【摘要】 氢气作为炼化企业生产过程中的关键原料，也是主要成本构成要素之一，优化氢气系统对于炼化企业实现节能增效具有重要意义。回顾了氢气系统优化技术的发展历程，特别是氢夹点技术和数学规划法的应用和研究进展。氢夹点技术经历了从单一组分杂质分析到多组分杂质分析的演进，逐步形成了基于图解法的夹点分析方法。数学规划法也逐渐向多组分杂质分析、构建不确定性模型方向发展，应用范围和研究深度不断拓展。结合两种方法的发展趋势，未来研究方向应聚焦于将氢气网络优化与临氢装置的严格流程模拟相结合，集成夹点法与数学规划法形成高效灵活的氢气系统优化技术，以期实现炼化企业氢气系统合理优化。更多还原

【Abstract】 Hydrogen is recognized as both a critical feedstock and a major cost component in petrochemical production. Optimization of hydrogen systems is essential for energy efficiency and cost reduction. The development of hydrogen system optimization technologies is reviewed, with focus on hydrogen pinch technology and mathematical programming methods. Hydrogen pinch technology has evolved from single-component impurity analysis to multi-component analysis, and graphical pinch analysis methods were subsequently established. Mathematical programming approaches are evolving to encompass multi-component impurity analysis and uncertainty modeling frameworks, the application scope and research depth are constantly expanding. Combining the development trends of the two methods, future research should prioritize integrating hydrogen network optimization with rigorous hydrogenation unit simulations and developing hybrid methodologies that combine pinch analysis with mathematical programming, in order to achieve rational optimization of hydrogen systems in refining enterprises.更多还原
