Above I have a photo of a system. Nitrogen header pressure is used to transfer liquid from storage vessel to reactor vessel. The piping system is set up where the header is ran above walkways...
Recently a new engineer oversized a control valve for a water inlet to a funnel pot where no tuning allows for effective control of flow. Usual operating flows would like to be from 15 gpm to 50 gpm, but the valve simply cannot control anywhere near the lower end of the flow requirements...
For the sake of simplifying as much as possible, assume there is a closed pressure vessel (650 gals) that takes water from a water distribution header. This header is at 100 psig and regulated down to 40 psig and blocked off by a block valve right before the pressure vessel. If we assume the...
