摘要
我国的CO_2排放量已居世界首位,碳减排压力巨大。为了控制温室气体的排放,CO_2捕捉与封存技术呈现出快速发展的趋势,CO_2管道输送相关的工艺技术也备受关注。基于纯CO_2物性以及管输CO_2中杂质的种类与含量,分析了管输CO_2中的杂质会对其混合物性产生的影响规律;从管输相态选择、总体管输工艺、管输CO_2杂质预处理、设计压力和流动安全保障等方面,探讨了国内外CO_2管道输送工艺技术的发展,并对我国CO_2管道输送研究提出了相应的建议。
At present, the carbon dioxide emissions in China have been ranked first in the world, which leads to enor mous pressure on carbon emissions. In order to control the emission of greenhouse gases, CO2 capture and geological storage technology has been developed rapidly, so also largely concern on CO2 pipeline transportation technology. Based on the pure CO2 property and the impurity, deeply analyz the effect of CO2 impurity on the property of the mixture CO2 in the pipeline. Then, introduce the current situation of CO2 pipeline transportation technology development worldwide in such aspect as phase selection, overall transportation system, impurity pretreatment, design pressure and flow assurance. Besides, analyze the problems and relative advices in CO2 pipeline transportation technology research in China.
