PP Teller Rosette Ring: Cost-Effective Random Packing for Corrosive Service Product Highlight: The PP Teller Rosette Ring delivers void fractions up to 98% with bulk densities as low as 90 kg/m³. Its three-dimensional radial geometry eliminates channeling and wall-flow, making it the economical choice for FGD scrubbers, acid gas absorption, and chemical separation towers. 1. What Is the PP Teller Rosette Ring? The Teller Rosette Ring is a proprietary random tower packing consisting of multiple small rings arranged radially into a flattened spherical body. When molded from Polypropylene (PP), it becomes a lightweight, corrosion-resistant, and highly cost-effective solution for gas-liquid contacting in neutral to mildly aggressive chemical environments. The open radial structure ensures uniform liquid distribution across the entire tower cross-section, significantly reducing the risk of channeling that plagues conventional ring packings. Figure 2: Radial small-ring arrangement eliminates dead zones and promotes uniform wetting. 2. Technical Specifications PP Teller Rosette Rings are available in three standard sizes. Key performance data is shown below: Dimensions (mm) Surface Area (m²/m³) Void Fraction (%) Bulk Number (pcs/m³) Bulk Density (kg/m³) 25 × 9 195 82 170,000 90 47 × 19 185 88 32,500 111 51 × 19 180 98 23,500 — Material: Polypropylene (PP). Service temperature range: -60°C to 150°C (consult factory for high-temperature applications above 100°C). 3. Key Performance Advantages Why Choose PP Teller Rosette Over Standard Random Packings? Ultra-High Void Fraction (up to 98%): The open radial framework minimizes gas flow resistance, allowing higher throughput at lower pressure drop than Pall rings or saddle rings. No Channeling or Wall-Flow: Three-dimensional geometry forces liquid to spread evenly, maximizing effective wetting area and mass transfer efficiency. Excellent Chemical Resistance: PP withstands most inorganic acids, alkalis, and salt solutions at moderate temperatures. Lightweight: Bulk density of just 90–111 kg/m³ reduces structural load on tower supports and makes handling effortless. Cost-Effective: Injection-molded PP offers the lowest total installed cost among all corrosion-resistant random packings. 4. Primary Applications • Flue Gas Desulfurization (FGD): SO2 and SO3 absorption scrubbers in power plants and refineries. • Acid Gas Scrubbing: HCl, Cl2, and H2S removal from exhaust streams. • Chemical Processing: Neutralization towers, salt recovery, and general-purpose absorption columns. • Chlor-Alkali: Brine purification and chlorine washing systems. • Gas & Oil: CO2 and H2S sweetening, gas cooling, and dehydration.

A: Standard PP grades are rated up to 100°C. For service between 100°C and 150°C, we recommend RPP (reinforced polypropylene) or switching to PVDF. For highly oxidizing acids at any temperature, PTFE is the correct choice. Q: How many pieces do I need for my tower? A: Use the bulk number from the table above. For example, a 2 m ID tower with 3 m bed height of 51mm rings: π × 1² × 3 × 23,500 ≈ 221,700 pieces. Contact us with your tower dimensions for a precise quote. Q: Can PP Teller Rosette Rings handle hot concentrated acids? A: PP is suitable for most cold-to-warm acid services but degrades in hot concentrated H2SO4 or HNO3. For aggressive acid gas at elevated temperatures, we recommend PTFE or ceramic packings. Our engineers can help you select the right material.
