Level: HE3 Module Co-ordinator: KIRKBY NF Dr (C, C & E Eng)
Number of credits: 10 Number of ECTS credits: 5
Module Availability

Autumn Semester


Assessment Pattern





Two problem sheets as two pieces of coursework assignment based on materials covered in lectures and tutorials




Qualifying Condition(s) 


A weighted aggregate mark of 40% is required to pass the module.



Module Overview
The module develops the understanding 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 and mass transfer with chemical reactions are studied in depth.  
Completion of the progress requirements of Level HE2
Module Aims

To allow the student to study in depth both the fundamental phenomena and its application to the practical design of the contacting equipment:


i)        in which simultaneous heat and mass transfer are the predominant transfer mechanisms


      particularly cooling towers, air conditioning systems and quench towers and solids driers


ii)       in which simultaneous absorption and liquid phase reactions are taking place.


Learning Outcomes

Upon successful completion of the module you will be able to:



i)        demonstrate a sound understanding 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,


ii)       confidently apply the film theory of absorption accompanied with different order reactions to equipment design,


iii)     propose theoretically well founded designs for cooling towers, quench towers, solid drying equipment, air conditioning units and absorption towers with chemical reaction.
