Editorial Note

The Network in Chemical Process Control represents a joint effort of thirteen European Departments, with two main stated objectives -

  1. To provide extensive training for young postdoctoral workers in this important European industrial area,
  2. To give the members of the research community in chemical process control the opportunity to develop or reinforce collaborations on topics grouped in three main themes - (i) Modelling and Identification of Chemical Plants; (ii) Monitoring and Control of Non-linear Chemical Processes; and (iii) Tools for Controllability Analysis and Control Strategy Decisions.

In the London Meeting, of September 15-16 1995, The Group decided for the publication of this Newsletter, seen as an effective way to keep Researchers in the area, belonging or not belonging to the Network, informed about our activity and efforts of cooperation.

The job for the Editors is essentially that of compiling in appropriate form for publication the information which the different partners may decide to provide.

The Electronic Mail communications system, the capacity of GETting files through FTP and the World-Wide-Web represent major tools for dissemination of information. We shall keep files of an 'Online Newsletter' in Word and Word Perfect formats, in a FTP ANONYMOUS location. It will be possible to get them with the FTP tool. This Newsletter will also be available in the WWW system. From this page, it will be possible to get into the different individual pages of Researchers, of Departments, of Universities, to have access to abstracts of publications or full publications, you name it...

Please, do contact us by E-Mail. We look forward to hearing comments and suggestions from you and to receiving news for publication.

1.3 Network internal organization

The activity of the network has been organized in six subgroups, corresponding to the areas
of research which fitted best with the envisaged activities of cooperation.

A coordinator has been designated for each of such subgroups -

  • SB_1 - Modelling tools and Computer-Aided Design (coordinator Wolfgang Marquardt)
  • SB_2 - Identification for control (Dominique Bonvin)
  • SB_3 - Nonlinear estimation and control (Pierre Rouchon)
  • SB_4 - Real-time optimisation (John Perkins)
  • SB_5 - Process monitoring and data interpretation (Julian Morris)
  • SB_6 - Controllability analysis (Siegurd Skogestad)

Information on Mobility

  • On the 1st of February, 1996, Dr. Bernhard Dahm (from Stuttgart) started a period of 9 months of postdoc work in Porto, under the auspices of the network. He will work on the development of AI methodologies for state estimation and control of biorectors.
  • In 1995, from September 29 to October 10, Achim Helbig (RWTH) visited Lausanne and worked on the subject: 'Modelling, on-line estimation and optimization of batch chemical reactors'.
  • In 1995, from 2-6 October, Benjamin Bonnet (PhD student) of CESAME visited Exeter to become familiar with experimental work carried out at Exeter on the modelling and control of a pilot-plant scale activated sludge process.
  • In 1995, from July 10 to September 12, Michael Amrhein (from EPFL) visited Newcastle and worked on the topic 'Hybrid modelling of chemical and biochemical batch processes'. On the same topic, Dr. Libei Chen (Newcastle) is to visit Lausanne, from December 5, 1995, till January 15, 1996.
  • In 1995, September, by occasion of the ECC95 Conference in Rome, a Meeting of Theme 6 took place to discuss future activities of Theme members - Diane B. Rossiter (Exeter), Jorgensen (DTH), Haggblom (Abo), Hovd (NTH), Perkins (ICSTM), Skogestad (NTH), Waller (Abo), Walsh (ICSTM)). Also the meeting was attended by Dr Elling Jacbsen, STH, Sweden and Prof. Claudio Scali, Pisa both are interested in becoming involved in the future TMR network proposal.
  • In 1995, The Centre for Process Systems Engineering (IC London) has welcomed two visitors under the auspices of the network and some of their Members were Visitors to other Institutions:
    • Jean-Christophe Culioli (École des Mines) spent about 6 weeks in the Centre between March and June 1995. During this time he worked with many people in the Centre and exchanged papers and ideas.
    • Cristiano Cortonesi (Pisa), a student of Claudio Scali's, worked in the Centre for two months, with Steve Walsh, on using MILP techniques for control structure selection and made a modest contribution to work in this area. He gave a seminar on the work back in Pisa.
    • Three members of the Centre, Steve Walsh, Eva Sorensen and Jezri Mohideen attended the meeting in Stuttgart on distillation control. Jezri presented a paper there.
  • In 1994/95 Mike Papzoglou and George Murikas from Thessaloniki spent 9 months in Newcastle
  • In 1994, December, Dr Diane B. Rossiter visited Dr Pierre Rouchon at Ecole de Mine, Paris.

Past Events
      One-day workshop in Paris on Nonlinear Estimation and Control
      The workshop took place, on Friday 19 April, in Paris, at Ecole des Mines, organized by Dr. Pierre Rouchon.

      One-day workshop on Plantwide Control and Controllability (Lyngby)
      The workshop took place, on 20 May 1996 in Lyngby. Each member of the theme was represented. However, attendance was not restricted to members of the Network so Elling Jacobsen (KTH, Sweden) and Morten Hovd (Fantoft Prosess, Norway) were invited. Eight presentations were given over the day on a variety of topics ranging from the effect of recycles on the plant zero dynamics (presented by Elling Jacobsen) to issues in control structure selection (presented by Professor Sigurd Skogestad). The attendants also had the opportunity to see the energy-integrated distillation column in the pilot plant at DTH. The day concluded with a discussion on the theme's contribution to the proposal for the Teaching and Mobility of Researchers chaired by Dr Walsh. This proposal incorporates new members namely, Dr Hovd, Fantoft Prosess (Norway), Professor Scali, Pisa University (Italy) and Dr Jacobsen, Royal Institute of Technology (Sweden).

Forthcoming Events

6. Other Activity
  1. It is being prepared a visit by Dr Steve Walsh (ICSTM) and Dr Diane B. Rossiter (Exeter) to Prof Waller (Abo Akademi), Prof Jorgensen (DTH) and Prof Skogestad (NTH) in February 1996 to discuss joint collaboration under Theme 6 and possible BRITE-EURAM proposals on distillation and, pulp and paper industry.
  2. Also, work is in progress of preparation of a TMR proposal for submission in 1996.

7. Special Topics
  • From Julian Morris, we have received in January 24 (1996) the following call for cooperation -
    We have a lot of work going on with the paper industries. We would be interested in working with colleagues in this area. Our links are with Argo Wiggins, Calladonian, BPB, KNP Fine Paper (Netherlands), A Swedish company, Voit, SKF Condition Monitoring on paper plant bearings, etc.

  • From Dominique Bonvin, we have received the following remark -
    It has been our experience that there is a high demand for mobility exchanges of short duration. We personally question the real value of stays under, let us say, 2 months. Comments welcome.
