Overordnede kursusmål
Chemical process design is about finding a sustainable process that
can convert the raw materials to the desired products in a
cost-effective manner. Chemical engineers support diverse sectors
and process industries, from chemicals and fuels to polymers,
textiles, food, and pharmaceuticals. Given this diverse set of
industries and sectors with their own domain-specific equipment and
standards, in this course, the objective is to introduce students
to systematic methods for process design, to give an overview of
the main steps involved in the typical life cycle of a process
design, as well as the complexity of the design activity. In
addition to a systematic approach to process design, we stress the
importance of iterative process analysis, including economics,
uncertainty & sensitivity analysis, heat integration,
optimization, and sustainability analysis. In this way, the course
aims to train the students with flexible skills and competencies
for conceptual process design needs across diverse process
industries.

Kursusindhold
The course consists of classroom lectures followed by group work on
the project assignment.
The course lectures follow the task-based systematic design
methodology, which introduces systematic methods and concepts for
process design as follows:
Lecture 1: Introduction to process design
Lecture 2: Process flowsheet synthesis & verification (Douglas
method)
Lecture 3: Flowsheet performance evaluation – a simple strategy
Lecture 4: Reactor Design, analysis & sizing -rigorous models
Lecture 5: Separation process design & sizing -rigorous models
Lecture 6: Sensitivity Analysis in Process Design
Lecture 7: Capital and Production Cost Estimation
Lecture 8: Economic Assessment and Uncertainty Analysis
Lecture 9: Process and Flowsheet Optimization
Lecture 10: Heat Integration and HXN design
Lecture 11: Sustainability Analysis in Process Design
The project assignment which is worked in groups of e.g. 3 members
contains three parts that builds on each other:
Part 1. Scope of Design
Implement the conceptual process in a simulator of your choice
(Aveva or excel spreadsheet). Report and discuss mass and energy
calculations (Lectures 1 to 5).
Part 2. Process economics and uncertainty analysis.
Perform cost estimation, economics, sensitivity & uncertainty
analysis, and discuss the results (Lectures 6 to 8)
Part 3. Advanced process analysis (e.g. process optimization, heat
integration, and sustainability analysis)
Perform optimization, heat integration, and sustainability
analysis, compare/benchmark other alternatives, and discuss the
results. (Lectures 9 – 11).
Each part will be followed by selected group presentations (each
group will present at least one part of the assignment).
