(26f) Reduced-Order Model for a Large-Scale Real-Time Optimization of a Residue Fluidized Catalytic Cracker
The residue fluidized catalytic cracking unit is chosen as a starting point for building the ROM in PYOMO using a trust-region framework for glass box/black box optimization . Since ROMs are sufficiently accurate only in a restricted zone around the point in decision variable space where they are constructed , they are evaluated and compared with the detailed EO model in the following aspects: 1. Ease to generate the model; 2. Model running time; 3. Optimal result accuracy (objective function and variables); 4. Sensitivity to the offset (Îµ); and 5. Stability of extrapolation.
