Question

Advantages and disadvantages of climbing film evaporator

Answer 1

Explanation:

Disadvantages are: high head-room requirements. higher pressure drop through the tubes than in a falling film evaporator.

...

Advantages of the long-tube vertical evaporator are:

reduced floor space requirements.

relatively high heat-transfer coefficients due to partial two-phase flow.

ability to handle foamy liquids.
