The engineering of chemical reactions
Summary
This course applies concepts from chemical kinetics and mass and energy balances to address chemical reaction engineering problems, with a focus on industrial applications. Students develop the ability to analyze and design chemical reactors of industrial importance.
Content
- Introduction
Profile of Chemical Industry
Chemical Processes
Basics of Chemical Reaction Engineering
Chemical reactions, mole balance equations
Ideal chemical reactors - Reaction kinetics and Rate Laws
Reactant conversion in closed and open systems
Influence of expansion Basic rate laws-formal reaction kinetics
Transformation in closed and open systems
Determination of reaction kinetics
Quasi steady state assumption for complex reaction systems
Homogeneous catalysis / enzyme kinetics - Isothermal Reactor Design-Simple reactions
Batchwise operated stirred tank reactor (BR)
Continuous stirred tank reactor (CSTR)
Plug flow reactor (PFR)
Cascade of CSTR
Combination of PFR and CSTR
PFR with recycling
Semi batch stirred tank reactor - Isothermal Reactor Design-Multiple reactions
Introduction
Parallel reactions, one reactant
Parallel reactions several reactants
- semi-batch reactors
- cross flow reactors
Consecutive reactions
Consecuttive competing reactions - Nonisothermal Reactor Design
Batchwise operated stirred tank reactors
introduction, energy balance
adiabatic reactors
reactor with heat exchange, zero order (Semenov criteria)
- time to maximum rate
- reactor with heat exchange, isoperibolic reactors (n>0)
reactor stability, parametric sensitivity, reactor run-away (n>0)
semi-batch reactors for highly exothermic reactions
Plug-flow reactors
Continuous stirred tank reactors
