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:
- Uniform liquid distribution
- Operation flexibility through the turn down range
- Low vapor pressure drop
- Low liquid residence time
- Capability to be used as combined with collector for re-distribution
- Minimum distributor height
- Fouling resistance
- Cross mixing capability
