Download UoS Outline

Unit: CHNG9206: Separation Processes (6 CP)
Mode: Normal-Day
On Offer: Yes
Level: Postgraduate
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: None.
Prohibitions: CHNG2806 OR CHNG5706.
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: Ability to conduct mass and energy balances, and the integration of these concepts to solve real chemical engineering problems. Ability to understand basic principles of physical chemistry, physics and mechanics. Ability to use mathematics of calculus (including vector calculus) and linear algebra, and carry out computations with MATLAB and MS EXCEL. Ability to read widely outside of the technical literature, and to synthesise arguments based on such literature. Ability to write coherent reports and essays based on qualitative and quantitative information
Lecturer/s: Mammucari, Raffaella
Timetable: CHNG9206 Timetable
Time Commitment:
# Activity Name Hours per Week Sessions per Week Weeks per Semester
1 Lecture 2.00 1 13
2 Tutorials/Practical Sessions 2.00 1 13
3 Independent Study 4.00 13
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 4 hours of ‘self-learning’ outside the specified contact periods.

2 Distillation Project* Yes 15.00 Multiple Weeks (As specified by your unit coordinator, 11 pm) 1, 2, 3, 4, 5, 6, 7,
3 Quiz* No 20.00 Week 8 (During your timetabled class) 3, 4, 5, 6,
4 Final Exam* No 40.00 Exam Period 3, 4, 5, 6,
5 Hypothesis testing* No 5.00 Multiple Weeks (As specified by your unit coordinator, 11 pm) 2, 3, 4, 5,
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.
