Overordnede kursusmål
Chemical process design is about finding a sustainable process that
can convert the raw materials to the desired products cost
effectively. Chemical engineers support diverse range of sectors
and process industries, which convert raw materials to more than
70,000 products. Given this diverse set of industries and sectors
with its own domain specific equipment and standards, in this
course, the objective is to introduce students to systematic
methods for process design, to give overview of the main steps
involved in typical life cycle of a process design, as well as the
complexity of the design activity. In addition to systematic
approach for process design, we stress the importance of iterative
process analysis including economics, uncertainty & sensitivity
analysis of design assumptions, heat integration, optimization as
well as sustainability analysis of process design. In this way, the
course aims to equip students with a flexible skillset to help
design innovative, cost-competitive and sustainable processes in
diverse range of processing 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 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).
