Process Equipment and Plant Design
The average velocity in the tubes of a 1-4 heat exchanger is __________ times that in 1-1 heat exchanger having the same size & number of tubes and operated at same liquid flow rate.
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
Plate tower is perferred, if interstage cooling is required to remove heats of reaction or solution
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
