Fire and explosion domino effect caused by overpressure evaluation on pressurized spherical tank

摘要

Pressurized spherical tanks are important facilities in oil & gas transportation andrnstorage, which are the dangerous points due to lots of tanks, huge inventory, a lot ofrnprocess equipment and complex process. Moreover, pressurized spherical tanksrnalways are disposed densely. If one tank has accident, other tanks nearby may bernaffected easily, leading to domino effect. A new calculation method of risk caused byrndomino effect of pressurized spherical tank fire and explosion accidents was providedrnin this paper.
