摘　　要：对某化工企业的氯化钡项目,收集和量化各工序的物质与能量的输入输出数据,得到制氯化钡生命周期清单(LCI),然后进行生命周期影响评价(LCIA),确定每个工艺流程对于环境的影响。结果表明工业用水量(EIWU)是氯化钡生产全生命周期中最主要的环境影响类型,淡水消耗量(WU)、一次能源消耗(PED)次之。在各个生产工序中,硬煤的消耗对各个指标贡献最大,其次是浓缩母液消耗,氯化钡固体的生成次之。For the barium chloride project of a chemical enterprise,the input and output data of material and energy in each process are collected and quantified to obtain the life cycle inventory(LCI)of barium chloride production,and then the life cycle impact assessment(LCIA)is carried out to determine the impact of each process on the environment.The results show that industrial water consumption(EI-WU)is the most important environmental impact type in the whole life cycle of barium chloride production,followed by fresh water use and primary energy consumption(PED).In each production process,the consumption of hard coal contributes the most to each index,followed by the consumption of concentrated mother liquor,followed by the formation of barium chloride solid.
