Process Equipment and Plant Design
The ends of a cylinderical vessel can be closed by a head, which can be one of the four shapes. For the same thickness, choose the one which can withstand the highest pressure.
Plate tower is perferred, if interstage cooling is required to remove heats of reaction or solution
The total weight of a dry plate tower is usually much more than that of a dry packed tower designed for the same duty
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 preferred over packed tower, if the operation involves liquids containing dispersed solids
