| Abstract | This course encompasses the theoretical principles of chemical process simulation and optimization, as well as its practical application in process analysis. The techniques for simulating stationary and dynamic processes are presented, and illustrated with case studies. Commercial software packages (Aspen) are introduced for solving process flowsheeting and optimization problems. |
| Learning objective | This course aims to develop the competency of chemical engineers in process flowsheeting, process simulation and process optimization. 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 should 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 to develop criteria to correctly use commercial software packages and critically evaluate their results. - Process optimization: the students will learn how to formulate optimization problems in mathematical terms, the main type of optimization problems that exist (i.e., LP, NLP, MILP and MINLP) and the fundamentals of the optimization algorithms implemented in commercial solvers. |

| Prerequisites / Notice | A basic understanding of material and energy balances, thermodynamic property methods and typical unit operations (e.g., reactors, flash separations, distillation/absorption columns etc.) is required. |
Performance assessment
| Performance assessment information (valid until the course unit is held again) | |
Performance assessment as a semester course | |
| ECTS credits | 6 credits |
| Examiners | G. Guillén Gosálbez |
| Type | session examination |
| Language of examination | English |
| Repetition | The performance assessment is offered every session. Repetition possible without re-enrolling for the course unit. |
| Admission requirement | The assessment is based on a written exam (70%) and the coursework (30%). Both marks should sum up 4 out of 6 points (or 60 points out of 100). |
| Mode of examination | written 180 minutes |
| Additional information on mode of examination | The compulsory continuous performance assessment is based on a set of exercises that represent 30% of the total mark. The compulsory continuous performance assessment task needs not to be passed on its own. The module is passed with 4 out of 6 points (i.e., 60 out of 100), where the total mark comes from the exam (70%) and the coursework (30%). |
| Written aids | All learning material (books, lecture notes, personal notes etc.) and calculation means (calculators, scientific calculators, personal laptops etc.) are allowed |
| This information can be updated until the beginning of the semester; information on the examination timetable is binding. | |
