Which of the following conditions will result in an automatic shut down of the flue gas inert gas system?

Correct Answer: Option C — High temperature gas discharge from inert gas blowers.

High temperature gas discharge from inert gas blowers triggers an automatic shutdown to prevent thermal damage to the deck piping and tank coatings. This safety interlock protects the system integrity, as excessive heat indicates a failure in the scrubber cooling water supply or a malfunction in the cooling process.
