This pair of sink and source are coupled and affected by the reactor operation parameters. It is necessary to consider the variation of these streams caused by these equipments in the integration of the hydrogen network. Based on the analysis on the relation between the coupled sink and source and hydrogen utility consumption of the hydrogen network, the equation is deduced to describe the relation among the Hydrogen Utility Adjustment (HUA), hydrogen consumption of the reactor and coupled sink and source. Based on this, a graphic method is developed to optimize the reactor operation p
