Trough Liquid Distributor design, manufacture, shipment and installation

 

 

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:

3How to choose liquid 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. 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.
