A methodology for the flexibility assessment of side wide heat integration scenarios

Abstract : Energy collaboration in eco-industrial parks between different processes that are nearby aims reducing the use of external energy sources. Many methodologies and approaches have been developed to identify the optimal heat exchanges and transport networks for the energy integration at this scale. Such site wide energy integration reduces the overall costs and further increases energy efficiency beyond what may be achieved by the process scale energy integration. However, integrated processes will become interdependent and the major interactions between these processes constitute a risk for designers, especially in the case of fluctuations in operating conditions. This work presents a mixed integer nonlinear programming (MINLP) model that tests the flexibility of a heat transfer network design between multiple processes subject to multiple scenarios of capacity and operating temperatures and flow rates variation. The model assesses the capability of the heat integration structure to satisfy the heat exchange target and its ability to operate and to cope with varying operating conditions. A virtual case study in the petrochemical industry is used to demonstrate this methodology and its applicability.
