Which of the following conditions occurs in the section labeled "F" of the device shown in the illustration? MO-0110

Correct Answer: Option D — The vapors produced in section "G" are condensed and the non-condensable gases are removed.

Section F functions as the condenser stage. Here, the water vapors generated in the flash chamber are cooled by the incoming seawater, causing them to condense into distillate. Simultaneously, the system removes non-condensable gases to maintain the vacuum necessary for continuous, efficient evaporation and distillation.
