Plastic Beta, Cascade & Pall Rings

[Need content writeup for Plastic Rings in general]


Odoo - Sample 1 for three columns

Plastic Beta Rings

Plastic Beta Rings have a lower pressure drop aspect ratio advantage due to well-designed additional drip points and increased hole size that leads to uninterrupted flows of gas and liquid.

Applications

  • Air and water coolers in air separation plants

  • Packing towers in the mining, petroleum, chemical and other industries

  • Water-treatment plants

Unique Features

  • Lower pressure drop than pall rings and saddles

  • Structure allows solids to be easily flushed through the bed by the liquid

  • High, free volume passages, independent of orientation

  • Consistent passages for gas and liquid flow

  • Height of the beta ring gives oval reduction in column height in new installations.

  • Higher liquid hold-up, which promotes highabsorption efficiencies due to additional drip points

  • High vapour capacity

  • Mechanically robust

Plastic Cascade Rings

Plastic Cascade Rings represent the majority of operational experience in many processes. They achieve high capacity and efficiency in deep packed beds.

Applications

  • Absorption and stripping services in petrochemical and acid plants

  • Decarbonization and desulfurize systems

  • Synthetic ammonia factories and crude oil separation systems

Unique Features

  • Smaller than a pall ring Reduced resistance when air passes through bed layer

  • Increased free space Low pressure drop High capacity: The low flow rate resistance of the low aspect ratio rings results in a higher capacity

  • Good fouling resistance Low aspect ratio of 1:3 (height of the cylinder is 1/3 of the diameter)

  • Open, cross linked design provides a highly efficient use of the ring’s surface area

  • Robust to variations in liquid and vapour distribution

Plastic Pall Rings

Plastic Beta Rings have a lower pressure drop aspect ratio advantage due to well-designed additional drip points and increased hole size that leads to uninterrupted flows of gas and liquid.

Applications

  • Heat and mass transfer in chemical processing plants, mining and petrochemical industries

  • Air pollution control scrubbers for liquid/gas extraction

  • Water treatment in sewage plants and water supply systems

Unique Features

  • Suitable for low pressure drop, high capacity applications

  • High degree of randomness

  • Consistent ratio of free and blocked passages, independent of orientation

  • Large surface area: volume ratio augments the rate of liquid film surface renewal to improve mass transfer

  • Promotes highly efficient two-phase contact and distribution

  • A relatively high liquid hold-up promotes high absorption efficiencies, especially where the reaction rates are slow

  • Uninterrupted and consistent passages for gas and liquid flow

  • Open, cross linked design provides a highly efficient use of the ring’s surface area

  • Robust to variations in liquid and vapour distribution

  • The internal cross structure of diametrical spars makes it mechanically robust and suitable for use in deep packed beds
