Carnac identified a high-value Greenhouse Gas (GHG) reduction opportunity for an alumina refinery. Carnac were subsequently engaged to complete a Pre-Concept Study for technical validation of the opportunity.
Carnac were engaged to assess the operating limits of an alumina refinery in relation to its environmental licence restrictions.
Carnac’s assessment was successful in providing the client with a go-forward strategy to improve the operation’s return on investment whilst ensuring environmental limits are adhered to.
Carnac identified several cost reduction opportunities for an alumina refinery via the completion of a Maximum Technical Capability Assessment (debottlenecking study). Carnac further developed the opportunities at a concept level and selected which opportunity to take forward for a prefeasibility study.
Carnac was engaged to investigate events associated with the bursting of heat exchanger tubes and identified root-cause of failures.
Carnac were engaged to review the existing head chute and rock box design and provided a concept of new rock boxes and Apron Feeder Skirts. Discrete Element Modelling (DEM) was used to develop and assess rock box remediation options. Carnac also provided engineering design for the removal and relocation of conveyor idlers and support structures and delivered Issued for Construction (IFC) drawings for all remediation works.
