Valid From: Semester 1 - 2016/17 ( September 2016 )
Module Delivered in 1 programme(s)
Module Coordinator: NIALL MORRIS
Module Author: MICHAEL J O MAHONY
Module Description: This module introduces students to more advanced Process Analysis, including the thermodynamic analysis of power and reverse power cycles, and the analysis of heat exchanger networks through the application of "pinch" technology.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Analyse and solve problems associated with the thermodynamic operation of gas and vapour power cycles, identify the major factors that affect the overall performance of such cycles including the advantages offered by Combined Heat & Power (CHP) cycles.
LO2 Analyse and solve problems associated with the thermodynamic operation of reverse gas and vapour power cycles and then identify the major factors that affect the performance of these cycles
LO3 Apply the concept of Pinch Technology to complex heat exchanger networks and then identify the major factors that affect the overall performance of these networks.
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
None
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.

Requirements

This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.
