Objectives

To provide methodology to choose, analyze, design and operate real chemical reactors with emphasis in hydrodinamics, micromixing, energy balances and complex reactions.

Program

Real Chemical Reactors: hydrodinamics, mass/heat transfer, chemical reaction.
Theory of Residence Time Distribution (RTD).
Notions of age, life expectancy and residence time. Distributions of age, 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 mixing. Zwietering equation.
Flow models: axial dispersion and reactors in cascade.
Application of RTD in Chemical Engineering, Pharmacokinetics and environment.

NONISOTHERMAL AND NONADIABATIC REACTORS

Energy balances in batch, CSTR and PFR.
Adiabatic reactors.

REACTOR DESIGN FOR COMPLEX REACTIONS.

Yield and selectivity.

NEW CONCEPTS AND TOOLS TO STUDY CHEMICAL REACTORS

New reactor types (reverse flow, monoliths), multifunctional reactors and CFD.

Teaching methods and learning activities

Classes intend to provide methodology to choose, analyze, design and operate real chemical reactors with emphasis in hydrodinamics, micromixing, energy balances and complex reactions supported by real problems. Practical sessions aim to teach techniques for solving reactor problems including reactor simulation.

Evaluation Type

Distributed evaluation with final exam

Eligibility for exams

According to the General Evaluation Rules of FEUP

Calculation formula of final grade

CF= 0,25 * NT + 0,75 * EF
CF= final grade
NT= grade of the work/project
EF= grade of the final exam

Examinations or Special Assignments

There will be a work/project during the week 10-17 April; this work should be done by groups of 2 or 3 students and its value is 25% of the final grade.

Special assessment (TE, DA, ...)
