Pick out the wrong statement pertaining to the design of a horizontal tube evaporator ?
Correct answer: C. Liquor flows inside the tube, while the steam is outside submerging the tube
- A. It is unsuitable for concentrating those liquids, which form a scale or deposit salt
- B. It is suitable for process, in which the final product is a liquor instead of solid
- C. Liquor flows inside the tube, while the steam is outside submerging the tube
- D. height = 2.5-4 metres
- E. Its usual dimensions are: tube dia = 2-3 cms; evaporator body dia = 1-4 metres and evaporator
Explanation
In a horizontal-tube evaporator, steam generally flows inside the horizontal tubes and the liquor remains outside, where it is heated by condensation. Therefore, the statement reversing these flow locations is the wrong one.
