529-0613-01 GProcess Simulation and Flowsheeting
Some of the available dates of the course "Case Studies in Process Design" on Wednesdays, 2-6 pm, are used for exercises in "Process Simulation and Flowsheeting" (e.g. with Aspen, gPROMS, Matlab, etc.). The participation in these exercises is considered critical for understanding and practicing the content of the course, and therefore, preparing for the written exams. Every student is asked to hand a report for these exercises. The reports are corrected and graded to provide the necessary feedback to the students.

KurzbeschreibungThis course encompasses the theoretical principles of chemical process simulation, as well as its practical application in process analysis and optimization. The techniques for simulating stationary and dynamic processes are presented, and illustrated with case studies. Commercial software packages are presented as a key engineering tool for solving process flowsheeting and simulation problems.
LernzielThis course aims to develop the competency of chemical engineers in process flowsheeting and simulation. Specifically, students will develop the following skills:
- Deep understanding of chemical engineering fundamentals: the acquisition of new concepts and the application of previous knowledge in the area of chemical process systems and their mechanisms are crucial to intelligently simulate and evaluate processes.
- Modeling of general chemical processes and systems: students have to be able to identify the boundaries of the system to be studied and develop the set of relevant mathematical relations, which describe the process behavior.
- Mathematical reasoning and computational skills: the familiarization with mathematical algorithms and computational tools is essential to be capable of achieving rapid and reliable solutions to simulation and optimization problems. Hence, students will learn the mathematical principles necessary for process simulation and optimization, as well as the structure and application of process simulation software. Thus, they will be able develop criteria to correctly use commercial software packages and critically evaluate their results.
