PP PALL RINGS & PP TELLERETTE TOWER PACKING
Manufactured by Plastic Fabricators
Gas and liquid mixing in a packed bed is influenced by the choice of the packed material. Badly chosen packing media will cause high operating costs due to high pressure drop, poor liquid distribution, and poor mass transfer.
To achieve an efficient separation process, the open structure of PP Pall Rings and PP Tellerette Tower Packing ensures that there is enough active surface area with low pressure drop. This ensures efficient gas/liquid flow in the packed bed, resulting in efficient process separation and mass transfer. Plastic Fabricators produces PP Pall Rings and PP Tellerette Tower Packing in one-piece molded form to make sure that you get high-quality and reliable products for chemical processing and pollution control applications. These packing media have good chemical resistance and durability.
TECHNICAL DATA
WHAT ARE PP PALL RINGS & PP TELLERETTE TOWER PACKING?
PP Pall Rings and PP Tellerette Tower Packing are some of the common tower packing media. They are utilized in packed towers in order to maximize the gas-liquid interaction during mass transfer processes in industries. Unlike the tray system, they use thousands of packing pieces in a tower and ensure that there is sufficient area and unobstructed fluid pathways.
Although these two perform similar functions, they have a different geometry.
The PP Pall Ring has a cylindrical geometry which is fitted with windows and support ribs in order to maximize the surface area while preventing any increase in pressure drop.
PP Tellerette Tower Packing has a unique geometry in the shape of a spiral with multiple fingers and curved loops. This improves a very high void fraction along with multi-directional flow which makes them highly efficient in systems that have high gas flow and liquid distribution.
Both products are made from polypropylene and therefore, these are light and resistant to most chemicals.
Why Industries Choose PP Random Tower Packing
COMPLETE PRODUCT RANGE
PALL RINGS VS TELLERETTE PACKING
Random tower packing designs have different flow characteristics.
Pall Rings
Pall Rings are designed with slotted side walls, spacer ribs that increase surface area, and an open flow path. They provide efficient mass transfer while operating over a wide range of conditions.
Tellerette Tower Packing
Tellerette Packing boasts an open spiral design of high void space and multidirectional flow that enhances liquid redistribution while lowering pressure drop. Its design makes it well suited for high capacity scrubbers and gas absorption systems.
PP PALL RINGS
Description
PP Pall Rings offer many advanced benefits over the traditional design, making them the most preferred choice of random packing media amongst chemical process industries. Providing greater liquid distribution without compromising mechanical strength further enhances the utility and performance of the Pall Ring over Raschig Rings.
The windows on the Pall Ring provide even greater liquid distribution by promoting Redistribution throughout the inner and outer surfaces of the Ring. Each window maintains a continuous, open path for free gas flow.
PP Pall Rings are the packing media of choice for applications requiring reliable, safe, and consistent hydraulic performance over a wide range of operating conditions.
Key Features
- Consistent dimension control and elimination of weakened areas from joints or assembled sections are achieved due to the single-mold design.
- The side windows permit liquid to flow through the packing instead of flowing around the packing. This designs achieves complete wetting of the packing surface
- Through innovative design the ribs provide structural support for the ring while permitting increased contact area.
Key Advantages
- High mass transfer efficiency
- Excellent liquid redistribution
- Low pressure drop
- Good mechanical strength
- Lightweight construction
- Corrosion-resistant polypropylene
- Easy tower loading
- Long operating life
- Suitable for new installations and replacement project
PP TELLERETTE TOWER
Description
When high gas throughput and effective distribution of liquids are required, PP Tellerette Tower Packing presents another design of random packing.
Tellerette Packing consists of a number of curved loops stacked radially in a spiral arrangement and provides a useful geometry to achieve a large effective surface area with an open structure.
The design encourages multidirectional flow leading to a decreased tendency to form channels in the packed bed and a more even distribution of liquid on the surface of the packing.
Tellerette Packing has a very good reputation of having excellent hydraulic performance and therefore is commonly used in scrubbers and absorption towers in pollution control systems when a low pressure drop and high capacity for treating gas throughput is of importance.
Key Features
- The shape of multiple curved fingers creates a highly open packing structure which facilitates multidirectional flow.
- The multiple curved surfaces maintain an open structure which helps maintain the flow without creating a restraint to the flow.
Large voids lead to a reduction in hydraulic resistance which results in high gas throughput.
Key Advantages
- Extremely high free volume
- Low pressure drop
- Excellent gas distribution
- Improved liquid spreading
- Reduced channeling
- Lightweight construction
- Corrosion resistance
- Long service life
- Easy installation

WHY PALL RINGS & TELLERETTES PERFORM BETTER THAN CONVENTIONAL PACKING
Cylindrical packing gives a decent amount of surface area; however, the majority of the surface is not utilized as liquid prefers limited pathways whereas gases face unnecessary resistance.
The modern designs such as Pall rings and Tellerettes were invented to address these drawbacks.
- ✓The windows cut in the walls of the rings make sure that liquid flows through the packing rather than around it.
- ✓The inner ribs create extra wetted surfaces but do not restrict the pathway of gases.
- ✓Redistribution of liquid
- ✓Gas/liquid contact
- ✓Hydraulic capacity
- ✓Efficiency of the separation
- ✓Unlike cylindrical packing, Tellerette Packing features an extensively open spiral design.
- ✓Greater open-flow channels
- ✓Higher void volume
- ✓Better gas distribution
- ✓Effective liquid distribution
- ✓Low pressure drop
- ✓Less channeling effect
