Prerequisites

To have attended the subject Chemical Engineering Fundamentals


Objectives and Contextualisation

The main objective is to select and design equipment based on the circulation of fluids existing in any industrial plant.

Other more specific objectives:

  • Apply the mechanical energy balance to the study of the fluid flow.
  • Study and dimension the equipment for the transport of incompressible fluids.
  • Know the necessary instrumentation or based on the fluid flow.
  • Expand the application of the mechanical energy balance to the circulation of compressible fluids.
  • Understand the foundation of unit operations based on the fluid flow.
  • Design the equipment of the most relevant unit operations.
  • Consolidate theoretical concepts through experimentation in laboratory assemblies.

Competences

  • Apply scientific method to systems in which chemical, physical or biological transformations are produced both on a microscopic and macroscopic scale.
  • Assume the values of professional responsibility and ethics required in chemical engineering.
  • Develop personal attitude.
  • Develop personal work habits.
  • Students must be capable of applying their knowledge to their work or vocation in a professional way and they should have building arguments and problem resolution skills within their area of study.
  • 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
  • Work in a team.

Learning Outcomes

  1. Apply scientific method to perform macroscopic balances of matter, energy and momentum.
  2. Identify, analyse and resolve mechanical energy and matter balances.
  3. Maintain a proactive and dynamic attitude with regard to one's own professional career, personal growth and continuing education. Have the will to overcome difficulties.
  4. Perform a critical analysis of experimental results and of the overall work done.
  5. Students must have and understand knowledge of an area of study built on the basis of general secondary education, and while it relies on some advanced textbooks it also includes some aspects coming from the forefront of its field of study.
  6. Work autonomously.
  7. Work cooperatively.

Lab work report 35 1.4 3, 4, 5, 6
Study 55 2.2 3, 5, 6
Theoretical fundamentals 20 0.8

The fundamental concepts will be presented through videos and teaching material on the Virtual Campus.

The classes will require the active participation of the students who will have to apply the concepts to specific cases and the doubts will be resolved.

Problem classes will be used to solve model problems.

Students will have to study autonomously the reports of equipment description and will have to answer the questions formulated through questionnaires of the virtual Campus

Completion (mostly in class) by students of a numerical detail work of an installation.

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
Block B exam 20 % 2 0.08 1, 2, 5
Equipment selection (multiple choice exams) 10 % 1 0.04 3, 5, 6
Exam block A 20 % 2 0.08 1, 2, 5
Lab work 20 % 1 0.04 3, 4, 6, 7
Numerical work 15 % 1 0.04 1, 3, 4, 7
Seminars 15 % 4 0.16 1, 3, 4, 6, 7

The subject is divided into three parts: part A (topics 1 and 2), part B (topics 3 and 4) and part C (laboratory exercises)

The activities to be evaluated are:

  • A consistent numerical work in designing a simple installation through which a fluid circulates + examination, unrecoverable.
  • Test-type tests on team selection formulated through the Virtual Campus, unrecoverable.
  • 3 Seminars that consist of solving 1 problem, unrecoverable.
  • 2 Partial tests (Ai B)
  • Practices (reports + exam)

The final grade will be calculated according to the expression:

Final grade = 20% test A + 20% test B + 10% tests + 15% numerical work + 15% seminars + 20% practicals.

To pass block A and block B you need to get 50% between the theory exam and the problems, otherwise you will have to recover the block not passed.

Each test will have a theory part and a problem part. Only the problem part will be corrected if a mark greater than or equal to 40% is obtained in the theory part.

To calculate the final grade, you must obtain a minimum of 40% in each of the main items (test A, test B and practicals).

b) Practicals

A notebook is required

The practice block is evaluated as follows: 75% reports, 15% exam, 10% laboratory (behavior in the laboratory, having read the script, attendance, etc.)

To be able to average the practice block, you must get at least a 3 in the exam.
In order to be able to average the practice block, at least a 4 must be subtracted from the average of the reports.
Unexcused absences subtract 1 point from the laboratory grade.
Arriving late unjustifiably subtracts 0.5 points from the laboratory grade.

c) Programming of assessment activities

Evaluable activities will be announced through the Virtual Campus.

d) Recovery procedure

No requirements

e) Qualification review procedure

For each test and retakes, theday, time and place will be indicated when the notes are published.

f) Qualifications

UAB regulations indicate that MH can only be granted to students who have obtained a final grade equal to or higher than 9.00. Up to 5% of MH of the total number of enrolled students can be awarded.

g) Irregularities by the student, copying and plagiarism.

Without prejudice to other disciplinary measures deemed appropriate, irregularities committed by the student that may lead to a change in the grade of an assessment act will be graded with a zero. Therefore, copying, plagiarism, deception, allowing copying, etc. in any of the assessment activities will involve failing it with a zero. Assessment activities qualified in this way and by this procedure will not be recoverable. If it is necessary to pass any of these assessment activities to pass the subject, this subject will be suspended directly, with no opportunity to recover it in the same course.

The copy may be detected during the test, but especially during the correction, so that activity with identical versions will be cancelled.
