Chemical Reactors

Recommended Prerequisites

Mass and Energy Balances, Fluid Dynamics, Heat Transfer, Mas Transfer, Modeling, Simulation and Optimization, Introduction to Reaction Engineering. 

Teaching Methods

The syllabus will be taught in contact lectures with practical examples and discussion of the problems solved by the students. Whenever possible, the resolution of home problems or in classroom will be proposed to studants, aiming to promote a continued study.

Learning Outcomes

Development of competences in the domain of Chemical Reactors Engineering with ideal behavior, aiming the analysis and design of homogeneous reactors, including reactional systems for kinetic parameters determination. The Residence Time Distribution theory will allow the identification of the deviations of the ideal behavior of reactors. These studies will be in line with the new perspectives of Chemical Engineering molecular based, integrating multiscale systems analysis.
