Objectives
Development of skills in the design and performance analysis of ideal chemical reactors using mathematical models that integrate reaction kinetics and mass and energy balances. Development of skills in the analysis of the performance of non-ideal reactors through the functions and models of Residence Time Distribution (RTD) Theory.
Program
1. Introduction
1.1. Chemical Reaction Engineering and reactor design.
1.2. Ideal homogeneous reactors. Classification, characterisation and reactor selection.
1.3. The concept of balances: material, energy, overall, macroscopic and microscopic balances.
2. Chemical Reaction
2.1. Quantitative parameters describing the progress of a reaction.
2.2. Fundamentals of chemical kinetics. Methods for determining reaction kinetics.
3. Performance Analysis of Ideal Reactors: Material and Energy Balances
3.1. Continuous stirred-tank reactors. Series of continuous stirred-tank reactors.
3.2. Batch reactors. Residence time and downtime.
3.3. Tubular reactors.
4. Residence Time Distribution Theory RTD
4.1. Main characteristics of the RTD function. Experimental determination of the RTD function.
4.2. Design of non-ideal flow reactors using RTD: complete segregation model, maximum mixedness model, tanks-in-series model and dispersion model.
4.3. Use of computational methods for the application of RTD Theory.
Practical Computational Tasks:
Determination of the Reaction Order.
Determination of the RTD in Continuous Reactors and Prediction of the Conversion to be Achieved.
Evaluation Methodology
The final grade in the continuous assessment period results from the weighting of the mark obtained in a final written test, with a weight of 70 percent, and in the computational practical assignments, with a weight of 30 percent.
The final grade in the final assessment periods results from a written test, with a weight of 70 percent, and from the mark obtained in the computational practical assignments, with a weight of 30 percent.
Students who do not attend at least two thirds of the TP/PL classes effectively delivered, in accordance with the academic regulations in force and except for the cases provided therein, or who do not complete the two computational practical assignments during the contact period, will be excluded from final assessment.
In all assessment periods, in order to pass the course unit, students must obtain a minimum mark of 8 out of 20 in each written test and in each computational practical assignment.
