- 摘要:
- 在“双碳”战略与炼化行业转型升级的双重背景下，蒸汽系统作为炼化企业的核心公用工程单元，其运行效率直接影响企业能耗成本与碳排放水平。针对传统碎片化节能模式的局限性，基于过程系统能量集成理论，提出系统化运行管理的蒸汽节能理论框架，构建涵盖“源—网—荷—储”全环节的协同优化体系。通过对某石化公司近年来蒸汽优化实践的系统梳理，从锅炉运行模式优化、管网压力精准控制、用户端精细化管控、应急柔性建设 4 个维度展开分析，论证了系统化管理对节能效益的放大效应。研究表明，强化系统化运行管理可使蒸汽节能从局部优化走向全局最优，实现安全与节能的统筹兼顾，为炼化企业绿色低碳转型提供可复制的管理范式。
Under the dual background of the "dual carbon" strategy and the transformation and upgrading of the refining and
chemical industry, the steam system, as a core utility unit of refining and chemical enterprises, directly affects the enterprise's
energy consumption cost and carbon emission level through its operational efficiency. Addressing the limitations of the traditional
fragmented energy -saving model, this paper proposes a theoretical framework for steam energy saving based on systematic
operation management, grounded in process system energy integration theory. A collaborative optimization system covering the
entire chain of "source-network-load-storage" is constructed. Through a systematic review of the steam optimization practices of
Daqing Petrochemical Company in recent years, this paper analyzes four key technical dimensions: boiler operation mode
optimization, precise pipeline pressure control, refined user -side management, and emergency flexibility construction. The
amplification effect of systematic management on energy -saving benefits is demonstrated. Research shows that strengthening
systematic operation management can shift steam energy saving from local optimization to global optimum, achieving the
coordination of safety and energy conservation, and providing a replicable management paradigm for the green and low-carbon
transformation of refining and chemical enterprises.
