摘　　要：【目的】氨是一种高效的储氢介质,在“无碳未来”愿景下,其有望成为未来化石燃料替代品。鉴于氨相对稳定的液态储运形式,利用在役成品油管道构建绿氨-成品油综合运输系统,对绿氨产业链的发展具有重要意义。【方法】介绍了中国绿氨产能分布情况、各运输方式的优劣性及在役成品油管道增输液氨的潜力;从输送介质特性、长输管道系统结构、管材与设备、管输工艺、水力计算方式、运行压力与流速安全共6个方面进行了成品油管道增输液氨系统适应性分析;考虑了绿氨与成品油运输环节的耦合特征,并就“西氨东送”“北氨南运”的供需格局提供了绿氨-成品油综合运输系统规划设想。【结果】随着绿氨产能规模的不断扩大,管道成为首选的长距离运输方式,加之在役成品油管道输送负荷率不足,在经济效益的推动下,成品油管道增输液氨极具潜力;理论层面上,成品油管道与已有液氨长输管道系统相似性高,部分特殊需求可通过工艺或设备改造满足,在制定合理的压力、流速控制策略前提下,在役成品油管道增输液氨的系统适应性整体较强,应进一步采取实验手段验证其可行性。基于此,对绿氨-成品油综合运输系统规划、多种运输方式协同优化、液氨管输运行边界落实及管输批次优化4个方面提出了未来展望。【结论】研究成果可为促进绿氨产业健康发展、提高绿氨-成品油综合运输系统的安全性与经济性提供参考。(图9,表2,参52)[Objective]Ammonia is acknowledged as an efficient hydrogen storage medium,having the potential of being a substitute for fossil fuels in achieving the vision of a“carbon-free future”.Due to its stable liquid-state attributes in storage and transport,establishing a transmission system integrating green ammonia and product oil using in-service product oil pipelines is of important significance for fostering a green ammonia industry chain.[Methods]This paper began with a comprehensive introduction to background information,including the production capacity distribution of green ammonia in China,the pros and cons of different transportation modes,and the potentiality of integrating liquid ammonia transmission into in-service product oil pipelines.Then the adaptability of the system in integrating liquid ammonia transmission was analyzed from six dimensions:properties of transmission mediums,long-distance pipeline structure,pipes and equipment,pipeline transmission technology,hydraulic calculation method,and safety considerations related to operational pressure and flow rates.Considering the coupling characteristics of green ammonia and product oil during transportation,a conceptual plan was outlined for establishing green ammonia and product oil integrated transmission systems based on the supply and demand patterns of“westeast ammonia transmission”and“north-south ammonia transmission”.[Results]As the production capacity of green ammonia continuously expands,pipelines have emerged as the preferred mode for long-distance transportation.Moreover,given the underutilized transmission capacity of existing product oil pipelines,notable potential exists in integrating liquid ammonia transmission into these pipelines to enhance economic benefits.Theoretically,current product oil pipelines bear striking resemblance to existing long-distance liquid ammonia pipeline systems,so they are capable of meeting specific requirements for liquid ammonia transport when offered with technological or equipment upgrades.Therefo
