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™.
Recent emphasis on RAGAGEP increased the scope of relief systems risk factors that require evaluation in order to develop complete and compliant Pressure Relief and Flare Systems (PRFS) documentation. Failure to comply with RAGAGEP ((d)(3)(ii)) is the most cited element of the PSM requirements. This paper discusses how RAGAGEP considerations now require evaluation and proper documentation of risk factors that are often overlooked including but not limited to: dispersion analysis, thermal radiation, noise, vibration risk, reaction forces and structural supports, metal cold temperatures due to expansion cooling and two phase flow, hot temperatures due to fire exposure and/or runaway reactions, PRV stability, chemical reaction systems, and loss of high pressure/low pressure interface. Important RAGAGEP considerations for these additional risk factors are highlighted and discussed. Recommendations are provided on how to best address these factor in the evaluation and documentation of design basis.

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 major petroleum company recently increased production capacity and required an analysis of its existing relief systems to validate performance and design. As a result of increasing production capacity and debottlenecking studies, several refinery units were found to be operating at charge rates higher than the design basis for the relief systems documentation.
