REFINERY SEPARATION PROCESSES - 2020/1
Module code: ENG3199
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
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, ultra-filtration and adsorption.

|Assessment type||Unit of assessment||Weighting|
|School-timetabled exam/test||Class Test 1 (45 minute test on multicomponent equilibrium)||10|
|School-timetabled exam/test||Class Test 2 (45 minute test on multicomponent separation)||10|
|Examination||Examination (2 hours)||80|
New examination and class tests.
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:
- Class Tests – 20%, 2x45 minute (10% each test), (LO1, LO3)
- Examination – 80%, 2 hours (LO1, LO2, LO3, LO4)
Verbal feedback during tutorial sessions and the optional drop-in sessions, written feedback from Class Tests.
- 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.

Tutorial Hours: 6
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:
- Lectures 4 hours per week for 11 weeks (average)
- Tutorials 0.5 hour per week for 12 weeks (average)
- Class Tests 2 x 0.75 hours (nominally in weeks 6 and 11)
- Independent Learning 98.5 hours in total (8.21 hours per week for 12 weeks (average))
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.
