REFINERY SEPARATION PROCESSES - 2022/3
Module code: ENG3199
In light of the Covid-19 pandemic the University has revised its courses to incorporate the ‘Hybrid Learning Experience’ in a departure from previous academic years and previously published information. The University has changed the delivery (and in some cases the content) of its programmes. Further information on the general principles of hybrid learning can be found at: Hybrid learning experience | University of Surrey.
We have updated key module information regarding the pattern of assessment and overall student workload to inform student module choices. We are currently working on bringing remaining published information up to date to reflect current practice during the academic year 2021/22.
This means that some information within the programme and module catalogue will be subject to change. Current students are invited to contact their Programme Leader or Academic Hive with any questions relating to the information available.
Multicomponent separation is the most commonly used industrial separation process and a sound understanding of the fundamental principles (material/energy balances, vapour-liquid, liquid-solid, gas-solid and liquid-liquid equilibrium, separation efficiency and system hydrodynamics) defining the operation of such processes is essential to a graduate engineer. This module extends a students knowledge and understanding to include multicomponent systems involving distillation and adsorption.

|Assessment type||Unit of assessment||Weighting|
|Examination||2 HOUR INVIGILATED EXAM||80|
The assessment strategy is designed to provide students with the opportunity to demonstrate their knowledge and analytical skills over the full range of module material and to encourage progressive learning.
Thus, the summative assessment for this module consists of:
- Coursework - 20% (LO1, LO3)
- Examination – 80%, 2 hours (LO1, LO2, LO3, LO4)
Formative assessments will include:
- A revision of pre-requisite knowledge from previous modules at the start of the semester
- Exam-style short questions during the semester to test ongoing knowledge and to practice exam technique.
Verbal feedback during tutorial sessions, written feedback on the coursework.
- a systematic appreciation and critical awareness of the importance of component separation to the process industry
- a comprehensive appreciation of the characteristics of the separation of ideal and non-ideal multicomponent systems using a variety of techniques
- an in-depth appreciation of the inter-relationships between the separation performance and operating parameters of multicomponent separating devices
- a knowledge of the design methodologies of multicomponent distillation columns
- an appreciation of the effects of hydraulic malfunction on separation efficiency and the ability to propose feasible scenarios of malfunction based on operating data
- prepare a scoping design and initial sizing of some separation operations of fluid/solid and biological systems, based on adsorption, and membranes.

Methods of Teaching / Learning
The learning and teaching strategy is designed to:
- Take students logically through the challenging material associated with complex multicomponent multiphase separation.
- To ensure a logical and progressive learning experience
- To allow students to practice their skills on a series of real life tutorial problems in a supportive environment.
The learning and teaching methods include:
- Independent Learning
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
