Abstract
In order to provide a theoretical basis for the overall layout of LNG terminal and offshore elevated flares,a suitable mathematical model is built to analyze the interaction between the evaporation&diffusion of LNG in the terminal sump and thermal radiation by the flares.A large amount of numerical calculation results show that the concentration of combustible vapor at the flare tip is inversely proportional to the distance from the flare to the terminal sump,is proportional to the area of the sump opening,and has little relationship with wind velocity.The heat radiation acting on the wharf is proportional to the flare capacity,and is inversely proportional to the flare height as well as the distance from the wharf to the flare.In order to control the concentration of combustible vapor at the flare tip,the distance between the flare and the sump should be within the range of 88～115 m.In order to control the intensity of thermal radiation,the distance between the wharf's fire control room and the flare should be within the range of 25～104 m.The distance between the wharf's working platform and the flare should be within the range of 74～140 m,and the distance between the pipe gallery of approach bridge and the flare should be within the range of 5～140 m.关键词
