Hydrogen utility consumption can be reduced further when purification unit is introduced in a hydrogen network. However, targeting and design of the networks involving purification is more difficult than that of the ones involving reuse only. In this paper, when the purification pinch of a hydrogen network involving purification does not change, the target values at a certain purified concentration can be predicted easily and accurately based on the known target values at original purified concentration. The prediction is achieved by using a few relationships developed from the characteristics of hydrogen networks involving purification, and the balances of flow rate and impurity mass load below the purification pinch. The method proposed can simplify the targeting of hydrogen networks with purification unit.
