SYSTEMS, PROGRAM PRODUCT, AND METHODS FOR SYNTHESIZING HEAT EXCHANGER NETWORKS THAT ACCOUNT FOR FUTURE HIGHER LEVELS OF DISTURBANCES AND UNCERTAINTY, AND IDENTIFYING OPTIMAL TOPOLOGY FOR FUTURE RETROFIT

A system, methods, and user-friendly program product to optimize energy recovery for a process or cluster of processes under all possible combinations of given process changes and stream-specific minimum temperature approach values without enumeration, are provided. The systems, methods, and program product can include steps/operations to identify a set of common-structure heat exchanger network designs which allow for construction of a physically exchanger network easily retrofittable to accommodate time-dependent new operating modes, disturbances, and uncertainty schemes.
