decentralized control structures are proposed and tested against a wide range
of disturbances. This work demonstrates also the use of the graphical Vmin tool which can be used to
visualize the minimum boilup requirement for Petlyuk arrangements
