During operation which device listed removes air and non-condensable gases from the unit shown in the illustration? Illustration MO-0111
⢠Function of an air ejector or vacuum pump in a separator system ⢠How nonâcondensable gases are removed from a closed vessel under vacuum ⢠Tracing the piping from items 21, 22, 25, and 27 to see where they lead
⢠Look at how each numbered item is connected: which one ultimately discharges to atmosphere or a vent line rather than to liquid in/out lines? ⢠Which device would need to operate continuously (or intermittently) to keep the bowl housing free of air so vacuum and proper separation can be maintained? ⢠Compare the symbols: which item is drawn as a pump/ejector versus a simple valve, gauge, or vent fitting?
⢠Verify which component is connected to the top of the separator housing (24) where gases would accumulate. ⢠Confirm which line from the candidate device leads to a vent/overboard or condenser and not back into the process fluid. ⢠Check that the chosen number is associated with a gasâhandling device (ejector, vacuum pump, or vent) rather than a liquid pump or manual valve.
