Question 1 of 27070

🔍 Key Concepts

• Flash type distilling plant operation compared to a high pressure evaporator • Effect of vacuum on boiling temperature and vaporization • Where and how many times feedwater actually boils in each type of plant

💭 Think About

• Think about what happens to water’s boiling point when pressure is reduced and how flash evaporation works. • In a flash type distiller, does the water sit and boil on heating surfaces, or is it heated first and then suddenly exposed to lower pressure? • Compare the path of the feedwater in both systems: on which surfaces and how many times does it actually go through a boiling/vaporization step?

✅ Before You Answer

• Verify whether flash evaporation depends on a vacuum (reduced pressure) to vaporize hot feedwater. • Check if, in a flash type plant, the feedwater is continuously boiling on tube surfaces or if the phase change takes place mainly when entering the flash chamber. • Confirm whether a high pressure evaporator typically has water boiling on tube surfaces under pressure, and how that differs from the flash type design.
