中新网北京8月13日电 近日，中国海洋石油总公司（简称“中国海油”）宣布，全球首套5兆瓦级海上高温烟气余热发电装置在天津顺利完成交付，并将应用于文昌9-7油田的开发项目中。这一创新技术的成功应用，对于实现海上油气田在“双碳”目标下的绿色低碳开发具有里程碑意义。
海上平台通常依赖自产油气燃烧产生的热能来发电，这一过程中会排放大量高温烟气，成为海上油气开发的主要碳排放源。新交付的余热发电装置能够利用这一高温烟气，通过循环流动的有机介质推动膨胀机发电，将废弃的热能转换为清洁电能。
中海油研究总院工程研究设计院机电仪总师安维峥表示，该发电装置的应用预计将提升海上油气田主电站的综合能效7%，从而节省原油和天然气的消耗。据测算，该装置投用后，余热年发电量可达0.4亿千瓦时，满足3万户家庭的年用电需求，运行20年可累计节省天然气消耗约3亿立方米，减少二氧化碳排放约80万吨，相当于植树造林750万棵。
中国海油在海上高温烟气余热发电领域的自主研发和掌握的技术，标志着中国在海上油气田绿色低碳开发方面迈出了重要一步。这一技术不仅适用于中国海上油气平台，还有望推动全球海上油气田在节能减排、降本增效方面的技术进步。

News Title: “Global Invention! China’s CNOOC Delivers First-of-Its-Kind Offshore Thermal Efficiency Power Plant for Waste Heat from High-Temperature Flue Gas”

BEIJING, Aug. 13 (Xinhua) — Recently, China National Offshore Oil Corporation (CNOOC) announced the successful completion and delivery of the world’s first 5-megawatt-class offshore thermal efficiency power plant for waste heat from high-temperature flue gas in Tianjin. This innovative power plant will be applied in the development project of the Wenchang 9-7 oil field. The successful application of this technology marks a milestone in the green and low-carbon development of offshore oil fields under the “double carbon” goal.
Offshore platforms typically rely on the heat generated from the combustion of self-produced oil and gas to produce electricity. This process releases a large amount of high-temperature flue gas, which is a major source of carbon emissions in offshore oil and gas development. The newly delivered power plant can utilize this high-temperature flue gas, converting waste heat into clean electricity through the circulation of an organic working medium that drives an expander.
An Weiqing, Chief Engineer of the Mechanical and Electrical Engineering Division at the Engineering Research Institute of the CNOOC Research Institute, stated that the application of this power plant is expected to enhance the comprehensive energy efficiency of the main power station of offshore oil fields by 7%, thus saving the consumption of crude oil and natural gas. According to calculations, after the plant comes into operation, its annual waste heat electricity generation capacity will reach 40 million kilowatt-hours, sufficient to meet the annual electricity needs of 30,000 households. Over 20 years of operation, the plant is expected to save approximately 300 million cubic meters of natural gas consumption and reduce carbon dioxide emissions by about 8 million tons, equivalent to planting 7.5 million trees.
The autonomous research and development and mastery of technology in the field of offshore thermal efficiency power plant for waste heat from high-temperature flue gas by CNOOC marks an important step forward in China’s green and low-carbon development of offshore oil fields. This technology not only applies to offshore oil platforms in China but also has the potential to promote technological progress in energy conservation, emission reduction, and cost reduction in global offshore oil and gas fields.
