| Abstract: | The hydrodynamics and mass transfer of Pulsed Packed Extraction Column (PPEC) havebeen studied using 30%TBP (kerosene)/HAc/H2O system. The effects of pulsation intensity and packingtype on PPEC were investigated. It is clear from the comparison that the characteristic of PPEC filledwith QH-1 has super characteristics than those of ceramic and stainless steel Raschig Rings. Empiricalequations of characteristic velocity and Hoxp for PPEC filled with QH-1 packing were proposed. |
