1 Name, title of the presentation Master project: Control structure design for a sequence of distillation columns Tor Anders Marvik Supervisor: Sigurd Skogestad Co-supervisors: Vladimoros L. Minasidis Johannes Jäschke
2 Optimal control structure of two distillation colums in a sequence Varying marked conditions Computer model Active constraint regions Self-optimizing variables Region 1: V 2, V 1, x D2,B active Region 2: x D2,B active General/systematic approach?
3 The model Based on column A by Skogestad 41 tray Feed on tray 21 Assumtions: Constant pressure Constant relative volatility Constant molar flows, No vapor holdup, Equlibrium on all stages Total condenser Steady state model in Matlab Conditions from Jacobsen
