Why is Hybrid modeling Why is Hybrid modeling more cost effective ?more cost effective ?
No compositional (I/O based) = more flexibilityp ( ) yAll dynamics CAN be capturedRigorous modules available:
Distillation modulesHeat Exchanger, Compressor & OPEN blocksReactor module ( catalytic,treating,cracking etc)Reactor module ( catalytic,treating,cracking etc)Liquid Flow Network / HxNGen (and documentation)Sequential and Simultaneous Matrix Solving schemes integrate seamlesslyseamlesslyApproximations compensated for by the control outputs
Layer Approach minimizes model upkeep costsVP Link allows exactly for desired model fidelityAccuracy: 99% quasi Steady State / 85% full transient
A note about “Fidelity”Fidelity is perceived by Operators ONLY through monitored process variables
Fidelity should reflect the overall accuracy of theSYSTEM= process simulator + “control environment”
