Product Description Product DescriptionPP Mass Transfer Media Pall Ring for Stripping ColumnThe ring wall is designed with two rows of windows featuring inward-extending tongue pieces, with 5 tongues per layer. This configuration optimizes gas-liquid distribution and maximizes the utilization of the inner surface. Constructed from metal, plastic, or ceramic, Pall ring packing offers high throughput, low resistance, high separation efficiency, and significant operational flexibility. It is available in three material options: metal, ceramic, and plastic.Pall ring packing represents an advanced filler innovation addressing the limitations of the traditional Raschig ring. By incorporating eight layers of rectangular windows on the ring wall-with overlapping window blades at the center and alternating vertically-it enhances gas-liquid distribution and fully utilizes the inner surface area compared to the Raschig ring.

Also suitable for CO2 degassing towers and ozone contact reaction towers.Ceramic Pall Rings:Used in CO2 degassing towers, acid mist purification towers, and ozone contact reaction towers.Metal Pall Rings:Applied in vacuum distillation columns for heat-sensitive, decomposable, polymerizable, or carbon-forming materials.MaterialsMetal: 304, 316, 316L, carbon steel, 201.Plastic: PP, RPP, CPVC, PVDF, PVC. Packaging & ShippingUsage and CasesDistillation ColumnUsage Method:When installing PP Pall rings in a distillation column, set the packed bed height to 0.5-1 times the column diameter and use a uniform liquid distributor to prevent channeling and maximize separation efficiencyCase:In a petrochemical plant's C4 fractionation column, 38 mm PP Pall rings reduced the reflux ratio by 20% while maintaining 95% product purity, resulting in a 10% energy savingsPurification TowerUsage Method:In water purification towers, use PP Pall rings sized 16-25 mm, with a bed depth of 0.6-1.2 m and an upflow water velocity of 1-3 m/h to prevent clogging and packing carryoverCase:After replacing traditional media with PP Pall rings in a municipal wastewater bio-purification tower, treatment capacity increased by 20%, and effluent COD dropped by 30%FAQ1.
