Description

Reaction engineering deals with the performance analysis and design of equipment for carrying out chemical reactions. The analysis involves principles of chemical kinetics, thermodynamics, heat and mass transfer as well as fluid mechanics. In this unit the basic principles of chemical kinetics and reaction equilibrium are covered, and then various ideal reactors in which the complexities arising from resistances associated with fluid flow as well as heat and mass transfer are sequentially introduced. Both homogeneous as well as heterogeneous catalytic systems are considered.

Prerequisite Rule

Students must pass 2 units from ENS2160, ENS3110

Learning Outcomes

On completion of this unit students should be able to:

  1. Calculate the conversion for an ideal isothermal reactor starting from a general mass balances.
  2. Calculate the impact of changing solid (or fluid) properties on the conversion of a heterogeneous reaction.
  3. Calculate the thermodynamic limit of a given reaction at given conditions.
  4. Combine mass and energy balances to calculate the conversion in an ideal non-isothermal reactor.
  5. Formulate a residence time distribution from tracer experiment results and use it to predict conversion in a non-ideal reactor.
  6. Identify the mechanisms involved in a heterogeneous reaction and formulate an effective rate equation.
  7. Specify/design the configuration of a reactor to achieve optimal fluid flow, mixing, heat transfer and mass transfer for a given reaction(s).
  8. Write reaction rate equations for common types of homogeneous and heterogeneous reactions.

Unit Content

  1. Analysis and design of batch reactors.
  2. Catalysis and heterogeneous reactors: analysis of reaction rates in single catalytic particles and the design of catalytic reactors.
  3. Isothermal flow reactors and non-ideality: design and behaviour.
  4. Non-ideal reactor behaviour: mixing and residence time distributions.
  5. Non-isothermal chemical reactors: energy balances and temperature changes.
  6. Plug-flow and continuous stirred tank reactors.
  7. Reaction equilibrium, rates and stoichiometry.
  8. The chemical reactor and the concept of reaction rate.

Additional Learning Experience Information

Assignment-based learning, tutorials and group based laboratory work.

Disability Standards for Education (Commonwealth 2005)

For the purposes of considering a request for Reasonable Adjustments under the Disability Standards for Education (Commonwealth 2005), inherent requirements for this subject are articulated in the Unit Description, Learning Outcomes and Assessment Requirements of this entry. The University is dedicated to provide support to those with special requirements. Further details on the support for students with disabilities or medical conditions can be found at the Access and Inclusion website.

Academic Misconduct

Edith Cowan University has firm rules governing academic misconduct and there are substantial penalties that can be applied to students who are found in breach of these rules. Academic misconduct includes, but is not limited to:

  • plagiarism;
  • unauthorised collaboration;
  • cheating in examinations;
  • theft of other students' work;

Additionally, any material submitted for assessment purposes must be work that has not been submitted previously, by any person, for any other unit at ECU or elsewhere.

The ECU rules and policies governing all academic activities, including misconduct, can be accessed through the ECU website.
