Advisian has a well-developed set of tools and libraries to enhance and streamline process simulation of alumina refineries.
These tools, plus a ‘critical mass’ of process simulation workload, enable us to provide value to the clients in a robust and cost-effective manner.
These tools and libraries include capabilities for:
-
Greenfield refinery design and optimisation, with linkages to capital cost and OPEX modules for NPV optimisation
-
Operating refinery as-built modelling and calibration
-
Water balance
-
Sankey diagrams
-
Rapid evaluation of impact of proposed modifications on overall refinery balance
-
Develop sensitivities matrix to enable day-to-day monitoring of financial impact of process deviations
-
Brownfield expansion design and optimisation
-
Monte Carlo simulation for risk analysis and risk management
-
Bauxite composition and reaction chemistry
-
Impurity balance chemistry and reaction kinetics
The combined effect of the above is the ability to adopt numerous variations of the process flowsheet model in a much faster, representative and reproducible manner.
We offer process simulation services on a per-task basis or as an ongoing service. In the latter case, we provide a full management service, including model documentation, change control, software updates, annual recalibration and annual production planning. The client retains full access to the model files.
