Please download the Fire PSV Sizing Calculation Spreadsheet using following link.


Calculation: According API-RP-521

Validation Example: Crosby Engineering Handbook, Page 7-22, Example1

I am still working to improve this spreadsheet but it is a good starting point. You can get further detailes on calculation and validation in Crosby Engineering Handbook.

PSV sizing for external fire is a dynamic case. I recomebd you to use process simulator such as HYSYS which has a specific utility for vessel depressusring during fire. You have to provide equipment details under fire and orifice size or final pressure.

You can use the GPSA Handbook for fire sizing (section 5-12). They have a good explanation. Hope that can help a bit while someone can upload a sample spreadsheet. Cheers...
