CHEMICAL ENGINEERING THERMODYNAMICS - 2018/9
Module code: ENG2122
This module addresses the essential concepts of Chemical Thermodynamics that are required by Chemical Engineers. Starting from the fundamental laws of thermodynamics, the course builds up to the prediction of equilibrium states for complex reaction mixtures, and vapour-liquid systems that exhibit non-ideal behaviour.
Applied Thermodynamics: This section of the module extends the material covered in the introductory lectures at FHEQ Level 4. Specifically, the use of the First and Second Laws of Thermodynamics to analyse and design simple power and refrigeration cycles is introduced.

|Assessment type||Unit of assessment||Weighting|
|Examination||EXAMINATION (2 HOURS)||80|
|Coursework||COURSEWORK (CHEMICAL ENGINEERING THERMODYNAMICS)||20|
The assessment strategy is designed to provide students with the opportunity to demonstrate the full range of learning outcomes though the balanced mixture of lecture and tutorial/problem classes coupled with the carefully grades tutorial problems which reflect current industrial practice.
Thus, the summative assessment for this module consists of:
· Examination – 80%, 2 hours (LO1 – LO5)
· Coursework – 20% (L01-L05)
· Open-book class test, 45 minutes (Chemical Thermodynamics) (LO1, LO2)
· Online multiple choice self tests (LO4, LO5)
· HYSYS worksheets for the demonstration of some key Chemical Thermodynamics concepts (LO3, LO4, LO5)
· Weekly verbal feedback during tutorial classes (LO1 – LO5)
· Verbal feedback during optional drop-in tutorial classes (LO1 – LO5)
- Provide students with a solid foundation in Chemical Thermodynamics that will enable interpretation and prediction of a range of chemical and physical transformations such as phase changes and chemical reactions, and to underpin and support the associated work in Reaction Engineering and Separation Processes courses.
- Provide and consolidate understanding and ability to apply the First Law of Thermodynamics to a wide variety of engineering problems
- Develop a firm grounding in the thermodynamic property of entropy and its use in the analysis of simple processes and cycles including the use of isentropic efficiency.

Methods of Teaching / Learning
The learning and teaching strategy is designed to:
Carefully cover in lectures the necessary fundamental material for Chemical and Applied Thermodynamics, and demonstrate concepts with appropriate (and where possible practical) examples.
Allow students adequate time to consolidate learning of Chemical Thermodynamic concepts using a large number of carefully selected tutorial problems and regular formative assessment.
The learning and teaching methods include:
Lectures 3 hours per week for 11 weeks
Tutorials 1 hour per week for 11 weeks
Independent learning 8.8 hours per week for 12 weeks (average)
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.
