1. Trough liquid distributor introduction,
Liquid distributor is the most important column internal from a
process point of view. It is required to distribute liquid
uniformly at the top of packing tower. Meanwhile a liquid
distributor must have sufficient gas passage area to avoid high
pressure drop or liquid entrainment.
2. Choice of liquid distributor:
Column Diameter mm | Specific liquid load M3/m2*h | System fouling tendency | Turndown ratio | Suitable type of liquid distributor |
| 250 - 900 | 0.75 - 5 | Low - medium | ＜10:1 | Trough type liquid distributor with sump Deck type liquid distributor with orifices on drip tubes |
| 5 - 30 | Low - medium | 2:1 | Pan type liquid distributor Trough type liquid distributor with sump |
| ＞30 | Low - medium | 2:1 | Pan type liquid distributor Trough type liquid distributor with sump Deck type liquid distributor |
| ＞900 | 0.75 - 5 | Low - medium | ＜10:1 | Trough type liquid distributor with parting box Deck type liquid distributor with orifices on drip tubes |
| 5 - 30 | Low - medium | 2:1 | Trough type liquid distributor with sump Trough type liquid distributor with parting box Deck type liquid distributor |
| ＞30 | Low - medium | 2:1 | Deck type liquid distributor Trough type liquid distributor with sump |
3. Liquid distributors classification:
Usually there are pressure type liquid distributors and gravity
type liquid distributors.
Pressure type liquid distributor:
It provides more open area for vapor flow. Often it is less
expensive, lighter, less robust and requires smaller lead up piping
than gravity type liquid distributor. On the other hand, it
requires high operating cost, susceptibility to plugging, corrosion
and a relatively inferior quality. One example of pressure liquid
distributors is pipe arm and spray type liquid distributor.
4. Trough liquid distributor characteristics:
Liquid distributor is the most important column internal from a
process point of view. It is required to distribute liquid
uniformly at the top of packing tower. Meanwhile a liquid
distributor much have sufficient gas passage area to avoid high
pressure drop or liquid entrainment.
Characteristics of an ideal liquid distributor:
Uniform liquid distribution; Resistance to fouling; Proper trundown
capabitity;Low gas pressure drop; Minimum height; Higher
cross-mixing capabity.
