Application of FLACS in solving the safety problem of densely populated areas near the propane wharf

In view of the actual situation that a a propane wharf is close to the administrative office building, production office building, dormitory and other densely populated areas of adjacent enterprises, FLACS software is applied to carry out three-dimensional physical computational fluid dynamics calculation, and evaluate the influence range of propane gas cloud in typical accident scenarios. After determining the sensitive targets affected by typical accidents, the protective measures of building isolation walls are put forward, and calculated and verified. The results show that the physical wall established by the model can prevent the diffusion of propane gas cloud within the concentration range of explosion interval to the adjacent enterprise personnel dense area, which is an effective safety countermeasures.
