Chance17,
pressure regulators(Mechanical devices) are parallel and according to company design criteria, we must design this PSV for failing of 2 regulators.
But why we should design upstream valves for rated flow when there is not any possibility for providing this flow rate by any source?
I am designing PSV for a fuel gas scrubber,
Governing case is gas blow-by through two pressure regulators (PCV)upstream fuel gas scrubber. Flow through these two valves is two-phase and gas and liquid are separated in fuel gas scrubber therefore I only considered gas portion of flow through...
am Using Flarenet software for design of an offshore platform vent network, In this software, there is two terms for pressure:
Static back pressure;
Total back pressure;
In Flarenet , I can change pressure term in preference section to Static pressure or total pressure;
---1st I want to know...
