Prerequisites
No official requirements are defined for this course. However, we strongly recommend that the student has passed the first year courses of Physics, Chemistry, Computer Applications and Balance in Chemical Engineering.
Objectives and Contextualisation
The principles of Thermodynamics and their application in Chemical Engineering are presented. From the formulation and discussion of thermodynamic principles, these are used to determine the properties of pure fluids and mixtures. A fundamental objective is the thermodynamic analysis of systems in equilibrium, both physical balance between phases, and the balance in systems with chemical reaction. In both cases, it is about the quantification and analysis of the balance for its future application in the design of reactors and unit operations.
Competences
- Chemical Engineering
- Communication
- Develop personal work habits.
- Develop thinking habits.
- Understand and apply the basic principles on which chemical engineering is founded, and more precisely: balances of matter, energy and thermodynamic momentum, phase equilibrium and kinetic chemical equilibrium of the physical processes of matter, energy and momentum transfer, and kinetics of chemical reactions
Learning Outcomes
- Apply the scientific and technological basics of thermodynamics, phase equilibrium and chemical equilibrium and the kinetics of physical energy transfer processes.
- Communicate efficiently, orally and in writing, knowledge, results and skills, both professionally and to non-expert audiences.
- Develop critical thinking and reasoning
- Work autonomously.

Methodology
Guided activities:
Theoretical classes: Master classes on the topics of the syllabus.
Problem classes: solving problems related to the subject. Discuss with the students about the solution strategies and their execution.
Simulator use seminars: Presentation seminars for the use of process simulators in the estimation of thermodynamic properties and equilibrium compositions.
Autonomous activities:
Study: Individual study. Schemes and summaries preparation.
Problem solving: Self-solving problem solving. On the one hand, as a complement to the own study of the subject and, on the other, as a preliminary work to the classes of problems.
Use of process simulator to estimate properties and solve equilibrium problems between phases of multi-component systems.
Search for documentation and bibliography: Check the essential documentary resources for the course.
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.

Assessment
Evaluation by course:
1st partial test (PP1) (topics 1 to 5): 40% grade.
2nd partial test (PP2) (topics 6 and 7): 45% grade.
Work with process simulator: 15% note.
You have to obtain a 3/10 in the theoretical part of each partial test and 3/10 in each partial test to pass the subject per course.
Single assessment: those who accept the single assessment process by declaring it at the beginning of the course, will take the day of the second partial test, an additional part corresponding to the first part of the course.
Retaking exam:
There will be a final global test for those students who have not passed the continuous assessment (note <5).
