Abstract: This study discusses the treatment technologies and principles for volatile organic compounds (VOCS) and benzene homologues emitted during the loading of gasoline, naphtha and jet fuel at a petrochemical terminal. The operational effectiveness of a combined "low-temperature catalytic oxidation" process in treating VOCS and benzene series from dock loading operations is presented. Results demonstrate that hydrocarbons, benzene homologues and other VOCS achieve compliant emissions after treatment through this process. By implementing sealing modification to vessel vapor recovery systems and upgrading inerting system maintenance to reduce oxygen content in loading vapors, the safe operation of ship-to-shore docking systems during loading operations can be ensured. This study provides a reference for VOCS emission control in terminal loading operations.
