Heat Integrated Water Regeneration Network Synthesis via Graph-Theoretic Sequential Method

The integration of multiple resources conservation networks is necessary to attain the ever-stringent sustainable goals. This work takes initiatives to develop a heat integrated water network via a proposed P-graph-based sequential methodology. In the first step, a set of feasible water regeneration...
