In this work we present a framework to generate surrogate models from rigorous process
models embedded in a modelling environment or a process simulator. These unit operations
(ie process flowsheet subsystems) are treated as black-box models to generate data for
fitting and deriving the surrogate. Further, the methodology includes the formulation of a
superstructure optimization problem and solving it to identify the optimal process flowsheet
structure and point of operation from the possible alternatives. The superstructure …
