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

In an inert gas generation system, a gas scrubber primarily serves the function of cooling the inert gas. When the inert gas is generated, it typically comes out at a high temperature due to the combustion processes involved in its creation. This high temperature can be detrimental to the equipment and overall effectiveness of the system, as well as pose risks in terms of operational safety and efficiency.

Cooling the inert gas helps to bring it to a manageable temperature suitable for further processing or storage. Additionally, by regulating the temperature, the scrubber plays a critical role in ensuring the integrity of downstream equipment and can prevent potential hazards like pressure buildup or damage to gas transport vessels.

The other functions mentioned in the choices do not accurately represent the primary purpose of a gas scrubber in this context. While removing particulate matter, filtering oil vapors, and recovering heat are essential processes in various systems, in the case of a gas scrubber specifically within an inert gas generation setup, the cooling function stands out as the most relevant and critical.
