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

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

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

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