While standing watch underway at sea, you notice salinity carryover in the low pressure distilling plant. This can be a result of __________.

🔍 Key Concepts

• Operation of low pressure distilling plants and what causes salt to pass into the distillate • Difference between mechanical/operating faults vs water quality measurements (like conductivity) • How pressure and flow conditions in the evaporator and separators affect carryover

💭 Think About

• Which choice describes a condition that would actually cause salt water to get carried over with the fresh water, rather than just measuring or treating it? • Think about how a pressure drop or low steam pressure might change boiling and separation inside the evaporator—would that make carryover better or worse? • Which option is clearly an effect (a result you would see on an instrument) instead of a root cause of salinity carryover?

✅ Before You Answer

• Identify which options describe causes (changes in plant operation or pressures) vs which describe symptoms or test readings • Consider how loop seal pressure conditions affect the separation of brine and vapor in a flash-type or low pressure evaporator • Eliminate any option that would normally be associated with improved distillate purity rather than increased salinity carryover

Question 1 of 27070

While standing watch underway at sea, you notice salinity carryover in the low pressure distilling plant. This can be a result of __________.

insufficient chemical feed

a pressure drop through the loop seal

below normal steam supply pressure

low distillate conductivity
