Question 94General Subjects - Assistant Engineer

The correct answer is D) carryover in the first-stage. A high salinity reading at the salinity cell located in the loop seal between the two stages of a flash type evaporator would indicate carryover of brine from the first-stage to the second-stage. This occurs when the brine level in the first-stage is too high, causing excessive entrainment of brine droplets into the vapor that is fed to the second-stage. This carryover contaminates the freshwater being produced in the second-stage. The other answer choices are incorrect because: A) A high salinity reading is not indicative of a faulty brine overboard pump. B) Chill shocking is used to remove scale, not to address carryover issues. C) A high salinity reading would not directly indicate a leak at the second-stage condenser.
