For the purposes of considering applications for Reasonable Adjustments under the Disability Standards for Education (Cwth 2005) and Students Experiencing Academic Disadvantage Policy, this subject requires all students to actively and safely participate in laboratory activities. Students who feel their disability may impact upon their participation are encouraged to discuss this with the Subject Co-ordinator and the Disability Liaison Unit http://www.services.unimelb.edu.au/disability

AIMS

This subject introduces students to aspects of reactor system design. Chemical reactors are at the heart of any mojor chemical process design. Chemical reaction engineering is concerned with the exploitation of chemical reactions on a commercial scale. Chemical reaction engineering aims at studying and optimizing chemical reactions in order to define the best reactor design. Hence, the interactions of flow phenomena, mass transfer, heat transfer, and reaction kinetics are of prime importance in order to relate reactor performance to feed composition and operating conditions.

This subject is one of the key parts of the chemical and biochemical engineering curriculum upon which a lot of later year material is built.

INDICATIVE CONTENT

1. Kinetics of homogeneous reactions
2. Design of single ideal reactors
3. Multiple reactor systems
4. Other design reactors (recycle reactors and temperature effects)
5. Basics of non-ideal flow
6. Models for Reactors
7. Reactions in model reactors

INTENDED LEARNING OUTCOMES (ILO)

On completion of this subject the student is expected to:

• Interpret data from both ideal and non-ideal batch, plug flow and mixed flow reactors
• Model more complex flowing reactor systems using combinations of idealized plug flow and continuously stirred tank ranks
• Design simple reactor systems
• Predict simple temperature profiles in reacting systems

• One written three hour end-of-semester examination (70%).
• A written 2-hour mid-semester test and two lab reports during the semester (30% in total).

Hurdle requirement: A mark of 40% or more in the end-of-semester examination is required to pass the subject.

Intended Learning Outcomes (ILOs) 1 to 4 are addressed in the examination and the laboratory assignments.

The examination paper will consist of problems designed to test whether the student has acquired the ability to apply fundamental principles to the solutions of problems involving chemical reactors. The problems set for the exam will be similar to those undertaken in the tutorial class.

This subject potentially can be taken as a breadth subject component for the following courses:

• Bachelor of Arts
• Bachelor of Commerce
• Bachelor of Environments
• Bachelor of Music

You should visit learn more about breadth subjects and read the breadth requirements for your degree, and should discuss your choice with your student adviser, before deciding on your subjects.

On completion of this subject students should have developed team work skills and enhance the following generic skills:

• Ability to undertake problem identification, formulation and solution
• Capacity for independent thought
• Ability and self-confidence to comprehend complex concepts, to express them lucidly and to confront unfamiliar problem

LEARNING AND TEACHING METHODS

The subject will be delivered through a combination of lectures and tutorials. Students will also complete two experiments which will reinforce the materail covered in lectures. The two experiments are:

1. CHEMICAL REACTORS
2. DYNAMICS OF REACTORS

CAREERS / INDUSTRY LINKS

The skills gained in this subject are crucial to the career of a process engineer. They will be important for students wishing to progress to jobs in engineering design offices or in operational roles within a wide range of chemical industries including petrochemicals, polymer and surfactant manufacture.
