Comparison of H₂, LNG, and LPG explosion characteristics in a limited space using CFD Simulation

Abstract

-The demand for hydrogen is steadily increasing every year, and the facilities to produce and transfer hydrogen are being increased as well. Therefore, the possibility of a critical accident at hydrogen is expected to increase. Furthermore, the materials most likely to cause accidents at industrial sites are LPG 61%, hydrogen 12%, and LNG 10%, and the frequency of accidents due to these three combustible gases is relatively high. Thus, a CFD simulation was used to compute the explosion risk of danger-frequent combustible gaseshydrogen, LNG, and LPG -within a limited space, and the outcomes were compared and analyzed to review the risk of explosion of each gase within a limited space.
