Advantages of Sieve Trays :

Good operating effectiveness,
Simple design
Low cost and easy maintenance .
Be resistant to heavy fouling services and offering high capacities.

Disadvantages of Sieve Trays :

Low flexibility
Low to moderate performances.

Advantages of Dual flow trays:

Vapor rate maintains the plate liquid level and the hole size will be defined for optimizing the performance.
When dual flow trays have high open area,capacity tend to be higher and pressure drop tend to be lower, being particularly suitable for containing a moderate to high solids content
