This makes this type of distributor highly resistant to fouling and expands the scope of application. A trough type distributor consists of a pre-distribution trough or ‘parting-box’ mounted above a number of equally spaced, narrow troughs.
Trough type distributor construction can be used for very high liquid load & higher column diameter from 900 mm & above diameters.
Both bottom holes & tube construction is possible in trough type distributor. Top trough distributor the liquid in bottom channels which distribute the liquid evenly on the surface of packing.
Can be used for both structured & random packing. Liquid loads may vary from 2m3/m2hr to 50 m3/m2hr.
The simplicity of this design helps to get good seating, better leveling& easiness of installation.
