• Designing pressure relief devices for three‐phase systems consisting of solids, liquids and vapors requires an in‐depth knowledge of the fluid dynamics and of the thermodynamic effects in the reactor. The behavior of foaming three‐phase systems is, to date, still not well understood. In this research, these systems are systematically studied, taking the solid properties into account. Also, the applicability of two‐phase pressure relief models to three‐phase systems is investigated with the help of the simulation tool SAFIRE/Vent. The results obtained contribute significantly to the better design of pressure relief devices and to more accurate predictions of the three‐phase venting behavior and the solid discharge. As part of a safety concept, reactors and other high pressure containers have to be protected against excessive pressure by pressure relief devices such as bursting discs or safety relief valves. The influence of certain solid properties on foaming three‐phase pressure relief is investigated. This research finally leads to design criteria for an emergency relief system of reactive multiphase mixtures under various boundary conditions.
