To acquire the maximum efficiency in packed column, liquid should be distributed uniformly over the packed bed.Therefore, Liquid Distributors are used above each bed of packing.Good practice designed distributors have following specifications:
Type | Drip Tube Trough Distributor |
Diameter | >1000 mm |
Irrigation Rate | 0.8 – 30 m³/hm² |
Resistance to Fouling | High |
Turndown Ratio | 2:1 (maximum 10:1 in multiple level holes) |
Holes Position | Square pattern punched in the trough’s side which is covered with drip tubes (Multiple levels & series of holes can be punched to achieve high turndown ratio) |
Drip points Density | 80 - 100 drip points/m² |
