Abstract: According to the actual operation status of the oil and hydrogen refueling station, the typical fire accident scenarios are identified. The calculation models of high- pressure hydrogen leakage jet fire and oil leakage pool fire are established to simulate the typical fire hazard characteristics of ground hydrogen facilities and refueling equipment. The results show that the hazard range is large when the hydrogen jet fire occurs with 45 MPa leakage pressure and 10 mm typical leak aperture, and the damage distance to the equipment and personnel is 21 m and 36 m respectively. The impact distance of serious damage to the equipment is 5~8 m,and the impact distance of thermal radiation injury to personnel is 12~19 m when the refueling gun leakage of 40~60 L/min occurs. The research results can provide reference for layout optimization and safety management of oil and hydrogen refueling station.
