Scope

This document describes a method for the determination of hydrocarbons in petroleum fractions boiling below 315 °C by adsorption with a fluorescent indicator. This document is applicable to the determination of total aromatics, total olefins and total saturated hydrocarbons in petroleum fractions with a boiling point below 315 °C. The measurement range: the volume fraction of aromatics is 5%~99%, and the volume fraction of olefins is 1%~ 55%, and the volume fraction of saturated hydrocarbons is 1% to 95%; this document can also be used for samples with concentrations outside the above range, but the precision is not determined. This document does not apply to samples containing dark components that affect hydrocarbon chromatographic readings. This document is applicable to petroleum products with a full boiling range, but statistical test data show that the precision of this document is not applicable to narrow petroleum fractions with a boiling point close to 315 ℃, such samples cannot be separated normally, and the measurement results are unstable. This document can also be used for spark ignition engine fuels for vehicles (motor gasoline), with or without oxygenated compounds, such as alcohols and ethers (e.g. MTBE, ethanol), and gasoline is the main volume component in the blending components . This document applies to samples containing certain oxygenate blend components. These oxygenated compounds are: methanol, ethanol, methyl tert-butyl ether (MTBE), tert-amyl methyl ether (TAME) and ethyl tert-butyl ether (ETBE), and their concentrations in general blended products will not Affect the determination of hydrocarbons, which flow out together with alcohol eluents and will not be detected, and other oxygen-containing compounds should be verified one by one. When analyzing samples containing oxygenate blending components, the results are corrected based on the whole sample. The applicability of this document to products derived from non-petroleum mineral fuels such as coal, shale or oil sands bitumen has not been determined and the precision may or may not be applicable to such products.
