Polypropylene Pall Ring Real Application Cases
Acid Mist Scrubber / HCl Waste Gas Absorption Tower – Chemical Plant
Process: Wet scrubber for hydrochloric acid mist removal Packing
Media: 50mm Polypropylene Pall Ring
Working Condition: Temperature ≤75℃, caustic soda circulating washing, corrosive acid gas
Project Result: High void structure of polypropylene pall ring ensures low pressure drop. HCl removal efficiency reaches over 99%. The PP material resists acid corrosion and avoids rust problems compared with metal packing. Long service life and low maintenance cost. Suitable for continuous 24h operation of chemical workshop tail gas treatment.
SO₂ Flue Gas Scrubber – Fertilizer & Sulfuric Acid Plant
Process: SO₂ tail gas absorption tower Packing
Media: 76mm Polypropylene Pall Ring
Working Condition: Flue gas scrubbing with sodium alkali solution
Project Result:
Polypropylene pall ring improves gas-liquid mixing evenly. System stably controls SO₂ emission below local environmental standard. Under the same gas flow, pressure drop is much lower than Raschig ring, saving fan power consumption. Large flux capacity to handle high-volume flue gas.
Ammonia Stripping Tower – Landfill Leachate / Wastewater Treatment
Process: Ammonia nitrogen stripping for wastewater
Packing
Media: 38mm Polypropylene Pall Ring
WorkingCondition: Alkaline wastewater, air stripping process
Project Result:
Polypropylene pall ring provides large gas-liquid contact surface. Ammonia stripping efficiency improved obviously. Light weight and anti-clogging performance reduce bed fouling. Widely adopted in municipal wastewater, landfill leachate and industrial wastewater ammonia removal projects.
VOC & Organic Waste Gas Absorption & Solvent Recovery – Fine Chemical / Pharmaceutical Factory
Process: Organic solvent absorption and recovery tower
Packing
Media: 25mm Polypropylene Pall Ring
Working Condition: Low temperature organic tail gas, solvent recycling
Project Result:Polypropylene pall ring achieves stable mass transfer for organic vapor absorption. Recover valuable solvent to reduce raw material cost. PP material tolerates many weak organic solvents, no swelling deformation under normal temperature. Small size packing delivers high mass transfer efficiency for medium & small diameter columns.
