Aims

The unit aims to:

  • Provide understanding to allow the selection of separation operations based on factors involving the feed and product property differences.
  • Allow students to quantitatively design key separation processes.
  • Provide students with knowledge on liquid-liquid extraction design.
  • Analyse and design multicomponent distillation sequences
  • Extend student knowledge of distillation to include the separation of azeotropic systems.

Learning outcomes

ILO 1:Classify separation processes by type and select suitable separations for mixtures based on the properties of the components.

ILO 2: Design liquid-liquid extraction columns for ternary systems using the Hunter-Nash method.

ILO 3: Calculate the approximate design of multi-component distillation columns using short-cut models.

ILO 4: Assess simple and complex distillation column sequences using heuristic rules to find the optimal options.

ILO 5: Construct azeotropic distillation sequences using residue curve for ternary systems.

Teaching and learning methods

Lectures provide fundamental aspects supporting the critical learning of the module and will be delivered as pre-recorded asynchronous short videos via our virtual learning environment.

Synchronous sessions will support the lecture material with Q&A and problem-solving sessions where you can apply the new concepts. Surgery hours are also available for drop-in support.

Feedback on problems and examples, feedback on coursework and exams, and model answers will also be provided through the virtual learning environment. A discussion board provides an opportunity to discuss topics related to the material presented in the module.

Students are expected to expand the concepts presented in the session and online by additional reading (suggested in the Online Reading List) in order to consolidate their learning process and further stimulate their interest to the module.

Study budget:

  • Core Learning Material (e.g. recorded lectures, problem solving sessions): 24 hours
  • Self-Guided Work (e.g. continuous assessment, extra problems, reading)     : 44 hours
  • Exam Style Assessment Revision and Preparation: 32 hours
