Liquid distribution
INTALOX® high performance distributors are designed to provide a uniform drip-point pattern and uniform point-to-point flow to the packing below. As a result, INTALOX high performance distributors are recommended for:
- Distillation services
- With high stage count per bed
- That are operating near the minimum reflux ratio or close to an equilibrium pinch
- Distillation systems
- With low relative volatility
- With high purity product
- Absorption or stripping applications with close approach to equilibrium
- Heat transfer applications with close approach temperatures
Koch-Glitsch “traditional” liquid distributors have less uniform distribution patterns and liquid flow than the INTALOX high performance distributors. The standardized construction of these distributors make them a more economical alternative for less demanding services, typically in conjunction with a conventional random packing.
Liquid redistribution
Redistribution of liquid between packed beds improves efficiency. There are several reasons to separate a single packed bed into two packed beds and redistribute the liquid:
- Feed introduction
- Product side draw
- High transfer unit count
- Desire to cross-mix the liquid to ensure even liquid concentrations across the bed.
- Prevention of liquid maldistribution
- Physical weight of the packed bed
