摘　　要：The demand of hydrogen in oil refinery is increasing as market forces and environmental legislation, so hydrogen network management is becoming increasingly important in refineries. Most studies focused on single-objective optimization problem for the hydrogen network, but few account for the multi-objective optimization problem. This paper presents a novel approach for modeling and multi-objective optimization for hydrogen network in refineries. An improved multi-objective optimization model is proposed based on the concept of superstructure. The optimization includes minimization of operating cost and minimization of investment cost of equipment. The proposed methodology for the multi-objective optimization of hydrogen network takes into account flow rate constraints, pressure constraints, purity constraints, impurity constraints, payback period, etc. The method considers all the feasible connections and subjects this to mixed-integer nonlinear programming （MINLP）. A deterministic optimization method is applied to solve this multi-objective optimization problem. Finally, a real case study is intro-duced to illustrate the applicability of the approach.在炼油厂的氢的需求作为市场力量和环境立法正在增加，因此氢网络管理在精炼厂正在变得日益重要。大多数研究集中了于单身者 -- 为氢网络的客观优化问题，而是为多客观的优化问题的很少报道。这份报纸为在精炼厂为氢网络当模特儿和多客观的优化论述一条新奇途径。一个改进多客观的优化模型基于上层建筑的概念被建议。优化包括操作费用的最小化和设备的投资费用的最小化。为氢网络的多客观的优化的建议方法论考虑流动率限制，压力限制，纯净限制，杂质限制，回报时期，等等。方法认为所有可行连接和题目是这到混合整数非线性的编程(MINLP ) 。一个确定的优化方法被使用解决这个多客观的优化问题。最后，真实案例研究被介绍说明途径的适用性。
