Prerequisites

It is recommended to have passed the following subjects:

- Basic Operations of Chemical Engineering

- Applied thermodynamics


Objectives and Contextualisation

The objective of the subject is the study of the principles of heat transmission and its application to the calculation and design of heat exchangers and evaporators.


Competences

  • Demonstrate knowledge of the different reaction, separation and processing operations for materials, and transport and circulation of fluids involved in the industrial processes of chemical engineering.
  • Develop personal attitude.
  • Develop thinking habits.
  • Objectively compare and select different technical options for chemical processes.
  • Work in a team.

Learning Outcomes

  1. Develop a capacity for analysis, synthesis and prospection.
  2. Develop curiosity and creativity.
  3. Develop scientific thinking.
  4. Identify the fluid circulation operations involved in the design of heat transmission systems.
  5. Objectively compare and select the different technical options for heat transmission systems.
  6. Work cooperatively.

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.
