Which of the following conditions can cause high salinity of the distillate due to sea water leakage in the illustrated device? Illustration MO-0110
AI Explanation
The correct answer is D) Failure to properly tighten the bolts of the condenser heat exchanger.
If the bolts on the condenser heat exchanger are not properly tightened, it can allow seawater to leak into the distillate, resulting in high salinity. The condenser is the part of the distillation system that cools the steam back into liquid freshwater. Improper sealing here could allow seawater to contaminate the freshwater output.
The other options are incorrect because they do not directly relate to seawater leakage into the distillate. Improper venting during start-up or operation (A and B) would not cause seawater contamination. Failure to tighten the evaporator heat exchanger (C) would not affect the condenser and the freshwater output.
