%X 二氧化碳捕集利用与封存(CCUS)作为能够实现煤化工行业温室气体大规模减排的前沿技术, 已成为当前研究热点.而管道运输是该技术得以实施的关键环节, 高昂运输成本是影响该技术大规模推广的主要因素.因此, 通过开发煤化工二氧化碳(CO2)捕集压缩、管道运输系统优化模型, 实现CO2管道运输系统内关键环节的工艺和技术优化配置, 降低捕集压缩、运输及注入整个系统的总成本.将模型初步应用于陕西延长榆林煤化工CCUS项目, 结果表明：当封存区域CO2封存需求量小, 而且能够在封存现场提供方便的液化压缩设备时, 榆林能化煤化工企业可以采用气相压缩输送方案, 并结合封存地点液化加压注入；对于大规模CO2封存及运输需求时, 推荐超临界/密相CO2输送, 能够有效减少封存区再次加压环节的成本, 从而使整个流程更为经济</br>Carbon dioxide (CO2) capture, utilization and storage, as an emerging technology that can help reduce coal chemical plant greenhouse gas emission by large scale, have drawn significant attention. Pipeline transportation is an essential part of the technology, but high cost has greatly limited its application. Therefore the main objective is to develop an optimization model for supporting CO2 pipeline transportation system planning to reduce the overall carbon capture utilization and storage (CCUS) system cost by optimizing key technology process of a CO2 transportation system. The developed model was further applied to Shaanxi Yanchang's CCUS project for planning its CO2 transportation system. The results indicated that in case of low demand of CO2 storage, a gas-phase CO2 pipeline transportation system coupled with in-situ compression and injection was recommended. In the case of high demand of CO2 storage, this study would recommend a super-critical / density phase transportation system which could have lower system cost than gas phase pipeline system as the cost for compression at the site of storage can be saved
