Module overview

This course provides an introduction to separation processes in general, but with particular emphasis on equilibrium staged separations of binary mixtures.  Processes covered include binary distillation, liquid-liquid extraction and gas absorption and desorption in tray columns. This gives students an appreciation of what lies beneath chemical engineering flow-sheeting and design software packages. This appreciation is enhanced by hands on experience with HYSYS, an industry standard chemical engineering design simulation package.

Module aims

Provide students with an introduction to equilibria, including binary vapour-liquid systems and ternary liquid-liquid systems.

Introduce equilibrium staged separation processes, focussing on gas absorption, binary distillation and liquid-liquid extraction processes.

Provide the knowledge and skills to undertake the specification and design of absorption columns, binary distillation columns and liquid liquid extractors (i.e. continuous diffusional contact devices)

Familiarise students with a commercially available process modelling package (HYSYS) through hands-on examples

Methods of Teaching / Learning

The learning and teaching strategy is designed to:


Illustrate fundamental concepts and design procedures during lectures, by presenting them in the context of several worked examples.
Highlight the similarities and differences between the different separation processes, and their design.
Provide the students with opportunities to practice these concepts in carefully selected and thoroughly supervised tutorial sessions.
Allow students to develop hands-on experience of building and analysing complex process models


The learning and teaching methods include:

Separation Processes 1


Lectures                                 2 hours per week for 11 weeks
Tutorial/Problem Classes       1 hours per week for 12 weeks (12 hours total) 
Independent learning             82 hours


HYSYS


Supervised Lab Session        4 hours (2 sessions of 2 hours)
Independent study                30 hours      


 

Assessment Strategy

The assessment strategy is designed to engage the students at an early stage in the semester and provide students with the opportunity to demonstrate all module learning outcomes, through a balanced mix of theoretical questions, design exercises and hands-on HYSYS simulations.

Thus, the summative assessment for this module consists of:

·         Examination – 50%, 2 hours (LO1 – LO3)

·         Coursework – 20%, on the material covered in the first eight lectures, namely equilibria, absorption and stripping. (LO1 – LO3), 1 week for completion

·         HYSYS Report – 30%. Submission of a 2000 word (excluding appendices) report, outlining the modelling of the process and including an assessment of the profitability of the process and a critical evaluation of the design of the process, two weeks after the lab session (LO3, LO4, LO5)

Formative assessment

·        Submission after first HYSYS session (Simulation, Report and Simple Calculations)

 

On successful completion of this module, students will be able to:


Recognise models used to describe phase equilibirum in ideal mixtures and useful simplifications for non-ideal cases. (LO1 – C, K)
Predict equilibria for binary vapour-liquid and ternary liquid-liquid systems and interpret appropriate graphical representations of these equilibria. (LO2 - C, K)
Design stage processes for gas-liquid absorption (bulk and dilute), binary distillation and liquid-liquid extracion using equilibria, operating and tie lines. (LO3 - C, K, P)
Interpret a process description anduse HYSYS to simulate a process. (LO4 – K, T, P)
Critically evaluate the output of the simulation and apply a simple costing model to evaluate the profitability of the process (LO5 – C, T, P)
