Rio Tinto Alcan in Australia • Rio Tinto Alcan is an integrated aluminium business. Our operations in Australia are: • Weipa Bauxite Mine • Yarwun Alumina Refinery • QAL Refinery (non managed) Weipa Yarwun & QAL
The way we work • Rio Tinto Alcan operations are large energy users. • Management and reduction of energy use is and has always been a priority • Energy costs and emissions are integrated into ‘The way we work’ so as to retain our ‘license to operate’
Energy data collection & analysis • Our existing energy data collection systems include: • Sub metering of electricity and gas for major equipment • Historian database system for process data • Fuel management system • Our existing energy performance and analysis includes: • Daily lean boards for key energy metrics and KPIs • Performance benchmarks • Best practice sharing across sites • Enthalpy models and pinch analysis of Bayer refinery process • To date complying with EEO has added time and costs to our process.
Preparing for KE 3 in an Assessment • Don’t reinvent the wheel • document what you already do • take actions to address the gaps • Compile an ‘Information Pack’ to describes how KE 3 is met • format documents to clearly show how you meet compliance
Developing an Energy Mass Balance • Hold workshops with key personnel in each plant area • Objective is to discuss energy use, data sources and analysis • Workshops gets the team ready for the Idea Generation Sessions. • Our practical approach with EMB data • Good data is essential for management of key energy and materials • used NGER data for site level • Used sub-metering for process level • For completeness, list variables that have a small impact and did not pursue measurements, e.g. waste water
Linking Key Element 3 with Key Element 4 • Ideas to Opportunities • Collate ideas from energy studies e.g. energy audits or pinch analysis, plans and idea hoppers • Idea Generation Sessions • Breakdown of energy use for each process area • Performance benchmarks and data trends • Proportion of fuel use in process area compared to site use • Document the links of KE 3 and KE 4 for compliance
