Wiley - Need new CAPE chairman from 2007 (after Rafique) Election committee: Rafique Gani + Sauro p. + Luis P. - Science Direct and Escape: will have papers from Jan. 2007; not so clear about ISI - IchEm E jounals (UK) are now official journals of EFCE -------------------- From the conference -------------------- Executive summary: At a nice location, easy to meet people, but the conference fee a bit high. Reasons for high cost: 1) Heavy printed proceeedings (about 100 Euro), 2) Lot of outside plenary speaker who need some reimbursement of travel etc. (most of whom were NOT very good..) My conclusion: (1) Forget proceedings (CD OK) and (2) use top people from our own comminity as plenary speakers (usually free!) Monday: - Presentation by Elvira on "coordinator MPC" for max. throughput. There was quite a lot if interest in this work! Unfortunateley , the talk was disrupted by computer breakdown - Optimuzation part of Yi Cao's paper was interesting! Worth checking out Monday: PSE planning meeting + Went to IPC dinner Tuesday: Plenary lecture on life cycle modelling for cobntrol by Bausa (BASF) and Dunnebier (Bayer) - Referred to RTO application from BASF Oxo plant in 1962. - They say that dynamic model is needed to derive control concepts. I disagree: Steady-state model with economics better suited, but need dynamic model for testing. - Referred to famous "80/20" rule: 80% of benefit for 20% of the effort - This applies to self-optimizing control (actually, more like 90/10). Tuesday: All the Norwegian control posters: Jørgen (LNG), Heinz (modeller), Antonio (time scale sepn.), Vinay (Branch and bound), Kristin Hestetun + Morten H. (al. electrolysis) Wednesday: Rahul (HEN talk): did not get the difficult question that Truls predicted (maybe because Chris Floudas had already left) Wednesday dinner. Sat next to (apart from Jørgen, Rahul and Truls): 1. Sajjad Ahmed, PPG, Pittsburgh (from Pakistan, working on Ph.D at late age, has been in Saudi) 2. Krisztina Cziner, post.doc. HUT, Helsinki (process design but orignally control) Thursday plenary on System biology: Hans V. Westerhoff, The University of Manchester/UK and Free University, Biocentre Amsterdam/NL "Systems biology and the silicon cell: order out of chaos" - Silicon cell = in silica = math. model - Systems biology = what comes from interactions between components in the cell. - "Biology is not stamp collecting anymore - ready for engineering". - Cannot compute all states in a cell (stochastic) - like stat. thermo When no of particles > 100 a deterministic rate equation is OK ("order out of chaos") - In bio: "Control" = gain (% scaled) - Irrev. thermo: He called Onsager relationship "Taylor term" (same as what I say!) - He claimed to have found "new" non-eq thermo (but it is same as my scaling relationship from 1991) sum_i dlny / dlnui = 1 or 0 (1 when y is extensive, 0 when intensive, ui=indep. extensive var.) "We here have two fundamental laws of non equilibrium biochemical networks that have been derived in much the same way as the Gibbs equation was derived in equilibrium thermodynamics. We therefore propose that the summation laws are aspects of the non equilibrium thermodynamic theory that was long sought after." BUT: Has really nothing to do with thermo - it is just the derivation which is similar. - I talked to him after talk and promised to send my 1991 paper ------------------------- Some papers to look at ------------------------- 1. Lek: See paper by Noda and Nishitani on optimal operation of HEN: "Flexible Heat Exchanger Network Design for Chemical Processes with Operation Mode Changes" But does not seem very good: 1) I do no think a transhipment approach with temperature intervals is needed for operation. 2) They use log-mean so they do not have an overall LP-problem 2. Knut WM, Yara: Manozca et al., "Control of the Synthesis Section of a Urea Plant by means of an MPC Controller" (Ipcos presentation that I did not attend) 3. This is relevant for Junping/Jørgen (dynamic optimization): Optimization of Operating Conditions for Ferrichrome Production in a Membrane Bioreactor Using Ustilago maydis A. Drews, H. Arellano-Garcia, M. Wendt, M. Kraume, G. Wozny from TU Berlin Nice work on optimization of dynamic process, but has not looked at implementation under uncertainty 4. Nice paper: DOF analysis. Streams + heatx/work - inventories we do not consider Degrees of freedom analysis for process control M. Rodriguez, J.A. Gayoso, Universidad Politecnica de Madrid/E 5. Self-optimzing group: Poster by Marlin Monitoring and improving LP optimization with uncertain parameters Danielle Zyngier, Thomas E. Marlin This poster received the BEST POSTER AWARD 6. BEST PAPER AWARD went to Li and Wozny, TU Berlin "Chance constrained programming approach to process optimization under uncertainty" P. Li, TU Ilmenau/D; H. Arellano-Garcia, G. Wozny, TU Berlin/D (I guess this is an extension of what the presented in Automatica a few years ago) 7. "An approach to linear control of nonlinear processes", T. Schweickhardtt and F. Allgöwer, Univ. Stuttgart (simple paper but nicely presented) (Sigurd visited Allgöwer group on Friday) 8. Ivar H.: Divided-wall paper fra UOP: "Innovative flowschemes using dividing wall columns" M.A. Schultz, D.E. O'Brien, R.K. Hoehn, C.P. Luebke, D.G. Stewart, (Dette fikk jeg ikke hørt på og jeg snakket heller ikke med ham, men etter det jeg hørte hadde de ikke bygget noe foreløpig) ------------------------------ Some more people I talked to ------------------------------ - Sven Gruetzmann from TU Hamburg-Harburg wants to come and use multivessel column - Rong from Finland wants to come and learn how to analize Petlyuk designs (use Ivars program) - Talked to Linde people: Gabriele Engl, Andreas Kröner (Jørgen visited Krøner Friday) - Talked to Muhammad Al Arfaj: Start working on updating case study for course end of August (Eduardo) - Talked to Vinay: We seemed to agree (finally) on controllability for cascade. * Wolfgang says it is OK with special issue JPC on plantwide control. Vinay puts together list. * Check if Amy Ciric did LP operation for HEN (Lek!) - Talked to Christiane Glasmacher-Remberg, Cognis. Leader of process simulation group (old group of Gorak). * Has experimental Petlyuk column! Interested in having students come and work on it! * She is looking for a Professor position, maybe Aachen - På søndag fikk jeg en liten kjøretur i Steinar Hauans nye Mercedes som har en toppfart på 300 km/t! Han hadde hatt den opp i 250 km/t, men nå skal den til USA (Pittsburgh) så der må han kjøre litt saktere... ------------------------ Visit Stuttgart 14 juli ----------------------- På ferdag etter konferansen besøkte jeg Frank Allgöwer sin gruppe i Stuttgart (der bl.a. Jørgen Kringen Johsen er Ph.D. student) Det er en meget imponerende gruppe med bra teoretisk virksomhet innen regulering. --- end Sigurds report from escape'16
