- Develop personal attitude.
- Develop thinking habits.
- Objectively compare and select different technical options for chemical processes.
- Work in a team.
Learning Outcomes
- Develop a capacity for analysis, synthesis and prospection.
- Develop curiosity and creativity.
- Develop scientific thinking.
- Identify the fluid circulation operations involved in the design of heat transmission systems.
- Objectively compare and select the different technical options for heat transmission systems.
- Work cooperatively.

Multiple effect evaporators
Methodology
This subject has been deprogrammed from the teaching calendar when the new Chemical Engineering degree came into operation. Tutoring sessions at the request of students will replace unscheduled teaching
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.
