资料简介

天然气系统是 美国的温室气体排放，产生 每年大约有1.32亿吨二氧化碳当量(1)。 空气污染物排放标准的显著性也来自于 燃气的上游燃烧生命周期阶段。排放 来自正在出现的LNG生命周期阶段或来自 尚未对SNG的生产进行详细研究。如果更大 美国天然气供应的百分比将来自 这些替代资源，然后是LNG或SNG供应链 排放成为全面理解的重要组成部分 天然气生命周期排放量。此外，比较 只集中于排放的煤和天然气 在公用事业公司可能不够。这样做的目的 研究是对天然气进行生命周期分析（9，10）， LNG和SNG。在处理过程中直接排放空气 将考虑生命周期以及来自 燃料和电的燃烧 过程。与煤炭生命周期的空气排放相比较 为了更好地理解 用煤与自然的优缺点 用于发电的气体。

The natural gas system is one of the largest sources of greenhouse gas emissions in the United States, generating around 132 million tons of CO2 equivalents annually (1). Significant emissions of criteria air pollutants also come from upstream combustion life-cycle stages of the gas. Emissions from the emerging LNG life-cycle stages or from the production of SNG have not been studied in detail. If larger percentages of the U.S. supply of natural gas will come from these alternative sources, then LNG or SNG supply chain emissions become an important part of understanding overall natural gas life-cycle emissions. Also, comparisons between coal and natural gas that concentrate only on the emissions at the utility plant may not be adequate. The objective of this study is to perform a life-cycle analysis (9, 10) of natural gas, LNG, and SNG. Direct air emissions from the processes during the life-cycle will be considered, as well as air emissions from the combustion of fuels and electricity used to run the process. A comparison with coal life-cycle air emissions will be presented, in order to have a better understanding of the advantages and disadvantages of using coal versus natural gas for electricity generation.
