The lessons learned from the 1987 Grangemouth hydrocracker explosion and fire are still relevant today. Too often we have seen engineers underestimate the consequences of overpressure or too heavily rely upon human controls.
In this newsletter, you'll find an excerpt from a presentation by Daniel Wilkes on modelling dynamic vapor breakthrough and why more rigorous methods can reduce relief requirements.
He’ll cover:
Bonus!
This newsletter also includes a 26-minute video on flow dynamics modelling, a branch of fluid mechanics that deals with the prediction and analysis of fluid flow in various systems.
Vapor breakthrough scenarios should be carefully considered since they are frequently the sizing case for pressure relief system and flare (PRFS) design, as they have been known to be handled improperly. In some cases, the sizing credits were applied incorrectly. In others, the scenario went completely unnoticed in the hazard analysis.Have a great and safe day.
