Objetivos

The aim of this curricular unit is to present topics of intermediate and advanced level for the selection and sizing of different types of reactors ideal and real. After completed this curricular unit, students should have able to identify important parameters in the selection criteria of chemical reactors and measure different types of reactors, calculate time and spatial distribution of residence time in chemical reactors and determining the causes for deviation to the ideal behavior of the reactors.

Programa

1. Introduction to chemical reactors.
2. Energy balance of a chemical transformation. Kinetics. Half-life time. temperature influence.
3. Selection criteria of reactors. Main features of a reactor. Homogeneous, discrete and continuous reactors. Different types of reactors comparison. Material and energy balance formulation. Residence time and space time. Stirring design and classification.
4. Material and energy balances, characteristic equation, scaling under isothermal, adiabatic and industrial applications: a) single-phase batch reactors in the transient regime. b) continuous tubular reactors. c) continuous stirred tank reactors (CSTR). Association in series of continuous reactors.
5. Distribution of residence times. Deviations causes from the ideal behavior of the reactor RTD function for PFR and CSTR reactors in series. Reactors with the RTD function design, segregation model, maximum mixing model.

Métodos de ensino e atividades de aprendizagem

These basic contents to be rigorously apprehended by students must be taught in a solid and consistent manner, requiring that the basic concepts be explained properly. Consequently it is necessary that these contents be taught by exhibition in theoretical classes.


Distance Learning:
Classes by Videoconference (Zoom/Colibri) in the weekly schedule for the Curricular Unit. Recorded exhibition using the powerpoint of the concepts (made available in moodle). Application in the virtual classroom, in the resolution of exercises with the support of a whiteboard through the XODO tool (which will work on a Tablet, in aid of the PC) and thus allows a more understandable writing.Classes of doubts in a "distance" context will be ensured at the time of doubts that was already scheduled, so that it does not interfere with the schedule of the remaining UC . With the option that they have always been given to send questions by emails, with photo of their resolution, for example.
