炼化尾气发电机组：年省1亿燃气费，天然气消耗锐减70%，炼化厂能源创效核心利器

　　Refining tail gas generator set: saving 100 million yuan in gas costs annually, reducing natural gas consumption by 70%, and becoming a core tool for energy efficiency in refineries

　　炼化厂区生产过程中产生的PSA尾气、合成气、富甲烷气等工业副产尾气，曾是被忽视的能源资源，多数企业依赖天然气作为发电主力燃料，不仅燃料成本居高不下，还造成尾气排空的能源浪费与环保压力。而炼化尾气发电机组的精准投用与优化运营，彻底颠覆了炼化厂传统能源供给模式，成为厂区“少烧天然气、多产清洁电”的核心抓手。某炼化厂动力中心依托炼化尾气发电机组，通过燃料体系重构与机炉联动调控，实现天然气消耗较上年锐减70%，单机组年发电1.79亿千瓦时，年省天然气采购成本超1亿元，让炼化尾气从“工业废汽”变身“创效底气”，为炼化厂能源降本、绿色转型写下生动实践。

　　The industrial by-products such as PSA tail gas, synthesis gas, and methane rich gas generated during the production process in the refining plant area were once overlooked energy resources. Most enterprises rely on natural gas as the main fuel for power generation, which not only results in high fuel costs, but also causes energy waste and environmental pressure due to exhaust emissions. The precise operation and optimization of the refining tail gas generator set have completely overturned the traditional energy supply mode of the refining plant, becoming the core lever for the plant to "burn less natural gas and produce more clean electricity". The power center of a certain refining plant relies on refining tail gas generator sets, and through fuel system reconstruction and machine furnace linkage regulation, achieves a 70% reduction in natural gas consumption compared to the previous year. The annual power generation of a single unit is 179 million kilowatt hours, and the annual provincial natural gas procurement cost exceeds 100 million yuan, transforming refining tail gas from "industrial waste gas" into "efficient bottom gas", and writing vivid practice for energy cost reduction and green transformation of the refining plant.

　　Fuel system reconstruction: Three types of exhaust gas lines enter the furnace, and by-product gas becomes the main source of power generation

　　炼化尾气发电机组的高效创效，核心在于打造适配炼化尾气特性的燃料供给体系，彻底摆脱对天然气的过度依赖。该动力中心针对PSA尾气、合成气、富甲烷气三类炼化副产尾气的组分与热值特点，构建“三类气体、双路输送、优先副产”的专属燃料体系，实现尾气与发电机组的精准匹配：PSA尾气与合成气通过专线稳定输送入炉，富甲烷气与天然气按需汇合调配，形成**“副产气为主、天然气为辅”**的燃烧格局，让炼化尾气成为发电机组的主力燃料。2025年该中心副产气体平均供应量达每小时3万立方米，天然气仅作为应急补充，从源头上大幅削减了优质天然气的消耗，让原本闲置的炼化尾气实现资源化高效利用。

　　The efficient creation of refining tail gas power generation units lies in creating a fuel supply system that is adapted to the characteristics of refining tail gas, completely eliminating excessive dependence on natural gas. The power center has built an exclusive fuel system with "three types of gases, dual transportation, and priority by-products" based on the composition and calorific value characteristics of PSA tail gas, synthesis gas, and rich methane gas, to achieve precise matching between tail gas and generator sets. PSA tail gas and synthesis gas are stably transported into the furnace through a dedicated line, and rich methane gas and natural gas are combined and blended as needed, forming a combustion pattern of "by-product gas as the main fuel, natural gas as the auxiliary", making refined tail gas the main fuel for generator sets. By 2025, the average supply of by-product gas in the center will reach 30000 cubic meters per hour. Natural gas will only be used as an emergency supplement, significantly reducing the consumption of high-quality natural gas from the source and enabling the efficient utilization of idle refining tail gas resources.

　　闭环智能调控：机炉联动精准匹配，每一方尾气物尽其用

　　Closed loop intelligent regulation: precise matching of machine furnace linkage, maximizing the utilization of each exhaust gas source

　　炼化尾气存在组分波动、流量不稳定的特性，若调控不当易造成发电机组燃烧效率低、发电负荷波动等问题，而闭环联动调控机制成为炼化尾气发电机组高效运行的关键保障。该中心建立**“气体流量—燃烧工况—发电负荷”**全链条闭环联动机制，实现尾气供给与机组发电的动态精准匹配：当副产气供应充足时，锅炉与汽机协同提升发电负荷，最大化转化尾气能量；当副产气流量不足时，快速精准降负荷、严控天然气补入量，确保每一方炼化尾气都能转化为有效电能。全年中控室累计发出超3650次负荷调整指令，让发电机组始终处于最优运行状态，3号机组更创下单日发电量突破60万千瓦时的新纪录，实现了尾气能源的“吃干榨净”。

　　The refining tail gas has the characteristics of component fluctuations and unstable flow rate. Improper regulation can easily cause problems such as low combustion efficiency and fluctuating power generation load of the generator set. The closed-loop linkage regulation mechanism has become a key guarantee for the efficient operation of the refining tail gas generator set. The center has established a closed-loop linkage mechanism for the entire chain of "gas flow combustion conditions power generation load" to achieve dynamic and precise matching between exhaust gas supply and unit power generation. When the supply of by-product gas is sufficient, the boiler and turbine work together to increase the power generation load and maximize the conversion of exhaust gas energy; When the by-product gas flow is insufficient, quickly and accurately reduce the load, strictly control the amount of natural gas replenishment, and ensure that every refining tail gas can be converted into effective electrical energy. The central control room has issued over 3650 load adjustment instructions throughout the year, ensuring that the generator units are always in optimal operation. Unit 3 has set a new record of generating over 600000 kilowatt hours of electricity in a single day, achieving a complete depletion of exhaust energy.

　　专业协同与技术革新，进一步释放了炼化尾气发电机组的经济与能源潜力。锅炉与汽机专业打破运营壁垒，建立“实时沟通、快速响应”的一体化运行模式，锅炉实时推送燃烧数据，汽机精准调整发电负荷，让“燃烧—发电”全流程高效衔接。在2025年夏季用电高峰，面对尾气流量波动与外部负荷激增的双重挑战，两大专业连续72小时协同调控，实现天然气零额外消耗，创下节能新纪录。同时，技术团队研发的“气体流量预判—燃烧参数自适应”技术，大幅提升了尾气燃烧效率，设备维护团队全年完成36次关键保养，保障了炼化尾气发电机组的长周期稳定运行，为高效发电筑牢设备根基。

　　Professional collaboration and technological innovation have further unleashed the economic and energy potential of refining tail gas power generation units. The boiler and steam turbine profession breaks down operational barriers and establishes an integrated operation mode of "real-time communication and rapid response". The boiler pushes combustion data in real time, and the steam turbine accurately adjusts the power generation load, enabling efficient connection of the entire "combustion power generation" process. During the peak electricity consumption in the summer of 2025, facing the dual challenges of fluctuating exhaust flow and surging external loads, the two major specialties collaborated for 72 consecutive hours to achieve zero additional consumption of natural gas, setting a new record for energy conservation. At the same time, the "Gas Flow Prediction - Combustion Parameter Adaptive" technology developed by the technical team has significantly improved the efficiency of exhaust combustion. The equipment maintenance team completed 36 key maintenance tasks throughout the year, ensuring the long-term stable operation of the refining exhaust gas generator set and laying a solid foundation for efficient power generation.

　　炼化尾气发电机组的精细化运营，为炼化厂带来了实打实的降本创效成果，更实现了能源利用与绿色环保的双赢。该中心3号炼化尾气发电机组2025年全年发电1.79亿千瓦时，足额覆盖厂区生产用电需求，有效节省大额外购电费；通过最大化利用炼化副产尾气，全年天然气采购成本直接节省超1亿元，燃料成本实现断崖式下降，天然气消耗量较2024年锐减70%，成为炼化厂降本增效的核心增长点。

　　The refined operation of the refining tail gas generator unit has brought tangible cost reduction and efficiency benefits to the refining plant, and has also achieved a win-win situation for energy utilization and green environmental protection. The No. 3 refining tail gas generator unit of the center will generate 179 million kilowatt hours of electricity annually in 2025, fully covering the production electricity demand of the factory area and effectively saving large amounts of purchased electricity bills; By maximizing the utilization of refining by-products such as tail gas, the annual natural gas procurement cost has been directly saved by over 100 million yuan, fuel costs have achieved a cliff like decline, and natural gas consumption has sharply decreased by 70% compared to 2024, becoming a core growth point for refining plants to reduce costs and increase efficiency.

　　更重要的是，炼化尾气发电机组将原本可能排空的工业副产尾气全部资源化利用，既减少了尾气排放带来的环保管控压力，又降低了天然气燃烧带来的碳排放，让炼化厂在能源创效的同时，迈出了绿色低碳转型的坚实步伐。从“依赖天然气”到“尾气为主力”，从“能源消耗”到“资源循环”，炼化尾气发电机组的成功实践证明，炼化厂的工业尾气并非“废汽”，而是蕴藏巨大价值的能源宝库。通过精准的燃料匹配、智能的机炉联动、高效的专业协同，炼化尾气发电机组能持续为炼化厂向“每一千瓦时电量、每一立方米气要效益”赋能，成为炼化厂能源结构优化、降本绿色发展的核心装备。

　　More importantly, the refining tail gas generator unit fully utilizes the industrial by-product tail gas that could have been discharged, reducing both the environmental control pressure caused by tail gas emissions and the carbon emissions caused by natural gas combustion. This enables the refining plant to take solid steps towards green and low-carbon transformation while creating energy efficiency. From "relying on natural gas" to "exhaust gas as the main force", from "energy consumption" to "resource recycling", the successful practice of refining exhaust gas power generation units has proved that the industrial exhaust gas of refineries is not "waste gas", but a treasure trove of energy with enormous value. Through precise fuel matching, intelligent machine furnace linkage, and efficient professional collaboration, the tail gas generator set of the refinery can continuously empower the refinery to achieve "efficiency for every kilowatt hour of electricity and every cubic meter of gas", becoming the core equipment for optimizing the energy structure and reducing costs for green development of the refinery.
