Plastic conjugated ring packing can be suitable for high-gas-load scrubbers because its open three-dimensional geometry provides relatively large gas-flow passages while maintaining gas-liquid contact. The design can help reduce hydraulic resistance and provide greater operating margin before flooding, but final selection must still consider packing size, liquid rate, fouling, distributor performance, process chemistry, and required mass-transfer efficiency.

Ceramic Y-Type Partition Ring replacement should match the existing packing by nominal size, actual dimensions, wall thickness, surface area, void fraction, bulk density, pieces per cubic meter, dry packing factor and ceramic specification. The verified series shows strongly non-linear size behavior: 38 to 50 mm reduces element count sharply while dry bulk density rises slightly, and 50 to 80 mm reduces void fraction from 75% to 70% while dry packing factor rises from 233 to 262 m⁻¹. The largest model is therefore not automatically the most open or lowest-factor option.

Ceramic Cascade Mini Ring replacement should match the existing packing by model, actual dimensions, wall thickness, surface area, void fraction, bulk density, pieces per cubic meter, dry packing factor and ceramic specification. Across the verified 25–76 mm series, element population falls by about 96.5% while bulk density falls only about 18.5%, showing why pieces per cubic meter cannot be used to estimate packed-bed weight. Larger models provide higher void fraction and lower dry packing factor, but at the cost of substantially lower geometric surface area.

Ceramic Intalox Saddle replacement should match the existing packing by family, nominal size, wall thickness, surface area, void fraction, bulk density, dry packing factor and ceramic specification. The verified series shows strongly non-linear size behavior: void fraction decreases from 19 to 25 mm and again from 38 to 50 mm, while moving from 50 to 76 mm leaves voidage unchanged at 77% and reduces dry packing factor by only about 2.3% despite a roughly 21% loss in surface area. The referenced catalog does not provide verified pieces per cubic meter for Standard Ceramic Intalox Saddle, so that value should not be fabricated or borrowed from another saddle series.

Ceramic Super Intalox Saddle replacement should match the existing packing by size, wall thickness, surface area, void fraction, packing population, bulk density and ceramic specification rather than nominal size alone. The 38 and 50 mm models demonstrate why: both have 80% catalog void fraction, yet their surface area and pieces per cubic meter differ substantially. The verified DAIER dataset does not provide dry packing factor for this series, so that parameter should not be estimated or borrowed from Standard Ceramic Intalox Saddle.
