Amplify Your Process Safety

In Episode 45, we covered the basics of piping requirements for pressure relief devices. In this episode, Rob is joined by Eric Hirsch, to take a deeper dive into pressure relief device concepts. Eric, a principal process engineer at Nexus Engineering Group, works in process design with a focus on pressure relief devices. In this episode, Eric and Rob cover basic requirements for pressure relief devices and the calculations that go with them. You'll learn about back pressures, considerations for common subheaders and global relief scenarios, impacts to the relief capacity of a system, identifying fire zones/circles, design issues with flare knock out pots, Eric's thoughts on the use of rupture disks for overpressure protection, SIS instrumentation, designing for 2-phase relief, and more. Then Eric gives his expert advice regarding a frequently asked question: Do I have to have overpressure protection on every pressure vessel and/or piping system and do I need calculations for all of those? He'll touch on what could get you in trouble with OSHA during an enforcement audit when it comes to your pressure relief scenarios, how often you should revalidate them, and more. Don't miss this content-packed episode from an expert on pressure relief devices.
