Pick out the wrong statement pertaining to the comparative evaluation of performance of the packed tower and the plate tower.

The total weight of a dry plate tower is usually much more than that of a dry packed tower designed for the same duty

Plate tower is preferred over packed tower, if the operation involves liquids containing dispersed solids

In operations involving large temperature changes. (e.g. distillation), plate towers are preferred over packed towers as the packing may be crushed due to large temperature changes

Plate tower is perferred, if interstage cooling is required to remove heats of reaction or solution

Pick out the wrong statement pertaining to the design of a horizontal tube evaporator.

Liquor flows inside the tube, while the steam is outside submerging the tube

Its usual dimensions are: tube dia = 2-3 cms; evaporator body dia = 1-4 metres and evaporator height = 2.5-4 metres

It is suitable for process, in which the final product is a liquor instead of solid

It is unsuitable for concentrating those liquids, which form a scale or deposit salt
