9 20 full-time academic staff 60 Ph.D. students 70 Master students annually Department of Chemical Engineering at NTNU

10 Research and faculty There are six main research areas in the department: Polymer and colloid chemistry Catalysis and petrochemistry Process systems engineering (Skogestad, Preisig) Reactor technology and CFD (Svendsen) Separation technology Pulp and paper technology Ugelstad particles

11 Process control group at Department of Chemical Engineering Professor Sigurd Skogestad Marius Govatsmark Audun Faanes Hilde Engelien Stathis Skouras Espen Storkaas Vidar Alstad Federico Zenith Heidi Sivertsen Antonio Brandao Elvira Aske Jens Strandberg Jørgen B. Jensen Eduardo Hori (visiting Ph.D. student from Brasil)

12 Research: Develop simple yet rigorous methods to solve problems of engineering significance. Use of feedback as a tool to 1. reduce uncertainty (including robust control), 2.change the system dynamics (including stabilization), 3.generally make the system more well-behaved (including self-optimizing control). limitations on performance in linear systems, control structure design and plantwide control, interactions between process design and control, distillation column design, control and dynamics. Natural gas processes

13 Optimal operation in practice: "The goal is to find a self-optimizing control structure where acceptable operation under all conditions is achieved with constant setpoints for the controlled variables."

14 Self-optimizing Control – Illustrating Example Optimal operation of Marathon runner, J=T –Any self-optimizing variable c (to control at constant setpoint)? c 1 = distance to leader of race c 2 = speed c 3 = heart rate c 4 = level of lactate in muscles

15 Group work Main objective: Suggest collaborative research project(s) for the “new” Ph.D. students in your group. Should be possible to include in Ph.D. thesis. Topic should be such that a paper can be finished within 5 months (Feb. 2003) For each project make a transparency with: Title: …………………….. Suggest names or desired background (at least two people from different groups) (e.g., Elvira Aske + one from Bolland’s group) Short abstract:……….. Extra task (one transparency each): Ideas for seminars, social events, etc. for the Natural Gas Systems Group
