Personal risk calculation of domino accident in LNG storage tank area
In order to calculate the personal risk of domino accident in LNG storage tank area more accurately, this paper puts forward the calculation method of personal risk of domino accident in LNG storage tank area. Firstly, the overpressure at different distances of LNG storage tank steam cloud explosion accident is analyzed, and the domino upgrade probability of storage tanks at different positions is calculated based on probit model.According to the accident transmission direction, Bayesian network is used to deduce the accident probability of each tank, and finally, personal risk is calculated according to the accident consequences. The results show that the explosion overpressure of LNG storage tank decreases with the increase of distance, and the decrease is more severe at close distance The accident escalation probability of pressurized vessels gradually increases with the increase of overpressure, and the main increasing interval is 3.0×104-9.0×104.The secondary domino accident unit is easily affected by multiple accidents, and the accident probability can be calculated more accurately by Bayesian network When Domino accident is considered, the calculation result of personal risk increases obviously compared with that without consideration
