Prerequisites

Having assisted to Termodinàmica Aplicada


Objectives and Contextualisation

The main objective of the subject is that the student learns to select, analyze and design different separation operations controlled by the mass transfer and the heat transmission
 

The specific objectives of the subject are :

• Understand the different separation operations, their modes of operation and possible applications.

• Understand the physical concepts and fundamentals of each operation studied.

• Use common and illustrative methods of calculation of separation systems

• Design the most common separation equipment


Competences

  • Analyse, evaluate, design and operate the systems or processes, equipment and installations used in chemical engineering in accordance with certain requirements, standards and specifications following the principles of sustainable development.
  • Develop personal work 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

  1. Analyse, evaluate and design general chemical plant services.
  2. Apply and identify basic concepts related with chemical engineering.
  3. Apply the scientific and technological basics of balance and transfer of matter and separation operations.
  4. Apply the scientific and technological basics of matter transfer to separation operations.
  5. Make one's own decisions.
  6. Work autonomously.

Exercice 7 0.28 1, 2, 3, 4, 5, 6
Study 28 1.12 2, 4, 5, 6

During the course there will be master classes where the concepts of subject topics will be introduced. In each topic, the examples of calculation or design will be introduced and problems will be given for home work. One exercice will be carried out at home which will be scored.

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

Continous Assessment Activities

Title Weighting Hours ECTS Learning Outcomes
Exercise 15 7 0.28 1, 2, 3, 4, 5, 6
Final test 40 4 0.16 1, 2, 3, 4, 5, 6
Retake exam 85 7 0.28 2, 4, 5, 6
Test 1: Flash and binary distillation 20 2 0.08 1, 2, 3, 4, 5, 6
Test 2: Multicomponent and batch distillation, Absorption and column design 25 2 0.08 2, 4, 5, 6

The subject will be evaluated by means of an exercice (15% of the mark) and 3 tests: 2 tests (20 and 25% of the mark each) and an exam final (40% of the note). Students who do not pass the subject will have a retake exam that will have at least one exercise of each of the three tests.
A student will be considered non-evaluable (NA) if it has not assisted in to a minimum of 60% of the total grade of the subject (that is, at least one partial test and final test).

For each assessment activity, a place, date and time of revision will be indicated in which the student will be able to review the activity with the teacher. If the student does not submit to this review, this activity will not be reviewed later.

Honor enrollments Granting an honorific matriculation qualification is a decision of the faculty responsible for the subject. The regulations of the UAB indicate that MH can only be awarded to students who have obtained a final grade of 9.00 or more. It can be granted up to 5% of MH of the total number of students enrolled.

Notwithstanding other disciplinary measures deemed appropriate, the irregularities committed by the student that can lead to a variation in the rating of an evaluation act will be graded with a zero. Therefore, copying, plagiarizing, cheating, copying, etc. In any of the assessment activities it will imply failing  with a zero. Assessment activities qualified in this way and by this procedure will not be recovered
