to seek measures, such
as in-plant and interplant recovery, for its efficient utilization.
While considering interplant integration, mere water conservation
can incur substantial investment cost due to a large number and distance
of pipelines required as well as pumping costs associated with interplant
flows. The interplant flow, and hence the costs associated with it,
can be reduced by adding some amount of fresh water. The primary objective
of this study is to explore the trade-offs between fresh water consumption
and the interplant flow. A novel method, based on the extensions of
Pinch analysis, is developed to accurately capture the trade-offs
through Pareto optimal solutions. The graphical and algebraic nature
of the developed technique provides efficient solutions with enhanced
visualization. The method is illustrated through examples of water
and hydrogen allocation networks.
