Using split flow, radial flow or cascade flow for column diameter large than 4 ft
All of these
Decreasing the number of rows of caps through which the liquid flows or by decreasing the velocity of liquid flow past the caps or by reducing the distance along the tray through which the liquid must
Providing a higher skirt clearance or a higher weir
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
