Towers - Mechanical Parts and Functions

Mechanical Parts of the Tower and their Functions

1. Feed Inlet Nozzles

These are used to direct the feed into the proper level of the tower in order to give the most efficient operation.

2. Trays

The trays are used to give maximum fluid contact inside the tower. This produces the most efficient end product.

3. Downcomers

The downcomers direct the fluid from one tray to the next lower tray in the tower.

4. Weirs

The weirs are "walls" which keep the correct level of liquid on each tray. The rising vapours must pass through the liquid on the trays. This gives good contact between the liquids and the vapours.
