COURSE DESCRIPTION |
Course objectives |
Students are introduced to the theoretical concepts and the application of separation unit operations in chemical engineering that are necessary in a systematic problem solving of procedures related to the mediterranean cultures. Acquired knowledge allows them to evaluate and select the optimal separation process and introduces them to equipment designing with a special emphasis on optimizing the process operating conditions. |
Course enrolment requirements and entry competences required for the course |
|
Learning outcomes expected at the level of the course (4 to 10 learning outcomes) |
After passing the exam, the student are expected to: - acquire the basic theoretical knowledge of an advanced separation processes that are applied in chemical engineering - know how to apply a basic methodology of chemical engineering necessary in a selection of an appropriate processes and devices used in chemical engineering and to define and optimize the process parameters to increase process efficiency - develop a critical approach towards a certain procedures in chemical engineering in terms of their selection, advantages, disadvantages and applications - adopt a methodological approach in device designing that are used in separation engineering |

Grading and evaluating student work in class and at the final exam |
A student can pass a part or the entire exam by taking two partial tests during the semester. Examination passing rate is 55%. Students who do not pass the partial exams have to take an exam in the regular examination periods. The exam consists the theoretical (oral) part. Oral part will constitute 70%, laboratory exercises and field work will constitute 30% of the final score. |
