Thermal radiation calculation for LNG storage tank areas

The “Code for Fire Protection Design of Oil and Gas Engineering Projects” (GB50183-2015) specifies the upper limit for the heat radiation intensity that station facilities are allowed to withstand. Specific heat radiation calculations require consideration of the heat radiation generated in cases such as leaks or fires in LNG storage tanks; the intensity of this heat radiation is usually estimated using formulas or models. Thermal radiation calculations take into account factors such as the size, shape, and temperature of the flame, as well as the distance between the target being heated and the fire source. Special software such as PHAST and FLACS may be used for simulation and calculation in actual computations. These software programs can simulate the flame characteristics and thermal radiation distribution under various leakage conditions, thereby predicting the intensity of thermal radiation that the facilities within a station may be exposed to in the event of an accident. Regarding the requirements specified in the regulations, it is necessary to follow the standard requirements and take into account the actual conditions of the project. By using mathematical formulas or models, it is possible to determine whether the intensity of thermal radiation that the facilities within the station may experience in the event of potential leaks or fires exceeds the allowable values specified by the standards. If it is exceeded, corresponding safety measures need to be taken. .
