CHNG2806: Separation Processes (2020 - Semester 2)
| Unit: | CHNG2806: Separation Processes (6 CP) |
| Mode: | Normal-Day |
| On Offer: | Yes |
| Level: | Intermediate |
| Faculty/School: | School of Chemical and Biomolecular Engineering |
| Unit Coordinator/s: |
Dr Ghadi, Amirali
|
| Session options: | Semester 2 |
| Versions for this Unit: |
| Campus: | Camperdown/Darlington |
| Pre-Requisites: | CHNG1103 AND CHNG2803. |
| Brief Handbook Description: | This unit will cover the general principles and the development of quantitative models of separation processes based on equilibrium and rate processes. Concepts of phase equilibria, transport phenomena and mass and energy balance will be used to model the separation units. Understanding of these principles will provide the basis for analysis and preliminary design calculations of large scale separation units of importance to manufacturing industries. The principles will be applied to units operations of distillation (binary, multicomponent), solvent extraction, absorption, adsorption and membrane processes |
| Assumed Knowledge: | It is assumed that students will be concurrently enrolled in or have already completed CHNG2804 or equivalent |

| T&L Activities: | Tutorial: After each lecture on Monday, students will be given homework/tutorial questions relevant to the lecture materials. There will be a 2-hour tutorial on the following Thursday where students will work on the questions with the help of the lecturer and the tutors. To increase the effectiveness of the tutorial sessions in achieving deep understanding of the key concepts, students are encouraged to attempt these questions prior to attending the tutorial session. Each homework should be submitted before the following Monday. Project/laboratory: Students will work on a group-based project regarding optimisation of a distillation column starting from week 6. Students in allocated groups will carry out a comprehensive study including design of experiment (DOE), mass and energy analyses, computer simulation and hands-on experimentation on a lab-scale distillation column to validate the simulation data. Independent Study: Students are expected to spend about 6 hours of ‘self-learning’ outside the specified contact periods. |
Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.
(8) Professional Effectiveness and Ethical Conduct (Level 2)
1. Adopt good laboratory practice in conducting and reporting laboratory experiments.
(7) Project and Team Skills (Level 2)
2. Work creatively and systematically with others in ensuring correct procedures and accurate results.
(4) Design (Level 2)
3. Understand the principles for designing separation units
4. Skills in operation and assessment of separation unit performance
(2) Engineering/ IT Specialisation (Level 2)
5. Understand the general principles involved in separation processes based on equilibrium and transport phenomena

| Assessment Description: |
* indicates an assessment task which must be repeated if a student misses it due to special consideration Tutorial Exercises/homework: There will be 8 take-home assignments. Students will work on the homework questions during the tutorial sessions with the help of the lecturer and the tutors for better understanding the key concepts of the lectures Project/Lab Practical: There will be one group-based project/laboratory session on operation and simulation of a distillation column Quiz: One mid-semester quiz on week 8 covering the topics of membrane and liquid-liquid extraction Final Exam: Final examination during exam period Hypothesis testing: All individual students are required to form and submit a hypothesis/prediction about the outcome of the project before starting the Distillation Project. You will then need to submit your reflection on your original hypothesis/prediction at the end of the project. You will lose the whole allocated mark if you only submit one of the tasks. That is to say, both the ``original hypothesis/prediction`` and ``reflection`` tasks must be submitted. |
