摘要
【目的】在“双碳”目标与相关政策的推动下,甲醇作为氢能载体和绿色燃料,展现出广阔的发展前景。然而,中国甲醇产销地在地理空间上分布不匹配,现有甲醇储运设施整体能力较弱,难以支撑其大规模、长距离、低碳高效输送的需求。与此同时,随着成品油消费量持续下滑,现有成品油储运设施出现较大程度剩余能力。因此,在构建甲醇储存配送网络时,需统筹考虑现有成品油储运设施的整合利用,以实现资源共享与经济效益最大化。【方法】构建了一个甲醇区域多式联运系统规划框架,涵盖供应、运输、需求3个环节,综合考虑公路罐车、铁路罐车、甲醇管道及成品油管道等多种运输方式,建立实际甲醇供需能力(场景1)、2030年甲醇供需能力(场景2)、2030年甲醇供需能力及成品油剩余能力扩大(场景3)共3种甲醇多式联运场景。在此基础上,以甲醇整体运输、甲醇管道建设、成品油管道改造、甲醇储罐建设及成品油储罐改造的总费用最小化为目标函数,添加甲醇物料平衡、甲醇管道建设、成品油管道改造等约束条件,建立适用于多路径、多方式协同优化的甲醇区域多式联运优化模型,以开展甲醇储运设施布局优化分析。【结果】将所建优化模型应用于中国某区域多式联运系统,通过融合成品油管道在内的多种运输方式,可显著降低甲醇储运成本。在场景1中,主干成品油管道Ⅰ、管道Ⅱ、管道Ⅲ均被改造用于甲醇运输,整体负荷率相比仅用于成品油输送时提高了27%~47%。【结论】所提出的规划框架与优化模型可为中国的甲醇区域储运设施规划提供有效的技术路径与决策支持,将成品油管道剩余能力纳入甲醇多式联运系统对促进区域能源协同发展具有重要现实意义。
[Objective]The geographical disparity between methanol production and consumption,compounded by the limited capacity of current storage and transportation facilities,hinders large-scale,long-distance,low-carbon,and efficient methanol transport.Concurrently,the ongoing decrease in refined oil consumption has led to significant overcapacity in existing refined oil storage and transportation facilities.Therefore,when establishing an optimized methanol storage and transportation network,it is essential to comprehensively consider the integration and reutilization of existing refined oil storage and transportation facilities to maximize resource sharing and economic efficiency.[Methods]To address this,a framework for planning a regional methanol multimodal transport system was developed,encompassing supply,transportation,and demand.Multiple transport modes,namely road tankers,rail tankers,methanol pipelines,and refined oil pipelines,were considered comprehensively.Three methanol multimodal-transport scenarios were defined:current methanol supply-demand capacity(Scenario 1),2030 methanol supply-demand capacity(Scenario 2),and 2030 methanol supply-demand capacity with increased refined-oil surplus capacity(Scenario 3).On this basis,an optimization model for the regional multimodal transport of methanol,suitable for the collaborative optimization of multiple routes and modes,was established.The objective function was to minimize the total cost of methanol transportation,construction of methanol pipelines,transformation of refined oil pipelines,construction of methanol storage tanks,and transformation of refined oil storage tanks.Constraints such as methanol material balance,construction of methanol pipelines,and transformation of refined oil pipelines were incorporated to conduct an optimization analysis of the layout of methanol storage and transportation facilities.[Results]The proposed model was applied to a regional multimodal transport system in China,significantly reducing the storage and transportation costs of methanol by integrating multiple modes of transportation including refined oil pipelines.In Scenario 1,the main refined oil pipelines Ⅰ,Ⅰ,and Ⅲ were all repurposed for methanol transport,resulting in an overall load rate increase of 27%-47% compared to their exclusive use for refined oil transport.[Conclusion]The proposed planning framework and optimization model can provide effective technical paths and decision-making support for the planning of regional methanol storage and transportation facilities in China.Incorporating the surplus capacity of refined oil pipelines into the methanol multimodal transport system is of great practical significance for promoting the coordinated development of regional energy.
