Ball valve leakage - lifetime
Ball valve leakage - lifetime
(OP)
I know the test leak rates c.f. API 6D - but when you do an emission study you have to consider emissions from valves to the flare system - and its common to consider that during plant lifetime valves get worn and leaks more. Initial leak rates is (close to) zero but will amount to something over the years.
If somebody out there could give me a reference (and spare me for test valves i know they are very small) then i would be really happy.
Best regards

RE: Ball valve leakage - lifetime
maybe you can find something in the German Engineers' Guideline VDI 2440 whose Part 4 is about "Determining emissions"...
Hope this helps, 'NGL

try here searching for "2440" here:

You should find the guideline named "Emission control - Mineral oil refineries", dated November 2000 (98 pages, 146 €) with the followin table of contents:
