The Hydrogen Network Optimization of a Complex Refinery

In this paper, the hydrogen distribution network of a complex refinery is optimized by the hydrogen surplus pinch method. By plotting the hydrogen purity profiles and hydrogen surplus diagrams, the hydrogen pinch with hydrogen purity of 87% is identified. The corresponding minimum hydrogen utility consumption is 17730.5 Nm3/h. Moreover, the optimal hydrogen distribution network with minimum utility consumption is designed. Compared with the current hydrogen network, the hydrogen utility consumption can be reduced by 10.45%.
