Engineering internship final report: Alcoa World Alumina
Correia, Isaac (2008) Engineering internship final report: Alcoa World Alumina. Internship Report, Murdoch University.
This report covers the work undertaken during the internship at Alcoa's Wagerup refinery performed throughout the period of 11th August to 5th November 2008. The report will cover the work conducted during the internship, primarily focusing on the main project. The aim of the project was to conduct a performance of all control loops, instrumentation and code in precipitation and fix issues where possible in preparation for the implementation of an advanced controller.
The project was split into two parts, the software review which involved the analysis of all necessary programs and a loop analysis to analyse the performance of the controllers using performance indices such as rise time, settling time, decay ratio and Integral Square Error (ISE). Saturation time and mode analysis was also required and the incorporation of the valve characteristic plot allowed for an effective way to detect instrument problems such as valve stiction. The review has so far covered 90% of all the necessary loops required to be analysed. Of those analysed so far over 65% exhibited less than satisfactory performance
