Product Feature
1. Complete Elimination of Wall Flow and Restoration of Mass Transfer Efficiency
The AYRTTER Liquid Redistributor employs a full-section collection design, completely capturing and mixing both the wall flow along the column wall and the main flow in the central region, fundamentally eliminating the wall flow accumulation effect. After redistribution, the mass transfer efficiency of the lower packing layer can be restored to over 95% of the initial stage.
2. Thorough Liquid Mixing and Elimination of Concentration Gradients
In the upper packing layer, due to the gradual change in vapor-liquid equilibrium, differences in liquid concentration may exist at different radial positions (concentration gradient). The liquid collection zone within the redistributor provides ample mixing space, ensuring uniform mixing of liquids of different concentrations and preventing the concentration gradient from propagating downwards.
3. Dual Gas-Liquid Distribution Capability (Slotted Type)
The AYRTTER slotted redistributor, while completing liquid collection and redistribution, can also redistribute rising gas through a riser structure, eliminating gas flow deviation. This function is particularly important for systems with high gas-phase mass transfer resistance.
4. Wide operational flexibility, adaptable to load fluctuations
Like distributors, redistributors need to adapt to fluctuations in the operating load of the unit. The AYRTTER redistributor uses a gravity-type liquid distribution structure, maintaining stable redistribution performance within a range of 30%–120% of the design load, with an operational flexibility of over 4:1.
5. Strong anti-clogging capability, easy maintenance
The redistributor's liquid channel design is spacious (distribution orifice diameter ≥8mm, or an overflow weir structure), providing excellent anti-clogging capability for media containing solid particles, easily polymerizing, and prone to scaling. Even if individual distribution orifices become clogged, adjacent orifices can handle the excess flow, resulting in minimal decrease in overall distribution uniformity.
6. Robust structure, suitable for large tower diameters
Redistributors are typically installed at packing sections and need to support the weight of the upper packing and themselves. The AYRTTER redistributor uses a high-strength metal structure, equipped with support beams or legs, ensuring long-term stable operation. The modular design allows for segmented manufacturing and on-site assembly, suitable for various towers with diameters from 300mm to 12000mm and above.
7. Diverse Material Options, Suitable for Various Corrosive Conditions
AYRTTER Liquid Redistributor can be made from a variety of metallic materials to suit different media environments.
Typical Operating Conditions Requiring a Redistributor
Total packing height exceeds recommended segment height
Large tower diameter (>2000mm), significant wall flow phenomenon
High separation requirements, necessitating maximum mass transfer efficiency
Large operating load fluctuations, requiring a wide flexible distributor
The medium is prone to generating radial concentration or temperature gradients
Modification project, existing tower efficiency is insufficient
