Abstract: This article introduces the application of oil vapor recovery and treatment facilities added to the oil loading and unloading terminal of a refining company to achieve standard emission of waste gas. The facility adopts low-temperature diesel absorption-alkaline washing desulfurization-desulfurization and total hydrocarbon concentration homogenization-catalytic oxidation technology to treat crude oil, gasoline, naphtha, jet fuel, mixed xylene, ethyl acetate and other oils and chemicals ship loading exhaust gases. The design scale of the low-temperature diesel absorption-alkaline washing desulfurization-desulfurization and total hydrocarbon concentration homogenization unit is 1,500 m³/h, and the design scale of the catalytic oxidation unit is 7,000 m³/h. Through the application research of the low-temperature diesel absorption-alkaline washing-homogenization-catalytic oxidation combination technology, the status and problems in the commissioning and operation of the terminal oil vapor recovery are analyzed, and corresponding optimization measures are proposed. The results show that after the facility is transformed, the mass concentration of non-methane total hydrocarbons in the ship loading exhaust gas can be stably controlled below 50 mg/m³, and the removal rate is higher than 97%, which meets the standard emission requirements of the terminal ship loading exhaust gas after treatment.
