尽管目前对汽油组分影响各种环境条件的理解还很有限 ,但已经认识到 ,现有燃料中的几种组分若以高浓度释放到大气中 ,对环境是有害的 ,如溢漏、挥发损耗或不完全燃烧。这些组分包括芳烃特别是苯、高蒸汽压烃如n -丁烷、反应性烃如烯烃以及硫化合物 ,它们会促使烟和酸的形成。本文将阐述与当前炼油加工过程有关的这些环境影响问题。
Although the current understanding of the various gasoline components affecting environmental conditions is still limited, it has been recognized that several components of existing fuels that are released into the atmosphere at high concentrations are environmentally harmful, such as spills, Volatile or incomplete combustion. These components include aromatic hydrocarbons, especially benzene, high vapor pressure hydrocarbons such as n-butane, reactive hydrocarbons such as olefins and sulfur compounds, which promote the formation of smoke and acid. This article describes these environmental impacts associated with the current refining process.
