Are you one of 99% engineers who size PSV fire case the wrong way? Sizing PSV fire case seems extremely easy on the surface. You use API 521 to calculate the fire heat input by calculating the wet area, then you get the latent heat from a process simulator, finally you get the reliving mass flow and you follow API 520 to size the PSV area. Sounds easy, right?
Common Mistakes
The calculation sequence seems easy, but it is actually extremely difficult when you get into the details. Common mistakes of 99% engineers are making:
