A targeting algorithm for segregated heat integrated water allocation network

Abstract

The exchange of resources is a critical step toward long-term viability and market economic strength. The use of Process Integration (PI) techniques has resulted in significant savings in resources. Industrial processes rely heavily on water and heat as input variables. Simultaneous conservation of heat and water is regarded as heat-integrated water allocation networks (HIWANs) in the PI. HIWAN problems may be identified for multiple zones. This leads to the specific problem known as segregated targeting problems (STPs), which are prevalent in various industries. Segregated targeting is characterised by the existence of multiple zones and a set of internal sources. The objective of this research is to address the HIWAN problem within the framework of STP to minimize heat and water consumption. The model's applicability is demonstrated by two illustrative examples, in which around a 20 to 65% reduction in resource requirements is reported when compared with the non-zonal integrated model.
