In a flash evaporator, scale as a result of higher than normal temperatures is most likely to occur in the _______________.
AI Explanation
The correct answer is D) salt water feed heater.
In a flash evaporator, scale formation is most likely to occur in the salt water feed heater due to the higher temperature in that component. The salt water feed heater is responsible for preheating the incoming salt water feed, which increases the likelihood of mineral deposits and scale buildup at those elevated temperatures. The other components, such as the second-stage vapor separator, second-stage feed heater, and distillate cooler, operate at lower temperatures, making them less prone to scale formation.
