Dust explosion vent sizing is a critical safety calculation used to protect process vessels from internal deflagrations by providing a controlled pressure relief path. This methodology ensures that the maximum pressure developed during an event remains below the structural integrity limits of the equipment. It is particularly relevant for facilities handling combustible crystalline powders like sugar or starch.
