For the process of hydrogen system in the Qilu petrochemical company hd, the hydrogen pinch technology was used to analyze the main problems of hydrogen system and optimize the hydrogen pipe network. On this basis, the hydrogen balance and optimization system, which contains production and consumption balance monitoring, hydrogen production cost accounting, pipe network simulation and scheduling optimization, was constructed. The application shows that the system is achieved the comprehensive control of hydrogen produc- tion, transportation and consumption process. The phenomenon of production and consump- tion imbalance, abnormal emissions in hydrogen system could be discovered timely. The on- line cost calculation of hydrogen production and hydrogen consumption was realized on the basis of process parameters, energy consumption and relevant material prices. At the same time, the soft measurement of the hydrogen flow, velocity and pressure drop in the arbitrary section of the hydrogen pipe network is realized by using the pipe network simulation tech- nology. Based on the above , optimal scheduling scheme with the minimum cost as the ob-jective, combined with the hydrogen pinch theory, the hydrogen supply network was opti- mization. The goal of develop production plans according to hydrogen consumption was achieved, which effectively reduced the operating costs of hydrogen production.
