Trough Liquid Distributor duplex 2205 plate anti - corrosion
1. Trough liquid distributor,
Hualai factory can help you make various types of liquid distributor. We can make the liquid distributor into almost any sizes, from 300mm, for example, to 9000 mm. The material available for trough liquid distributor include stainless steel 304, 304L, 316L, 410s, 2205, 2507, etc.
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. How to choose liquid distributor?
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.
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.
When we need to select a liquid distributor, we need to consider the tower diameter, flow rate, turndown ratio, available height (in case of revamp) and fouling resistance.
Weir type gravity distributor:
Generally speaking, the weir type gravity distributor is one of the least troublesome distributors. It has excellent trundown capability and can handle large liquid load. However it can usually provide only a limited number of drip points (minimum 30 number of weirs per m2). It is also extremely sensitive to levelness and liquid surface agitation.
4. 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.
