Q41.
Statement 1: Forward feeding requires pumps for the feed at every step.
Statement 2: In a backward feeding arrangement, the most concentrated feed is exposed to the maximum steam in order to remove heat. This is its advantage.
Discuss
Answer: (d).False, True
Q42.
One disadvantage with backward feeding is that the feed gets very concentrated at the beginning few units itself and hence it’s difficult to feed it to the next evaporator unit.
Discuss
Answer: (b).False
Q43.
Mixed feed arrangement offers the advantage of omitting the usage of pumps by transferring feed in the direction of low pressure. That’s an advantage taken from forward feeding arrangement.
Discuss
Answer: (a).True
