|Abstract: ||Total site integration is considered for energy conservation opportunities across different individual processes. Heat can be integrated through heat exchangers or through non-isothermal mixing of streams. On the other hand, heat can also be integrated across the processes through direct or indirect integration. A methodology is proposed for heat integration across multiple water allocation networks (WANs), where effect of contaminant can be neglected, incorporating the combination of isothermal or non-isothermal mixing as well as direct or indirect integration. The proposed methodology accounts assisted heat transfer between the pinches for improved site-level heat integration. Energy recovery algorithm is applied for energy integration and determination of process grand composite curve (GCC) for each individual process. The method of site-level GCC is extended and modified for targeting the utility requirement in overall plant of WANs. (C) 2011 Curtin University of Technology and John Wiley & Sons, Ltd.|
