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

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

Section "F" serves as the condenser and air ejector section. Here, the vapor produced in the flash chamber is condensed into distillate. Simultaneously, non-condensable gases are separated and removed from the system to maintain the required vacuum, ensuring the evaporator operates at the design efficiency for optimal water production.
