Minimise Output Powder Variation, Maximise Product Quality
Maximise product moisture content – maintaining product quality while reducing specific energy consumption. Maximise use of drying capacity (e.g. respond to ambient air humidity, optimise distribution between the dryer and fluidised beds). Improved energy efficiency. Reduce process variability. Coordinated optimisation of multiple units. Increase product yield or process throughput. Minimise specific energy consumption. Maintain product quality.
Capture Process Data from Existing Automation Systems
Connect to 1000s of different control system. OPC connectivity to all DCS/PLC systems. Integrated data capture and historisation, trending. Custom calculations.
Advanced Process Control, Enables New Levels of Stability Above Traditional Control
Understand process constraints and complex process interactions. A mathematical model of the process input/output dependencies is used to predict the future process output trajectories. Multivariate correlation between variables and actuators, causes and effects. Predict the impact of known disturbances on the operation. Make co-ordinated moves on multiple actuators. Exploit all opportunities to push quality and/or throughput close to the constraint. Multivariable model-predictive dynamic control (MPC). Steady-state economic optimisation by Linear Programme (LP). Inferential virtual sensor modeling by a neural network – to enable continuous product quality measurement by calculating the estimated value.
Proven Optimisation Results for Spray Dryers
10% increase in throughput from the initial “recipe” conditions. 8% reduction in specific energy consumption. Auto-compensation for ambient air humidity changes. Powder moisture in-specification at all times.
Enable Visualisation of predicted vs actual, enable virtual sensors
Continuous improvement by comparing different modeling Scenarios. Compare Actuals vs predicted Data. Enable Virtual Sensors for increased quality awareness and control. Intuitive User configuration experience. Implement a project and get results in 10-12 weeks.
Multi - Unit Coordination and Optimisation
APC’s Linear Programme (LP) Optimiser can span the individual local control functions. Open connectivity to all local PLC control systems. Individual unit models are consolidated into a single multi-unit model. Allows the reconciliation of plant-wide constraints, locates the true global optimum operating point. Maximise throughput. Minimise energy consumption. Downloads real-time operating targets to the control layer.
