摘要 文章运用生命周期评价方法,对我国东南某大型石化集团聚氯乙烯生产过程的资源消耗及环境影响进行量化与估算。结果表明:生产1t聚氯乙烯的总能量消耗为6102.24MJ,环境影响负荷为0.49标准人当量。聚氯乙烯生产的主要环境影响为大气颗粒物污染、光化学臭氧合成、酸化和全球变暖。 Life cycle assessment(LCA)was used to estimate the resource consumption and environmental impact in polyvinyl chloride (PVC)production of a large SINOPEC Group in the southeast of China. Results showed that for 1t PVC production,total energy consumption was 6,102.24MJ,and environmental impact load was 0.49eq.(/p.a). In which polymerization process of vinyl chloride monomer for PVC was the largest energy consumption,accounting for 82.7%. Gas pollutants was mainly from energy production,while PVC process was main source of water pollutants and solid waste. Air particulate,photochemical synthesis and ozone,acidification and global warming were major environmental influences in PVC production. Environmental impact region in PVC production was shown as global,regional and local.
