Product Description
Liquid Distributor
From a process point of view liquid distributors are the most important column internal devices. A distributor is required to uniformly distribute liquid at the top of a packed tower.
Liquid distributor must provide sufficient gas passage area to avoid a high pressure drop or liquid entrainment.
Selection 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 |
For clean systems with standard turndown, we use perforations at the bottom of the distribution troughs;
For low liquid loads and wide operating ranges, we often use Orifices, weirs or attached distribution pipes on the sides of individual troughs;
For systems where the risk of fouling exists, Overflow distribution (e.g. via weirs on trough sides) is arranged.
Overflow drip pipes where the risk for fouling exists.
Spray nozzles are adopted particularly for pipe type distributors for solid- free systems

Company Profile
Our main business runs around columns / towers, which are widely used in oil refinery, petrol-chemical industry, chemical industry, pharmacy, fertilizer industry, etc. With the customers’ requirement for full series of tower internal products, we are working with famous universities in related area, and developing our capacity in tower internal designing, manufacturing and service. We can now design, produce and supply liquid distributor, liquid collector and re-distributor, structured packing support, random packing support, bed limiter, chimney trays, etc.
With many advanced machines and skilled workers, we also provide custom fabrication service. It can be wire mesh or steel plate products, or something like that. Show us your drawings or tell us your ideas, we will try to make the special products for you.
