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®.
The landscape of relief systems and general process safety management compliance is evolving. This evolution is due in part to enforcement or potential enforcement of recognized and generally accepted good engineering practices (RAGAGEP). Because of RAGAGEP considerations, oversizing a relief device is no longer acceptable or desirable from an engineering perspective and from a legal liability perspective. For example, recent citations and enforcement by OSHA have considered the lack of toxic/flammable dispersion analysis and the lack of thermal radiation analysis for releases going directly to atmosphere. Other considerations include explosion risk, relief piping vibration risk, runaway chemical reactions, PRV stability, embrittlement due to cold temperatures, metal failure due to overheating 1, multiphase flow, etc. The evaluation and/or design of emergency relief, vent containment, and flare systems require deep expertise and specialization. Many facilities place their trust in their engineering contractors to possess that deep level of expertise and to provide them with safe and compliant designs and evaluations. This paper contains case studies of why dynamics are needed in relief system evaluations for the most effective risk reduction from an overall or a lifecycle perspective.

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.
