The subject “Chemical Reactors” is one of the two subjects, together with “Mass Transfer”, that justify the specific flavor of “Graduate in Chemical Engineering” as a unique career differentiated from other Graduates in Engineering that provide the habilitation for the Industrial Technical Engineer profession.
The objective of this subject is to provide knowledge about industrial-scale chemical reactors analysis and design. It is also intended this subject to be a practical field which the students can apply in the knowledge acquired in the previous 3rd course subject “Chemical Reaction Engineering".
Work in group, use of software for problem solving (Excel and Hysis) will be promoted, so as the use of virtual course (Moodle).
The contents of this subject include:
Non-isothermal reactors. Stability. Non-ideal behaviour of chemical reactors. Dispersion and tank-in-series models. Non-isothermal reactors. Combined models. Catalytic and heterogeneous reactors. Rate-limiting step. Case studies.

The culture of safety will be promoted, making special emphasis on the stability of the reactors.
Scenario 1:
The teaching methodology includes lectures for the presentation of the theoretical part of the subject and resolution of some of the proposed problems. In the seminars, students will solve proposed problems, individually or in groups of 2 students, using an Excel spreadsheet when necessary. Alternatively they will take continuous assessment tests of the subject.
There will be two group tutorials in which students will work on solving an open-ended problem that they will have to solve in groups. After the corresponding personal work, in the second tutorial they will present the solution they propose for it.
In the Computer Room sessions (6 h), chemical reactor problems will be solved using Aspen-Hysys. In the last session an evaluation test will be carried out.
A technical visit to an industrial-scale plant will be performed if funding is available.
The Virtual Campus will be used as a repository for the documentation of the subject and as an additional means of teacher-student communication. The presentations of the topics used in the lectures as well as the corresponding problem relationships will be provided to the students in advance.
The list of the methodologically proposed activities and the skills to be developed is as follows:
- Master classes: CG3, CG4, CQ1, CQ2
- Seminars: CG4, CT4, CT6, CT8, CT13
- Computer room: CT4, CT6, CT13, CQ1, CQ2
- Group tutorials: CG4, CQ1, CT1, CT4, CT6, CT8, CT10, CT13, CT19
Scenario 1:
Students will take a mandatory exam, complementing the continuous assessment, with theoretical questions and problem solving. The qualification will be distributed as follows:
a) Exam: 70%
b) Group tutoring: 7.5%.
c) Seminars: 7.5%
d) Practices in the computer room: 15%
To pass the subject, students must achieve a minimum grade of 4 points (out of 10) in the exam.
Continuous assessment grades will be communicated to the student before the exam.
On the second opportunity, the grades obtained in sections b), c) and d) are kept.
If a student participates in continuous evaluation activities (group tutorials, seminars or practicals) in a percentage higher than 20%, it will be considered as presented in the two evaluation opportunities of the course.
In cases of fraudulent completion of exercises or tests, the provisions of the Regulations for the evaluation of the academic performance of students and the review of grades will apply.
Assessment of competences:
Exam: CQ1, CQ2, CG3, CG4, CT1, CT6, CT13, CT19
Tutoring: CQ1, CG4, CT1, CT4, CT6, CT8, CT10, CT13, CT19
Seminars: CG3, CG4, CT1, CT4, CT8, CT10, CT13, CQ1, CQ2

The Virtual Campus will be used.
Software used: Excel and Aspen-Hysys.
The subject will be taught in Spanish / Galician.
Contingency plan:
Methodology:
Scenario 2: mixed teaching (preferentially face-to-face)
The lectures will be non-face-to-face and will be carried out by videoconference through MsTeams synchronously at the time established for the subject.
The seminar and computer classroom classes will be face-to-face, complying with the distancing and security measures imposed by the USC (use of a mask and hydrogel).
The compulsory group tutorials will be carried out in a non-face-to-face way, preferably through Ms Teams.
The tutorials can be done in a non-face-to-face way through MsTeams, in the classroom of the subject.
Scenario 3: non-face-to-face teaching
Both the lectures, as well as the seminars and tutorials will be carried out in a non-face-to-face way. The first two will take place through synchronous telematic teaching by Ms Teams, while the tutorials can be carried out asynchronously, both in MsTeams and in the Virtual Classroom.
Assessment system
Scenario 2: mixed teaching (preferentially face-to-face)
a) Exam: 70% (face-to-face)
b) Group tutoring: 7.5%
c) Seminars: 7.5%
d) Practices in the computer room: 15%
Scenario 3: non-face-to-face teaching
a) Exam: 60% (synchronous telematics)
b) Group tutoring: 10%.
c) Seminars: 15%
d) Practices in the computer room: 15%
Recommendations for telematic teaching:
• It is necessary to have a computer with a microphone and a camera to carry out the telematic activities scheduled throughout the course. The acquisition of equipment with an MS Windows environment is recommended, since other platforms do not support some of the computer programs used in the subjects, available at USC.
• Improve informational and digital skills with the resources available at USC.
The mask must be used during the student's stay at the Center. Scrupulously follow all the indications of the health authorities and the USC itself, for the protection of health from Covid-19. Wear a mask, apply hydrogel or wash your hands with soap and water following the instructions and when possible, increase the distance with the rest of the classmates and teacher in the classroom.
