Oil & Gas Process Safety Seminar
Best Practices in Relief and Blowdown System Design
High-fidelity analysis is taking an increasingly central role in safe and cost effective design of pressure relief, blowdown and flare systems in the oil and gas industry.
As leaders in the application of advanced analysis to safe design of relief and blowdown systems and active members of the API Pressure relieving sub-committee, PSE will present best practice approaches which are fully compliant and highlight the anticipated changes to industry Standards like API 520 and 521.
This seminar describes how distributed modelling approaches for blowdown, can accurately calculate minimum metal temperatures (MDMT) in specific locations, both within the process segment and flare piping, enabling the correct material choices. Updated industry standards, including the 6th edition of API 521, now require an analytical methodology to consider vessel stress and vessel survivability during blowdown. Industrial case studies shared here demonstrate how this rigorous analysis can help make informed design decisions.
Verification of Pressure Relief Devices is an ongoing requirement of PSM, and is ‘built-in’ to the design process in many organisations. PSE brings skills in dynamic assessment to commonly encountered problems when API methodology results in undersized valves, and by way of project examples has been proven to reduce the need to change out valves.
Vibration based failures have been of increasing concern in relief and flare systems, and the guidelines and methodology for assessing this is still developing. We show a project example of the recommended approach using the EI guidelines and advanced FEA analysis used to provide mitigations.
