Question 118General Subjects - Assistant Engineer
70% to passIf the demister used in the device shown in the illustration is improperly installed, which of the following will occur? Illustration MO-0110
AThe vacuum of the device will increase.
BInterstage leakage will cause a decrease in output.
CThe temperature of the device will decrease.
DThere will be an increase of chlorides measured at the distillate pump salinity cell.
AI Explanation
The correct answer is D) There will be an increase of chlorides measured at the distillate pump salinity cell. If the demister in the device shown in the illustration is improperly installed, it can lead to carryover of brine or salt water into the distillate stream. This increased salinity would be detected at the distillate pump salinity cell, resulting in a higher chloride measurement. The other options are incorrect because an improperly installed demister would not affect the vacuum (A), cause a decrease in output due to interstage leakage (B), or decrease the temperature (C) of the device.
