Module overview

The module is designed to develop a student’s applied analytical skills and knowledge of the complex mass transport phenomena in selected types of liquid/gas, solid/gas and liquid/solid/gas contact equipment commonly encountered in chemical process plants. The complexity of the design procedure is covered with selected process examples in which simultaneous heat and mass transfer, mass transfer with chemical reactions and physical fluid/particle separation are studied in depth.

Module aims

simultaneous heat and mass transfer are the predominant transfer mechanisms particularly cooling towers, air conditioning systems and quench towers and solids driers.

simultaneous absorption and liquid phase chemical reactions are taking place.

particles must be separated from the fluid in which they are suspended.

Learning outcomes

Attributes Developed
1 Demonstrate a sound grasp of psychrometry, the theory of simultaneous heat and mass transfer for gas-liquid and gas/solid contact systems based on interfacial film, transport and phase equilibria and specific flow configurations of the contact equipment, confidently apply the film theory of absorption accompanied with different order chemical reactions to equipment design.        KCP
2 Propose theoretically well-founded designs for cooling towers, quench towers, solid drying equipment, air conditioning units and absorption towers with chemical reaction.  KCP

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

Allow students to develop the necessary skills and knowledge to fulfil the module learning outcomes
Allow students to practice applying their learning to selected tutorial problems in a supportive environment and in so doing develop further their skill base
Allow students to solve some real world design problems

The learning and teaching methods include:

Lectures                                 3.5 hours per week for 11 weeks (average)
Tutorials                                 1.0 hours per week for 12 weeks
Independent Learning               8.3 hours per week for 12 weeks



Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate that they have met the module learning outcomes through

·         Successfully completing the In-semester tests on which they will receive effective feedback

·         Applying their skills to the demanding set of Tutorial problems where again providing effective guidance and feedback is considered critical to their learning

·         Completing the final examination.

Thus, the summative assessment for this module consists of:

·         In-Semester test in Solid/Fluid Separations – two at 10% each (LO1, LO2, LO3, LO4, LO5)

·         Examination – 80% (two sections), 2 hours, (LO1, LO2, LO3, LO4, LO5)

Formative assessment



Verbal feedback during Tutorials

Verbal/written feedback from In-semester tests
