Chemical Tower Internals Stainless Steel Water 304 Liquid Distributor
1.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.
2. Technical Parameter 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 |

3. How to choose chemical tower internal water distributor?
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.
Orifice type gravity distributor:
Usually it shows as pan type, deck type or tunnel (trough) type. An orifice pan distributor consists of a pan. There are circular or rectangular risers for vapor flow and perforation for liquid flow in the pan.
Orifice trough type distributors consist of parallel troughs with perforated holes in the bottom for liquid flow. Vapor rises in the space between the troughs. The troughs are often interconnected by cross channels (called as parting box), which help equalize the liquid level in different troughs. This trough type liquid distributors provide more open area for vapor flow and is easier to support.
Orifice type distributor can be designed to have a large number of drip points to provide superior liquid distribution, though it may suffer from corrosion and plugging. Orifices are sized to maintain a minimum liquid head at desired turndown conditions & to avoid distributor overflow during turn up condition. Very small orifice diameters (<4mm) are avoided to prevent fouling.
4.Characteristics distributor:
1.Uniform liquid distribution;
2.Resistance to fouling
3.Proper trundown capabitity
4.Low gas pressure drop;
5. Minimum height;
6.Higher cross-mixing capabity.

Welcome your inquiryStructured Packing specifications.
What types of liquid distributor for choice?
The liquid distributor has various types according to different standard and using conditions. Overall, it has four types.
* Spray nozzles. Hemispherical spray nozzle will distribute the liquids evenly to the random or structured packing bed. There are numerous small holes in 3–10 mm on the nozzle. It is suitable for the smaller diameter packed tower, which is smaller than 600mm.
* Perforated pipe distributor. Single row or double row perforated pipes will evenly distributed the liquid to the packing bed through perforated holes under the pipe. It is widely used in the medium liquid, reduced pressure distillation towers and wire gauze structured packing towers. It can be made into ladder shapes and ring shapes.
* Through distributor. It has through type and through-pan type, which is widely used in the heavy liquid and gas load, high viscosity liquid and liquid with suspended solid.
* Orifice distributor. It can be divided into perforated plate type and pan type. The liquid will flow down through perforated holes or overflow from the annulus between the distributor and the vessel. It is suitable for the small diameter tower, which is smaller than the 800 mm.
