【摘要】：二氧化碳捕集利用與封存(CCUS)作為能夠?qū)崿F(xiàn)煤化工行業(yè)溫室氣體大規(guī)模減排的前沿技術(shù),已成為當(dāng)前研究熱點.而管道運輸是該技術(shù)得以實施的關(guān)鍵環(huán)節(jié),高昂運輸成本是影響該技術(shù)大規(guī)模推廣的主要因素.因此,通過開發(fā)煤化工二氧化碳(CO_2)捕集壓縮、管道運輸系統(tǒng)優(yōu)化模型,實現(xiàn)CO_2管道運輸系統(tǒng)內(nèi)關(guān)鍵環(huán)節(jié)的工藝和技術(shù)優(yōu)化配置,降低捕集壓縮、運輸及注入整個系統(tǒng)的總成本.將模型初步應(yīng)用于陜西延長榆林煤化工CCUS項目,結(jié)果表明:當(dāng)封存區(qū)域CO_2封存需求量小,而且能夠在封存現(xiàn)場提供方便的液化壓縮設(shè)備時,榆林能化煤化工企業(yè)可以采用氣相壓縮輸送方案,并結(jié)合封存地點液化加壓注入;對于大規(guī)模CO_2封存及運輸需求時,推薦超臨界/密相CO_2輸送,能夠有效減少封存區(qū)再次加壓環(huán)節(jié)的成本,從而使整個流程更為經(jīng)濟.
[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.
