1. Absorption tower trough liquid distributor
Liquid distributors to be used in applications where there is less demanding on packing performance. For example, heat transfer applications, stripping and absorption services.

2. Absorption tower trough liquid distributor structure:
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.
3. Absorption tower 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.
