Effective Emergency Relief System (ERS) design helps companies meet risk-management goals, compliance requirements, and sound business practices. ioMosaic provides a total ERS solution with our comprehensive ERS design services, from reactivity testing for design basis determination to calculations for Z-axis deflection from dynamic loads.
Our team has decades of experience performing PRFS analysis and design.
Our risk-based approach helps mitigate near-unventable scenarios to a tolerable level of risk.
Better evaluate hazards in your facility with an accurate process simulation.
Delivering properly designed pressure relief systems that save both money and time.
Reasonable estimates of the expected time to failure (ettf) or expected time to yield (etty) are required and necessary for effective risk management as well as effective emergency and fire protection and response. Read this paper for a demonstration of calculating ettf or etty in fire exposure scenarios with Process Safety Office® SuperChems™.
Vessels and pipes filled with fluids require pressure relief in order to protect from loss of containment caused by fluid thermal expansion. Thermal expansion of fluids occurs when the fluid is heated as a result of steam tracing, solar radiation, external fire, etc. In addition to establishing the required thermal relief requirements, it is also useful to establish the maximum pressure that can be reached during limited heating for either non-vented or partially vented fluid filled systems. In order to obtain better estimates of the maximum pressure reached, the elasticity of the piping/vessel should be considered. For partially vented systems, the excess volumetric expansion (fluid expansion - vessel/piping expansion) rate will govern the relief requirements.
This PSE module performs efficient tracking of process safety related data and analysis. A customized workflow allows for a specific operating unit or the entire facility to be studied and evaluated for compliance.
A large U.S. company in the oil and gas industry needed to evaluate their protective relief systems in a unit of abnormal operation in which a reactor in a two-stage reactor system was to be bypassed. The client wanted to have the capabilities to safely bypass either of the reactors while not having to shut down the entire unit. Read this case study to find out how we delivered solutions that empowered the client to confidently bypass either reactor without unit shutdown, safeguarding continuous operations.
