Small droplets of water entrained in the flashed vapor produced in a flash-type evaporator are removed by the __________.

Correct Answer: Option D — demisters

Demisters are specialized mesh pads installed in the vapor path of an evaporator. They function by forcing vapor to change direction rapidly, causing entrained brine droplets to impinge on the mesh surfaces and coalesce, effectively separating the liquid water from the pure vapor before it reaches the condenser.
