This packing features Conjugate Ring Packing with high symmetry, ensuring even stacking within the tower and preventing axial overlapping, thus achieving uniform distribution of liquid on the packing surface. Additionally, the numerous contact points between the internal ribs of adjacent packings and the packing surface, coupled with the significant average variation in surface curvature, facilitate liquid convergence and dispersion, promoting surface renewal of the liquid. These attributes contribute to the conjugate ring packing's advantages such as low pressure drop, uniform porosity, large gas-liquid contact surface area, and excellent hydrodynamic and mass transfer performance. Metal conjugate ring packing is particularly suitable for use in vacuum distillation towers, where it excels in handling heat-sensitive, easily decomposable, polymerizable, and carbon-forming materials. As a result, it is widely applied as packing in packed towers across various industries, including petrochemicals, fertilizers, and environmental protection.
