Modeling pressure relief devices mounted on a common inlet manifold.

Large equipment items, such as distillation column systems, compressors, or major pressure vessels, are commonly protected by multiple pressure relief devices mounted on a common inlet manifold. In selecting this type of design, the potential exists to inadvertently overlook the flow characteristics associated with such a common inlet manifold. The methodology discussed in this paper should effectively model flow through multiple pressure relief devices mounted on common inlet manifolds. This approach ensures accurate representation of flow through each pressure relief device while avoiding the potential pitfalls of taking shortcuts by only analyzing flow through one device.
