Applications
- Distillation Processes
Widely used in distillation towers across chemical, petrochemical, and pharmaceutical industries, it facilitates efficient separation of liquid mixtures. It is particularly effective in fractional distillation for refining solvents, hydrocarbons, and organic compounds, where precise component separation is critical.
- Absorption & Stripping Systems
Applied in absorption towers for gas purification (e.g., removing acid gases like SO₂ and CO₂ from industrial exhausts) and stripping towers for pollutant removal from wastewater. Its structured surface promotes thorough contact between gas and liquid phases, enhancing absorption efficiency.
- Solvent Recovery Units
In facilities recovering volatile solvents from industrial emissions or liquid streams, the packing supports effective mass transfer, enabling high recovery rates of valuable solvents such as alcohols, esters, and ketones, reducing waste and operational costs.

Advantages
- Enhanced Mass Transfer Efficiency: The unique inner arc design increases the effective surface area and promotes turbulent mixing of gas and liquid phases. This structure accelerates surface renewal of liquid films, boosting separation precision and reducing required tower height.
- Low Pressure Drop: Its optimized void fraction and smooth inner arc surface minimize resistance to fluid flow, reducing energy consumption for gas compression or liquid circulation compared to traditional packings like Raschig Rings.
- Stable Operational Performance: The robust geometric structure resists deformation under varying flow rates and temperatures, reducing the risk of channeling or flooding. This stability ensures consistent performance across a wide range of operating conditions.
- Broad Material Compatibility: Available in materials including ceramic, stainless steel, and plastic (PP, PVC), it adapts to corrosive, high-temperature, or high-pressure environments, suitable for handling acidic, alkaline, or neutral media.
