Summary of Module

This module aims to give students of the chemical engineering degrees a broad appreciation of several separation processes that are key to the process industry.

The separation processes studied here are:

  • Evaporation (including single- effect and multi-effect evaporators, boiling point rise , and other designs for energy saving, such as vapour recompression and vacuum operation, with basic economic analysis).
  • Crystallisation.
  • Binary and multicomponent distillation in continuous mode, including vapour/liquid equilibrium (VLE), Gibbs' phase rule, bubble and dew point calculations for ideal and non-ideal mixtures,  the use of the isothermal flash equation, and shortcut and rigorous distillation calculations.
  • Various solid separation processes, including sedimentation, elutriation, and centrifugation, and thickening.
  • Membrane separations.
  • Mixing of liquids examines the calculation of power requirements of mixers via dimensionless analysis, the use of baffles and choice of impellers.

During the course of this module students will develop their UWS Graduate Attributes ( ). Universal: Academic attributes - critical thinking and analytical & inquiring mind; Work-Ready: Academic attributes - safe laboratory working; Successful : autonomous, driven and resilient.

Module Delivery Method
Face-To-FaceBlendedFully OnlineHybridCHybridOWork-based Learning
check mark

Term used to describe the traditional classroom environment where the students and the lecturer meet synchronously in the same room for the whole provision.

A mode of delivery of a module or a programme that involves online and face-to-face delivery of learning, teaching and assessment activities, student support and feedback. A programme may be considered “blended” if it includes a combination of face-to-face, online and blended modules. If an online programme has any compulsory face-to-face and campus elements it must be described as blended with clearly articulated delivery information to manage student expectations

Fully Online
Instruction that is solely delivered by web-based or internet-based technologies. This term is used to describe the previously used terms distance learning and e learning.

Online with mandatory face-to-face learning on Campus

Online with optional face-to-face learning on Campus

Work-based Learning
Learning activities where the main location for the learning experience is in the workplace.

Campus(es) for Module Delivery

Learning and Teaching
This module covers a wide variety of theoretical, conceptual and practical areas, which require a range of knowledge and skills to be displayed and exercised. Delivery of its syllabus content therefore involves a diversity of teaching and assessment methods suitable to the learning outcomes of the module; these include formal lectures, structured tutorials (work closely integrated with the lecture material), laboratory exercises to develop practical skills and familiarisation with equipment and experimental techniques, industrial process plant visit trip, completion and submission of written and oral coursework making use of appropriate forms of IT and VLE, and independent study.
Learning Activities
During completion of this module, the learning activities undertaken to achieve the module learning outcomes are stated below:
Student Learning Hours

Assessment: (also refer to Assessment Outcomes Grids below)
Assessment for the module includes both formative and summative assessment.

Formative assessment is provided during lectures in the form of class exercise problems, during tutorial sessions, during laboratory sessions and as part of the preparation for written submissions.

Summative assessment will be based on the following: (a) final written exam worth 50% of the final mark, and
(b) continuous assessment worth 50% of the final mark.
The continuous assessment component in this module will consist of the following elements: (i) written assignment worth 25% of the final mark, (ii) laboratory reports worth 25% of the final mark
Further details, and the academic calendar when assessment is likely to feature, will be provided within the Module Information Pack.
