摘　　要：氢气是一种宝贵而洁净的能量资源,在炼油行业中,它既是石油炼制和石油化工的副产品,又是石油炼制和石油化工加氢工艺过程的重要原料来源。为了满足炼油企业工艺过程对氢气不断变化的需求,实现企业降低成本、节能降耗的目的,必须保证氢气系统在最优的状态下运行。针对这一问题,详细分析了当前炼油厂氢气系统实际调度中的影响因素,建立了综合考虑多项影响因素的氢气系统多周期优化调度的混合整数非线性规划模型,提出了相应的优化调度策略。利用通用建模工具Lingo建模求解,并通过实例证明了模型的有效性和可行性,为实际的炼油厂氢气系统优化调度起到了指导作用。In refinery,hydrogen,which is a precious and clean energy resource,is also the by-product and significant material source of petroleum refining and petrochemical hydrogenation process.To reduce cost and save energy for petrochemical industry,the hydrogen system should be operated under the optimal scheme to meet the varying demand from process.In this paper,the impact factors of hydrogen system operational scheduling are elaborated.A mixed integer nonlinear programming（MINLP）model that involves all the impact factors is established to optimize the multi-period scheduling of hydrogen system and solved with Lingo software.A case study based on the data from certain refinery factory is showed to demonstrate the effectiveness and feasibility of the scheduling methodology,as well as this method proposed plays an important role in guiding the scheduling of hydrogen system in refinery.
