煉化尾氣發電機組：年省1億燃氣費，天然氣消耗銳減70%，煉化廠能源創效核心利器

　　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

　　煉化廠區生產過程中產生的PSA尾氣、合成氣、富甲烷氣等工業副產尾氣，曾是被忽視的能源資源，多數企業依賴天然氣作為發電主力燃料，不僅燃料成本居高不下，還造成尾氣排空的能源浪費與環保壓力。而煉化尾氣發電機組的精準投用與優化運營，徹底顛覆了煉化廠傳統能源供給模式，成為廠區“少燒天然氣、多產清潔電”的核心抓手。某煉化廠動力中心依托煉化尾氣發電機組，通過燃料體系重構與機爐聯動調控，實現天然氣消耗較上年銳減70%，單機組年發電1.79億千瓦時，年省天然氣采購成本超1億元，讓煉化尾氣從“工業廢汽”變身“創效底氣”，為煉化廠能源降本、綠色轉型寫下生動實踐。

　　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.

　　燃料體系重構：三類尾氣專線入爐，副產氣成發電主力

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

　　煉化尾氣發電機組的創效，核心在于打造適配煉化尾氣特性的燃料供給體系，徹底擺脫對天然氣的過度依賴。該動力中心針對PSA尾氣、合成氣、富甲烷氣三類煉化副產尾氣的組分與熱值特點，構建“三類氣體、雙路輸送、優先副產”的專屬燃料體系，實現尾氣與發電機組的精準匹配：PSA尾氣與合成氣通過專線穩定輸送入爐，富甲烷氣與天然氣按需匯合調配，形成**“副產氣為主、天然氣為輔”**的燃燒格局，讓煉化尾氣成為發電機組的主力燃料。2025年該中心副產氣體平均供應量達每小時3萬立方米，天然氣僅作為應急補充，從源頭上大幅削減了優質天然氣的消耗，讓原本閑置的煉化尾氣實現資源化利用。

　　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.

　　閉環智能調控：機爐聯動精準匹配，每一方尾氣物盡其用

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

　　煉化尾氣存在組分波動、流量不穩定的特性，若調控不當易造成發電機組燃燒效率低、發電負荷波動等問題，而閉環聯動調控機制成為煉化尾氣發電機組運行的關鍵保障。該中心建立**“氣體流量—燃燒工況—發電負荷”**全鏈條閉環聯動機制，實現尾氣供給與機組發電的動態精準匹配：當副產氣供應充足時，鍋爐與汽機協同提升發電負荷，最大化轉化尾氣能量；當副產氣流量不足時，快速精準降負荷、嚴控天然氣補入量，確保每一方煉化尾氣都能轉化為有效電能。全年中控室累計發出超3650次負荷調整指令，讓發電機組始終處于運行狀態，3號機組更創下單日發電量突破60萬千瓦時的新紀錄，實現了尾氣能源的“吃干榨凈”。

　　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.

　　專業協同與技術革新，進一步釋放了煉化尾氣發電機組的經濟與能源潛力。鍋爐與汽機專業打破運營壁壘，建立“實時溝通、快速響應”的一體化運行模式，鍋爐實時推送燃燒數據，汽機精準調整發電負荷，讓“燃燒—發電”全流程銜接。在2025年夏季用電高峰，面對尾氣流量波動與外部負荷激增的雙重挑戰，兩大專業連續72小時協同調控，實現天然氣零額外消耗，創下節能新紀錄。同時，技術團隊研發的“氣體流量預判—燃燒參數自適應”技術，大幅提升了尾氣燃燒效率，設備維護團隊全年完成36次關鍵保養，保障了煉化尾氣發電機組的長周期穩定運行，為發電筑牢設備根基。

　　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.

　　煉化尾氣發電機組的精細化運營，為煉化廠帶來了實打實的降本創效成果，更實現了能源利用與綠色環保的雙贏。該中心3號煉化尾氣發電機組2025年全年發電1.79億千瓦時，足額覆蓋廠區生產用電需求，有效節省大額外購電費；通過最大化利用煉化副產尾氣，全年天然氣采購成本直接節省超1億元，燃料成本實現斷崖式下降，天然氣消耗量較2024年銳減70%，成為煉化廠降本增效的核心增長點。

　　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，煉化尾氣發電機組將原本可能排空的工業副產尾氣全部資源化利用，既減少了尾氣排放帶來的環保管控壓力，又降低了天然氣燃燒帶來的碳排放，讓煉化廠在能源創效的同時，邁出了綠色低碳轉型的堅實步伐。從“依賴天然氣”到“尾氣為主力”，從“能源消耗”到“資源循環”，煉化尾氣發電機組的成功實踐證明，煉化廠的工業尾氣并非“廢汽”，而是蘊藏巨大價值的能源寶庫。通過精準的燃料匹配、智能的機爐聯動、的專業協同，煉化尾氣發電機組能持續為煉化廠向“每一千瓦時電量、每一立方米氣要效益”賦能，成為煉化廠能源結構優化、降本綠色發展的核心裝備。

　　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.
