Q

In a flash evaporator, scale as a result of higher than normal temperatures is most likely to occur in the __________.

🔍 Key Concepts

• Flash evaporator heat flow: where the highest temperatures occur in the system • How scale (mineral deposits) forms in seawater distillation equipment • Difference between feed heaters, vapor separators, and coolers in terms of temperature and phase (liquid vs vapor)

💭 Think About

• Which component in the list normally operates at the highest seawater temperature? • Where is seawater still in the liquid phase and being heated, just before flashing into vapor? • Which component’s normal function would make it least likely to experience scale from overheated seawater?

✅ Before You Answer

• Identify which units are heaters versus which are coolers or separators • Think about where seawater is concentrated brine vs fresh distillate — scale comes from the salty side, not the fresh side • Eliminate any component that mainly handles vapor or cooled distillate, since scale forms where hot seawater/brine contacts hot metal surfaces
