标准摘要
[中文适用范围]： 本标准提供基于多组分烃类混合物（如原油和汽油）总排放量估算结果的方法，用于推算单个烃类物种的排放量。总排放量可依据API MPMS第19.1章（固定顶储罐）、第19.2章（浮顶储罐）、第19.5章（船舶）等多种方法估算。该过程称为“物种分化”。烃类混合物排放的物种分化考虑了高挥发性组分蒸发速率较快的事实，导致气相中的混合物组成与液相中的组成存在差异。本标准所呈现的方法假设存在足够的液体，使得液体表面的化学成分不会因蒸发损失而发生改变。此外，本标准还包含用于依据API MPMS第19.1章和第19.2章估算排放的参考信息，以及API其他相关内容。 [外文原描述]： Provides methodology to estimate emissions of individual hydrocarbon species using the total emissions of multicomponent hydrocarbon mixtures (such as crude oils and gasoline) estimated from API MPMS Ch. 19.1 for fixed-roof tanks, API MPMS Ch. 19.2 for floating-roof tanks, API MPMS Ch. 19.5 for marine vessels, and many other methods used for total hydrocarbon emission estimates. This process is referred to as speciation. Speciation of emissions from hydrocarbon mixtures accounts for the higher evaporation rate of the more volatile components, resulting in a different composition of the mixture in the vapor phase than in the liquid phase. The methodology presented in this standard assumes that there is sufficient liquid present such that the chemical composition at the liquid surface may be considered to not change as a result of the evaporative loss. This standard also contains reference information used for estimating emissions in accordance with API MPMS Ch. 19.1 and 19.2, and API
