Paper description    For refineries, the minimization of fresh hydrogen consumption is significant to minimize operation cost and maximize profit. To get such effect, in addition to the flow rate and purity of hydrogen sources and sinks, the main constraints are pressure and impurities based on the operation requirements. Based on the existing hydrogen network, by introducing pressure cascade use and impurity diverted path corresponding to pressure and impurity constraints, this paper presents an experiential method for hydrogen network optimization. As complement to integration methodology, the reduction of fresh hydrogen is reliable and attainable. Finally, a refinery case study is used to illustrate the method.
