I will do psv sizing, relief load and flare system calculations

Pressure safety valves protect people and plant, so the numbers must be right. I prepare complete relief and flare calculations that stand up to client and third-party review.

Scope:

- Relief scenario identification: blocked outlet, fire case, cooling failure, control valve failure, tube rupture, power failure

- Relief load calculations for vapour, liquid and two-phase cases

- PSV orifice sizing and selection to API 520 Part I

- Inlet pressure loss (3% rule) and built-up/superimposed back pressure checks

- Fire case heat input and wetted area to API 521

- Flare header loads, tail pipe Mach number and back-pressure screening

- Tank breathing and emergency venting to API 2000

You receive Excel calculations, a relief scenario matrix, PSV datasheets and a clear report showing the governing case for each valve.

I have reviewed real refinery flare and blowdown studies, so I know what reviewers look for.
