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.
