Special course in control engineering
419511.0
5 credits
Advanced level
Lectures or project work
Offered: Upon agreement
Lecturer: Jari Böling
Aim: Further studies in some special (advanced) area of control
engineering.
Course website:
Contents: The course may be an advanced (lectured) course
not given regularly, or some other advanced course offered
by the process control laboratory, e.g.
- Control of Discrete Event Systems (419502)
- Laboratory Course in Control Engineering (419505)
According to agreement with the teacher, the course can also
be a project consisting of experimental, calculation, simula-
tion, or similar studies. A report is written about the work and
presented in a seminar.
Target group: Students of theMaster's Programme in Chemi-
cal Engineering or other students not taking the regular
control engineering courses.
Process Design and
Systems Engineering
One of the many tasks a chemical engineer needs to master
in his/her work is the overall design of processes. Knowledge
and understanding is needed about basic unit operations,
mass and energy balances, sizing of units and pipes, mod-
eling, planning and optimization. All this is part of process
design and is reflected in the courses that are given at the
laboratory. The laboratory also gives courses in energy and
environmental technology as well as planning and evaluation
of experimental work using statistics. A few of these courses
are offered in English.
The research at the process design laboratory is conducted
in three distinct areas:
.
Process and production optimization, where the main
focus is on the development of numerical methods and
models for solving mixed-integer non-linear program-
ming (MINLP) problems with applications in process
synthesis and production planning. In this area the
laboratory leads a center of excellence in Optimization
and Systems Engineering funded by the university.
.
Environmental engineering, where fluegas desulphuriza-
tion and the limestone based absorbents that are used
for this process are examined.
.
Energy technology, where special interest has been put
on simultaneous heat and mass transfer in paper drying
and gasification of organic matter in water at supercriti-
cal conditions.

Intermediate level
Lectures and exercises
Offered: Autumn 2014
Lecturer/Contact: Frej Bjondahl
Aim: The aim of the course is to train the student to solve
process design problems. Mass and energy balances are set
up using block flow diagrams and are used for calculation of
mass andenergy flows inprocess systemswhile equipment for
storage, preprocessing, reaction, separation, heat exchange
and transport are described and roughly sized based on the
mass and energy flows in such process systems. Elementary
instrumentation for control and cost estimates is also made.
Learning outcome: After completing the course the student
is expected to be able to set up and solve mass and energy
balances and to select and size process equipment as well as
make cost estimates.

Teaching methods: The central parts of the course are dem-
onstrated during lectures and trained in exercise assignments.
Forms of examination: Written examinationwith calculations.
All aid is allowed apart from computers and calculators with
internet access. All exercise assignment reports must be ap-
proved before taking part in the exam.
Target group: The course is intended for students in the
Master's Programme in Chemical Engineering as well as
international exchange students.

Advanced level
Project work, seminars
Offered: Autumn 2014
Lecturer/Contact: Frej Bjondahl
Aim: The aimof this course is to give the students insight into
themethodology that is used in process plant design and the
various phases the work goes through. The course is a project
work which consists of the planning of a process. During the
course the students will calculate mass and energy balances,
select equipment sizes andplan the instrumentation. Theywill
also simulate the process as well as drawblock flowdiagrams
and piping and instrumentation diagrams. An introduction
to process simulation with Aspen Plus and technical drawing
with AutoCAD will be given during the course.
Learning outcome: After completing the course the student is
