Research on VOCs Composition Emissions in the Oil Transport Link Based on Multi-source Detection Data

Volatile Organic Compounds (VOCs) generated in the oil transportation process are important precursors for secondary organic aerosols (SOA) and photochemical smog. These emissions have become one of the key environmental constraints in China’s 14th Five-Year Plan. Due to the diversity of oil products, VOC composition varies significantly among different types of oil, such as crude oil and refined oil, making it a critical consideration in the development of pollution control policies and treatment processes for the transportation sector. This study employs gas chromatography with a hydrogen flame ionization detector and mass spectrometry to analyze VOCs emitted from 31 types of crude oil and refined oil samples under simulated transportation and storage conditions. By utilizing multi-source detection and mass spectrometry overlay, along with area normalization spectral analysis, we provide a more accurate breakdown of VOC components from crude oil, asphalt mixtures, gasoline, diesel, aviation kerosene, and naphtha. Special attention is given to the olefin and aromatic hydrocarbon components, which contribute significantly to ozone formation. The research results can provide important basis for the research and design selection of VOCs treatment technology and equipment in the transportation process.
