Role of components in Hydrogen Electrolyzer

A: A: That's the job. You're looking at mist carryover, not bulk phase split. B: Cell-level separation is handled inside the stack; this assumes a different architecture. C: MAWP step-down doesn't come from this vessel; check the P&ID pressure class notes. D: Partial pressure control happens via flow and differential pressure control, not this drum.

A: A: The hatching and thickness callout point to a mist eliminator, not a plate. B: Baffles are drawn as plates with supports; no thickness callout like this. C: Corrosion allowance isn't drawn as an internal feature; it's a calculation note. D: Flame arresters sit in piping, not free inside a separator shell.

A: A: Higher H2 pressure drives crossover through diaphragm defects; that's the hazard chain. B: Efficiency loss happens, but it doesn't capture the safety exposure. C: Evaporation effects are slow and secondary, not tied to this failure. D: This flips the physics; pressure gradient worsens back-diffusion.

A: A: Plugging raises ΔP without hurting drying performance at first. B: Exhausted media hits dew point before ΔP spikes. C: Bad analyzer doesn't explain a real hydraulic change. D: Higher flow would move both ΔP and dew point together.
