Arbeids- og læringsformer

Lectures, exercises and assignments are used.

Lectures, including calculation examples and key derivations, are used to highlight the main topics of the course, facilitating knowledge.

The calculation examples (on the blackboard) are meant to inspire students to carry out their own activities. For this purpose exercises are given on a regular basis (basically one exercise per week), covering all main topics in the course, and incorporating the main methods and techniques used to solve gas purification and process optimization problems. By working on the problems given in the exercises, the students will gain skills as well as knowledge (a higher level of comprehension).

During the semester, the students will also work on an assignment resulting in a report on a given gas purification subtopic. Through this the students will gain general competence in writing scientific reports, including how to cite and reference sources. The assignment will also contribute to knowledge (a deeper level of understanding) within one specific subtopic.

Vurderingsformer

The final test counts 60 %; the mid-term test counts 25 %; the assignment counts 15 %. Grades A-F are used. To pass the course, the final test must be passed.

The final test and the mid-term test are used to assess knowledge and skills. The assignment is used to assess knowledge, skills and general competence.
