    Product Introduction

    Plastic pall ring is a high-performance random tower packing optimized based on traditional raschig ring, which is one of the most widely used mass transfer media in industrial separation towers. By redesigning the cylindrical wall structure, it overcomes the defects of poor gas-liquid circulation, high pressure drop and easy liquid channeling of raschig rings. This packing features excellent gas-liquid mixing performance, stable mass transfer efficiency and outstanding corrosion resistance, serving as a cost-effective solution for absorption, stripping, distillation, desulfurization, deaeration and waste gas treatment processes across chemical, environmental protection and petrochemical industries.
