Prerequisites
Minimum knowledge required to take the subject:
Differential and integral calculus (baccalaureate level)
Linear algebra (baccalaureate level)
It is recommended to take the propedeutic courses if you do not have the required level
Objectives and Contextualisation
The objectives of the course are first of all that the student acquires the basic concepts that are related to carry
out an industrial process and then familiarize with the mathematical tools that will be the starting point for the
analysis of processes.
During the first semester, the study of matter and energy balances, which are the most frequently
performed by a chemical engineer throughout his professional life, is carried out.
During the second semester an introduction to transport phenomena that govern the unit operations processes is carried out.
Competences
- 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
- Apply and identify basic concepts related with chemical engineering.
- Apply and identify the macroscopic equilibrium of momentum.
- Apply and identify velocity equations in molecular transport.
- Develop independent learning strategies.
- Identify, analyse and resolve balances of energy in simple chemical processes.
- Identify, analyse and resolve balances of matter in a stationary or non- stationary state, with or without a chemical reaction, in simple chemical processes.
- Obtain and apply the design equations for ideal isothermal reactors.
- 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.
- Work cooperatively.

Methodology
Theory classes: One group. Confirm days and classrooms for each group on the school website.
Problem classes: Students are divided into two groups. Confirm days and classrooms for each group on the school website. A list of problems and solutions for each teme will be published on the virtual campus. Problems solving will be done in class and problems will be proposed to be solved by the students.
Seminars: Students are divided into two groups. Confirm the days and classrooms of each group on the school website. Reinforcement of theory and problems. Problems and practical questions may be proposed to solve in class, and they will be delivered at the end of the class.
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
Continuous evaluation:
· partial tests (90% of the total note)
1st partial test: Temes 1, 2 and 3. (30% note).
2nd partial test: Teme 4 and 5. (30% note).
3rd partila test: Temes 6,7 and 8. (30% note).
These tests will consist of theory questions and problem solving. For the part of problems you can consult class notes and books, but not solved problems neither of class nor of books of collections of problems.
Minimum score of each part to pass the continuous assessment 3/10.
· Work delivered in Seminars: 10% note. The student is responsible of the returned work. The student should keep the original work untill the end of the course, to solve possible errors in case it is necessary.
Retaking final test:
The students who do not pass the subject by continuous evaluation (5/10), can ratake only the partial tests failed (note under 5/10).
The retake test of each partial test will account the same percentage than in continuous evaluation. The notes of the passed partial tests are maintaned, as well as the seminaris note.
Students that passed the subject by continuous evaluation can not attent the retaking test to increase the mark.
Exam dates: School web and/or Campus virtual
To pass the subject a 5/10 note is necessary
In no case will exams (evaluation tests) be carried out on days and times different from those officially
published in the School Web
Important observation: Without prejudice toother disciplinary measures deemed appropriate, and in
accordance with current academic regulations, will be scored with a zero theirregularities committed by the
student that may lead to a variation of the rating of an evaluation act . Therefore, plagiarizing, copying or
allowing an evaluation activity to be copied, or falsifying any evaluation activity will imply suspending with a
zero and can not be recovered in the same academic year. If thisactivity has a minimum associated grade,
then the subject will be suspended.
Qualification review procedure
For each evaluation activity, a place, date and time of revision in which the student can review the activity with
the teacher will be indicated. In this context, claims may be made on the activity grade, which will be evaluated
by the faculty responsible for the subject. If the student does not appear in this review, this activity will not be
reviewed later.
Qualifications
Honor plates. Granting a grade of honor registration is the decision of the faculty responsible for the subject.
The regulations of the UAB indicate that MH can only be granted to students who have obtained a final grade
equal to or greater than 9.00. You can grant up to 5% of MH of the total number of students enrolled.
A student will be considered not evaluable (NA) if he has not been presented in a set of activities the weight of
which equals a minimum of two thirds of the total grade of the subject.
