【摘要】: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(CO_2)捕集压缩、管道运输系统优化模型,实现CO_2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CO_2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CO_2封存及运输需求时,推荐超临界/密相CO_2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.
[Abstract]:The use of carbon capture and storage (CCUS) as the cutting-edge technology of coal chemical industry to achieve large-scale greenhouse gas emission reduction, has become the focus of current research. The pipeline transportation is the key technology to implement the high transport costs are the main factors that influence the technology of large-scale promotion. Therefore, through the development of coal chemical carbon dioxide (CO_2) capture compression, optimization model of pipeline transportation system, implementation process and technology optimization of key CO_2 pipeline transportation system, reduce capture compression, transport and total cost into the whole system. The model is applied in Shaanxi to extend the Yulin coal chemical project CCUS, the results show that when the CO_2 storage demand for small storage zone, but also to provide a convenient site on the storage of liquefied compressed equipment, Yulin coal chemical enterprises can be compressed and combined with the gas transportation, storage. Point liquefaction pressure injection; for large-scale CO_2 storage and transportation needs, we recommend Supercritical / dense phase CO_2 transport, which can effectively reduce the cost of re pressurized links in the storage area, and make the whole process more economical.
