Process Equipment and Plant Design
The operating velocity in the absorption tower is usually 40-50% of the flooding velocity. Packed absorption towers are normally designed for a pressure drop of about __________ mm of water column per metre height of packing.
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
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 perferred, if interstage cooling is required to remove heats of reaction or solution
