Duplex 2205 Anti Corrosion Tower Internals Liquid Distributor

1.Liquid distributors

Liquid distributors is installed upper of the random packing. It is important to get even distribution of water or other liquid.

Liquid distributors have many types such as trough type,pan type,deck type,channel type and pipe type.

2. Choice of liquid distributor:

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.
