Objectives

To provide methodological tools to choose, analyze, design and operate real chemical reactors with emphasis on hydrodinamics, micromixing (residence time distribution theory), energy balances and complex reactions.

Learning outcomes and competences

It is expected that students will be able to diagnose the operation of real reactors, and to design non-isothermal reactors and reactors where multiple reactions occur.

Working method

Presencial

Program

Reactor design for complex reactions: yield and selectivity. Nonisothermal and nonadiabatic reactrs. Energy balances in batch, CSTR and PFR. Adiabatic reactors. Strategies for reactors association. New concepts and tools to study chemical recators: reverse flow, film contactors, monoliths, CFD and multifunctional reactors and/or biological reactors.

Real chemical reactors: hydrodynamics, mass/heat transfer, chemical reaction. Theory of Residence Time Distribution (RTD). Notions of age, life expectancy and residence time. Distributions of age, of residence time and intensity function. Tracer methodology: F and C curves of Danckwerts. Relation between RTD and F and C curves. Diagnosis of ill-functioning of reactors. Conversion in real reactors. Total segregation and maximum mixedness. Zwietering equation. Non-ideal flow models: tanks in series and dispersion models. Application of the RTD in Chemical Engineering, pharmacokinetics and environment.

Eligibility for exams

Attending the tests

Calculation formula of final grade

FINAL MARK = (0.1 test 1 + 0.1 test 2 + 0.15 test 3 + 0.65 Exam

Test 1 will focus on topics of 1) reactor design for complex reactions
Test 2  will focus on topics of 2) non-isothermal chemical reactors
Test 3 will focus on topics 3) real chemical reactors (theory of residence time distribution.

The exam will focus on all the topics.

To obtain approval it is necessary to obtain
FINAL MARK > 9.5 and EXAM GRADE > 7

Examinations or Special Assignments

Internship work/project

Special assessment (TE, DA, ...)

By exam.

Classification improvement

Students who wish to do so can improve their classification by exam only once until the appeal period of the academic year following the one in which they passed.

Observations

The final exam lasts 2 hours without consultation (closed book).
