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 undertook a debottlenecking study and provided plant improvement recommendations for an existing Tailings Liquor Treatment Plant at an Alumina Refinery.

Carnac undertook an options assessment for the logistics, supply, and handling of a tailings liquor treatment reagent for an Alumina Refinery.

Carnac performed a Concept Study to understand the impact of future bauxite ore variations at an alumina refinery. Carnac assessed the impact on both current and future operations (following planned plant upgrades).

Carnac identified several high-value opportunities for an alumina refinery that would help the client gain a competitive advantage in the alumina market. One opportunity identified involved recovering reagent from a spent liquor stream. The opportunity was developed by Carnac from a concept to feasibility study level.

Carnac Project Delivery Services (Carnac) was engaged by the client to conduct an assessment of the current High Pressure Purge (HPP) condensate systems and provide recommendations for future improvements.

Carnac were engaged by the client to identify, plan and resolve issues with the client's Calciners and to ensure future production is met and achieved sustainably.

Due to an inability to meet duty flow rates for an alumina hydrate conveyor system in an alumina refinery, Carnac was engaged to investigate the drum filters, transfer chutes, conveyors, and conveyor head chutes and develop options for resolving the capacity issues.
