中新社山东东营10月16日电 (周艺伟)中国首个百万吨级低浓度CCUS(二氧化碳捕集利用与封存)全链条示范工程,16日在位于山东东营的中国石化胜利油田开工建设。

“齐鲁石化—胜利油田百万吨级CCUS项目”是中国首个百万吨级CCUS项目,主要捕集煤制氢装置排放的高浓度尾气,二氧化碳含量在90%左右。自2022年8月投产以来,该项目已累计封存二氧化碳14亿标准立方米,提升原油采收率超15个百分点。目前,齐鲁石化—胜利油田百万吨级CCUS示范区日产油由220吨上升到525吨,还同步配套建设了中国首条百公里级二氧化碳长输管道,形成了完整的碳减排产业链。

在高浓度气源捕集实现工业化突破后,胜利油田将攻关方向转向更难捕集、排放规模更大的低浓度燃煤烟气。这类烟气的二氧化碳浓度仅为12%至15%,还含有硫、氮氧化物等杂质,捕集难度显著增大。

经过攻关,胜利油田采用自主研发的新型吸收剂和节能再生工艺,实现捕集率超过90%、产品纯度达99.5%以上,且每吨二氧化碳捕集热耗降至2.0吉焦以下,达到国际领先水平,为低浓度CCUS工程建设奠定坚实基础。

本次开工的百万吨级低浓度CCUS示范工程预计2028年底建成投运,所捕集的二氧化碳将通过70余口注气井注入滩坝砂、浊积岩和页岩油等不同类型的油藏。工程同步配套“风电+储能+直连线路+CCUS捕集”源网荷储一体化系统,规划13台风机、总装机98.8兆瓦,年发绿电2.17亿度,直供碳捕集装置,实现“绿电直连、低碳捕集”的闭环模式,这一模式在中国尚属首创。
