Process Engineering
With arguably one of the most capable process engineering teams in Perth, our team has had extensive experience in industrial mineral process plants both nationally and globally. They have been involved in the extensive computer modelling of alumina refineries within plant simulation softwares SysCAD and FF3, and their thorough knowledge of complex processes has meant that they are able to better identify solutions holistically. For all upgrade works and system reviews, we are sure to engage our process engineers for a high level review of the process and the issue that the client is currently facing. In the past, this has meant quick and detailed problem identification and definition that then can be addressed in detail by the rest of our team.
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.
The refinery-wide extraction steam distribution system was hydraulically modelled to determine network performance under certain operational scenarios to enable better operations practices.
Carnac was engaged to review the original concentrate slurry pipeline designs and optimisation plans and provide recommendations for throughput improvement.
