Trough-Type Liquid Distributors 

Trough type distributors are normally used in column diameters greater than 1200mm.

Liquid distributors are used above each bed of packing in a packed column to

provide uniform liquid distribution.

The distributor, depending on its design features, is generally located 6 to 8 in.

[150 to 200 mm] above the packing.

The distributor type determines vertical spacing and the proper distance needed

to disengage the vapor phase from the packing before the vapor passes through

the distributor gas passage area.

An ideal distributor has the following attributes, each providing a specific effect

on the overall performance of the packed tower:

•Uniform liquid distribution

•Resistance to plugging or fouling

•Wide operating range

•Low vapor phase pressure drop

•Minimal use of vessel height

•Strength for long life without sagging

NINGBO TCI Trough type distributors are designed to high standards of distribution uniformity,

with emphasis on a uniform pattern of distribution points and minimal variation

of flow among points. They provide distribution quality close to that achieved

in metal high-performance NINGBO TCI Trough type distributors.
