摘　　要：页岩油的提炼是一项复杂而高能耗的过程,为评估生产对环境的影响,需进行生命周期评价(life cycle assessment,LCA)和碳足迹分析。文章通过建立抚顺式干馏工艺的生命周期评价模型,量化分析了页岩油生产周期中各单元过程的环境指标累积贡献。研究结果显示:干馏单元的全球变暖潜值(GWP)、一次能源消耗(PED)、水资源消耗(WU)和酸化潜值(AP)分别达6330 kg CO_(2)eq、156200 MJ、14653 kg和410 kg SO_(2)eq;破碎筛选与开采单元的GWP、PED和WU分别为2478.65 kg CO_(2)eq、34540 MJ和6780 kg。数据质量评估表明所有指标不确定度均低于17%。碳足迹分析表明,每生产1 t页岩油将排放8910 kg CO_(2),其中干馏(33.68%)、破碎筛选(27.63%)和瓦斯开采(26.51%)为主要排放源。研究结果为页岩油生产的环境优化提供了理论依据。The extraction of shale oil is a complex and energy-intensive process that requires Life Cycle Assessment(LCA)and carbon footprint analysis to assess the environmental impact of production.In this paper,a life cycle evaluation model of Fushun retorting process was established to quantitatively analyze the cumulative contribution of environmental indicators of each unit process in the production cycle of shale oil.The results show that the global warming potential(GWP),primary energy consumption(PED),water resource consumption(WU)and acidification potential(AP)of the redistillation unit are 6330 kg CO_(2) eq,156200 MJ,14653 kg and 410 kg SO_(2) eq,respectively.The GWP,PED and WU of the crushing,screening and mining unit were 2478.65 kg CO_(2) eq,34540 MJ and 6780 kg,respectively.The data quality evaluation showed that the uncertainty of all indicators was less than 17%.Carbon footprint analysis shows that every 1 t of shale oil production will emit 8910 kg CO_(2),of which dry distillation(33.68%),crushing and screening(27.63%)and gas extraction(26.51%)are the main emission sources.The research results provide a theoretical basis for environmental optimization of shale oil production.
