Small droplets of water entrained in the flashed vapor produced in a flash-type evaporator are removed by the _______________.
AI Explanation
The correct answer is B) demisters.
In a flash-type evaporator, small droplets of water entrained in the flashed vapor are removed by demisters. Demisters are devices designed to separate and remove fine water droplets from the vapor stream, preventing them from being carried over into the condensers. This is an important function to ensure the quality and purity of the distilled water produced by the evaporator.
The other options are incorrect because: Condensers are used to condense the vapor, not remove the entrained droplets. Splash baffles are used to prevent liquid carryover, but not specifically for removing fine droplets. Spray pipes are used to distribute the feed water, not to remove the entrained droplets.
