Rapid fluctuations of absolute pressure in the last effect of a multi-effect submerged tube distilling plant will tend to cause __________.

🔍 Key Concepts

• multi-effect distilling plant operation and purpose of the last effect • relationship between pressure changes, boiling, and entrainment/priming • how pressure stability affects scale formation, foaming, and pump operation

💭 Think About

• In the last effect, what happens to the boiling behavior of the brine if the absolute pressure jumps up and down quickly? • Which of the listed effects would most likely be caused by liquid carryover (entrained droplets) rather than just temperature change? • If conditions are unstable in the last effect, would that realistically improve or worsen the performance of downstream equipment like the brine and distillate systems?

✅ Before You Answer

• Compare which choices would lead to worse distillate quality versus better quality when boiling is erratic • Ask whether rapid pressure fluctuations are more likely to stabilize or destabilize the liquid surface in the evaporator • Eliminate any option that suggests improved or slight changes when the condition described is clearly severe and disruptive
