70% to pass

Which of the listed functions is the purpose of a gas scrubber in an inert gas generation system?

A Cools the inert gas.
B Maintains the oxygen content at 5% by volume.
C Maintains flow to the water seal on the gas main.
D Bleeds off static electricity in the inert gas.
AI Explanation

The correct answer is A) Cools the inert gas. The purpose of a gas scrubber in an inert gas generation system is to cool the inert gas before it is distributed to the cargo tanks. This is necessary to prevent the cargo tanks from being exposed to high-temperature inert gas, which could damage the tanks or pose a safety risk. The gas scrubber lowers the temperature of the inert gas to a safe and appropriate level for the cargo tanks. The other answer choices are incorrect because they do not describe the primary function of a gas scrubber. Maintaining the oxygen content, flow to the water seal, and bleeding off static electricity are not the main purposes of the gas scrubber in an inert gas generation system.
