煉化尾氣發(fā)電機(jī)組：年省1億燃?xì)赓M(fèi)，天然氣消耗銳減70%，煉化廠能源創(chuàng)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(qū)生產(chǎn)過程中產(chǎn)生的PSA尾氣、合成氣、富甲烷氣等工業(yè)副產(chǎn)尾氣，曾是被忽視的能源資源，多數(shù)企業(yè)依賴天然氣作為發(fā)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(fèi)與環(huán)保壓力。而煉化尾氣發(fā)電機(jī)組的精準(zhǔn)投用與優(yōu)化運(yùn)營，徹底顛覆了煉化廠傳統(tǒng)能源供給模式，成為廠區(qū)“少燒天然氣、多產(chǎn)清潔電”的核心抓手。某煉化廠動(dòng)力中心依托煉化尾氣發(fā)電機(jī)組，通過燃料體系重構(gòu)與機(jī)爐聯(lián)動(dòng)調(diào)控，實(shí)現(xiàn)天然氣消耗較上年銳減70%，單機(jī)組年發(fā)電1.79億千瓦時(shí)，年省天然氣采購成本超1億元，讓煉化尾氣從“工業(yè)廢汽”變身“創(chuàng)效底氣”，為煉化廠能源降本、綠色轉(zhuǎn)型寫下生動(dòng)實(shí)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.

　　煉化尾氣發(fā)電機(jī)組的高效創(chuàng)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(duì)天然氣的過度依賴。該動(dòng)力中心針對(duì)PSA尾氣、合成氣、富甲烷氣三類煉化副產(chǎn)尾氣的組分與熱值特點(diǎn)，構(gòu)建“三類氣體、雙路輸送、優(yōu)先副產(chǎn)”的專屬燃料體系，實(shí)現(xiàn)尾氣與發(fā)電機(jī)組的精準(zhǔn)匹配：PSA尾氣與合成氣通過專線穩(wěn)定輸送入爐，富甲烷氣與天然氣按需匯合調(diào)配，形成**“副產(chǎn)氣為主、天然氣為輔”**的燃燒格局，讓煉化尾氣成為發(fā)電機(jī)組的主力燃料。2025年該中心副產(chǎn)氣體平均供應(yīng)量達(dá)每小時(shí)3萬立方米，天然氣僅作為應(yīng)急補(bǔ)充，從源頭上大幅削減了優(yōu)質(zhì)天然氣的消耗，讓原本閑置的煉化尾氣實(shí)現(xiàn)資源化高效利用。

　　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.

　　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(dòng)、流量不穩(wěn)定的特性，若調(diào)控不當(dāng)易造成發(fā)電機(jī)組燃燒效率低、發(fā)電負(fù)荷波動(dòng)等問題，而閉環(huán)聯(lián)動(dòng)調(diào)控機(jī)制成為煉化尾氣發(fā)電機(jī)組高效運(yùn)行的關(guān)鍵保障。該中心建立**“氣體流量—燃燒工況—發(fā)電負(fù)荷”**全鏈條閉環(huán)聯(lián)動(dòng)機(jī)制，實(shí)現(xiàn)尾氣供給與機(jī)組發(fā)電的動(dòng)態(tài)精準(zhǔn)匹配：當(dāng)副產(chǎn)氣供應(yīng)充足時(shí)，鍋爐與汽機(jī)協(xié)同提升發(fā)電負(fù)荷，最大化轉(zhuǎn)化尾氣能量；當(dāng)副產(chǎn)氣流量不足時(shí)，快速精準(zhǔn)降負(fù)荷、嚴(yán)控天然氣補(bǔ)入量，確保每一方煉化尾氣都能轉(zhuǎn)化為有效電能。全年中控室累計(jì)發(fā)出超3650次負(fù)荷調(diào)整指令，讓發(fā)電機(jī)組始終處于最優(yōu)運(yùn)行狀態(tài)，3號(hào)機(jī)組更創(chuàng)下單日發(fā)電量突破60萬千瓦時(shí)的新紀(jì)錄，實(shí)現(xiàn)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(yè)協(xié)同與技術(shù)革新，進(jìn)一步釋放了煉化尾氣發(fā)電機(jī)組的經(jīng)濟(jì)與能源潛力。鍋爐與汽機(jī)專業(yè)打破運(yùn)營壁壘，建立“實(shí)時(shí)溝通、快速響應(yīng)”的一體化運(yùn)行模式，鍋爐實(shí)時(shí)推送燃燒數(shù)據(jù)，汽機(jī)精準(zhǔn)調(diào)整發(fā)電負(fù)荷，讓“燃燒—發(fā)電”全流程高效銜接。在2025年夏季用電高峰，面對(duì)尾氣流量波動(dòng)與外部負(fù)荷激增的雙重挑戰(zhàn)，兩大專業(yè)連續(xù)72小時(shí)協(xié)同調(diào)控，實(shí)現(xiàn)天然氣零額外消耗，創(chuàng)下節(jié)能新紀(jì)錄。同時(shí)，技術(shù)團(tuán)隊(duì)研發(fā)的“氣體流量預(yù)判—燃燒參數(shù)自適應(yīng)”技術(shù)，大幅提升了尾氣燃燒效率，設(shè)備維護(hù)團(tuán)隊(duì)全年完成36次關(guān)鍵保養(yǎng)，保障了煉化尾氣發(fā)電機(jī)組的長周期穩(wěn)定運(yùn)行，為高效發(fā)電筑牢設(shè)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(fā)電機(jī)組的精細(xì)化運(yùn)營，為煉化廠帶來了實(shí)打?qū)嵉慕当緞?chuàng)效成果，更實(shí)現(xiàn)了能源利用與綠色環(huán)保的雙贏。該中心3號(hào)煉化尾氣發(fā)電機(jī)組2025年全年發(fā)電1.79億千瓦時(shí)，足額覆蓋廠區(qū)生產(chǎn)用電需求，有效節(jié)省大額外購電費(fèi)；通過最大化利用煉化副產(chǎn)尾氣，全年天然氣采購成本直接節(jié)省超1億元，燃料成本實(shí)現(xiàn)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(diǎn)。

　　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(fā)電機(jī)組將原本可能排空的工業(yè)副產(chǎn)尾氣全部資源化利用，既減少了尾氣排放帶來的環(huán)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(chuàng)效的同時(shí)，邁出了綠色低碳轉(zhuǎn)型的堅(jiān)實(shí)步伐。從“依賴天然氣”到“尾氣為主力”，從“能源消耗”到“資源循環(huán)”，煉化尾氣發(fā)電機(jī)組的成功實(shí)踐證明，煉化廠的工業(yè)尾氣并非“廢汽”，而是蘊(yùn)藏巨大價(jià)值的能源寶庫。通過精準(zhǔn)的燃料匹配、智能的機(jī)爐聯(lián)動(dòng)、高效的專業(yè)協(xié)同，煉化尾氣發(fā)電機(jī)組能持續(xù)為煉化廠向“每一千瓦時(shí)電量、每一立方米氣要效益”賦能，成為煉化廠能源結(jié)構(gòu)優(yōu)化、降本綠色發(fā)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.
