Abstract: In the hydrogen network, the hydrogen transfer is accompanied by the heat and work transfer. Therefore, these three factors should be considered together. The impact of heat and work on the hydrogen network integration is relatively smaller than that of hydrogen transfer. Based on this, the expansion matrix method for hydrogen network integration considering heat and pressure work is proposed for the first time. In this method, the match of hydrogen has higher priority than the heat and work transfer. The hydrogen network of a refinery is analyzed by the proposed method, and its optimal network is developed.
