🔍 Key Concepts

• Function of air ejectors in distilling plants • Where non-condensable gases tend to collect in a flash-type evaporator system • Difference between flash chambers and condensers/after condensers in the evaporation process

💭 Think About

• In a flash-type evaporator, at what point in the system do steam and vapors give up their heat and condense, leaving non-condensable gases behind? • Are air ejectors more effective when connected to a space with mostly vapor/liquid water, or to a space where condensation is occurring and non-condensables are concentrated? • Think about the term "after condenser" or "distilling condenser"—what is being removed there, and what by‑products are left that must be evacuated?

✅ Before You Answer

• Identify which component is primarily responsible for condensing vapors rather than flashing water into vapor • Determine where non-condensable gases accumulate in a typical evaporator/condensing train • Confirm which of the listed components is normally connected to the suction of air ejectors in marine distilling plant diagrams
