Which function is NOT provided by the scrubber of an inert gas system?

Correct Answer: Option B — Maintains gas pressure in the tanks.

Inert gas scrubbers are designed to cool the hot flue gas, remove over 90% of sulfur dioxide, and filter out particulate matter like soot. Maintaining system pressure is the function of the inert gas blowers and the pressure-regulating valves, not the scrubber unit itself.
