ADVANCED MASS TRANSFER - 2019/0

Module code: ENG3187

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.

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 class test , 1 hours  – one class test at 20% value each (LO1, LO2, LO3, LO4, LO5)



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



Formative assessment



None



Feedback



Verbal feedback during Tutorials



Verbal/written feedback from In-semester tests


Module aims

  • To apply the psychrometry fundamentals and the theory of simultaneous heat and mass transfer for gas-liquid, gas-solid, and liquid-solid contact systems
  • To formulate the basic design equations for the unit operations governed by the simultaneous heat and mass processes particularly adiabatic humidification systems, cooling towers, air conditioning systems, and solids driers.
  • To understand the crystal systems and to apply the basic crystallisation theories for designing continuous crystallisers

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 hours per week for 11 weeks (average)

  • Tutorials                                 1.0 hours per every other week: by week 2, 4, 6, 8, 10 and week 11 in class)

  • Independent Learning            9 hours per week for 12 weeks



 



 


Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
