Advanced HENs Design for Multi-Period Operation Using P-graph

This work deals with multi period-operation HEN synthesis and explores the use of the Process Graph (P-graph) with its associated algorithms for the problem. Heat exchanger networks (HEN) synthesis has been evolving from a steady state towards design flexibility and resilience. it designs a network for a set of. steady states, assigned to operation periods - multiperiod operation. The P-graph enables the systematic automated generation of rigorous superstructures and the derivation of the optimal solution HENS via the combinatorially Accelerated Branch and Bound optimisation algorithm (ABB).
