The Super mini ring Packing is primarily designed for liquid-liquid extraction processes. With an aspect ratio (height-to-diameter) ranging from 0.2 to 0.4, this packing eliminates the flanges of the stepped ring and incorporates inward-curved arc ribs to enhance structural strength. Its symmetrical and uniform design allows for orderly arrangement in random packing, resulting in a rational flow channel structure that effectively reduces axial backmixing within the packing layer. This contributes to improvements in both processing capacity and mass transfer performance.
