Abstract: Pinch analysis was conducted to reach the minimal hydrogen utility in a hydrogen distribution network in refinery，in which the constraints of hydrogen flow rate，hydrogen purity，contaminants and stream pressure were taken into consideration. Some matching rules were proposed in the optimization of a hydrogen distribution network. A case study was used to perform the analysis and calculation. The pinch analysis is an effective method in the optimization of hydrogen distribution network. The matching rules proposed in this paper can be useful in optimizing hydrogen distribution network.
