To have completed the subjects: Balances in chemical engineering balances, separation operations, heat transfer and chemical reactors.
To be enrolled in the subject control and instrumentation. Level B2 (European reference framework) of Catalan or Spanish.
The planned contents are as follows, but possible restrictions imposed by health authorities may require prioritization or reduction of such contents.
A) Laboratory sessions (supervised activity) 15 sessions of 3 hours, at laboratory Q6/0006.
The presentation of the subject will be held on the first day of the second semester and it is compulsory the assistance. In these 15 sessions, the following experiments are carried out:
1.- Reactors. To study the behavior of an irreversible second-order reaction in ideal chemical reactors (DSTR, CSTR and FPR). To determine the variation of the kinetic constant with the temperature. To analyse the reliability of applying theoretical design equations in an CSTR and PFR.
2.- Distribution of the residence time in reactors. To analyse the real behavior of a system of chemical reactors (CSTR, FPR and CSTR+FPR) from the distribution of residence time (DTR) of each system.
3.- Control. To analyse of the response for both open and closed loop in two processes (temperature and level).
4.- Valves. To study the response of different control valves for different control signals and in different operating conditions. To prepare the characteristic curves for each of the three valves available in the experimental rig.
5.- Heat exchangers with Aspen Exchanger Design and Rating (EDR). Designing a heat exchanger of shell and tubes from the data obtained using the Kern method. To study of different configurations of exchanger.
6.- Rectification. Calculation of the number of plates from the column at total reflux. Checking the equations of Rayleigh and Block. Calculation of the necessary useful power. Calculation of the cooling water needs. Checking the mass balance.
B) Practicalreports (autonomous activity)
Preparation of lab reports based on the data obtained in the laboratory, analysis and discussion of thedata obtained and comparison with the appropriate bibliography, calculation of the propagation of errors and/or sensitivity analysis. Preparation of detailed calculation examples.
The proposed teaching methodology may experience some modifications depending on the restrictions to face-to-face activities enforced by health authorities. It is a compulsory the attendance to the subject due to its hands-on character in the laboratory.
Depending on the number of students, the academic calendar and the number of experimental facilities available, students will be divided into shifts, up to a maximum of 3, and each shift in work teams, up to a maximum
of 10 groups per shift.
Safety measure should be followed all the time. It is extremely important to follow the safety and hygiene rules arising from the exceptional situation of COVID-19 if necessary.
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.
