Abstract

AbstractRaschig Super‐Rings are well‐established in the field of rectification and absorption. Instead, the efficiency of these packings in liquid‐liquid extraction was not investigated till now. The application of Raschig Super‐Ring No. 0.3 and Raschig Super‐Ring No. 1 packings in unpulsed liquid‐liquid extraction columns of diameters DN 80 and DN 150 is investigated with respect to flooding point and efficiency. As a comparative study, 15‐mm and 25‐mm Pall‐Ring packings are used. The hydrodynamic studies indicate that the Raschig Super‐Ring offers a 9–10 % higher load capacity compared to the Pall‐Rings. In addition, the mass transport investigations performed using the test system toluene/acetone/water reveal that the height of transfer units (HTU) for the Raschig Super‐Ring No. 0.3 is higher than for the comparable 15‐mm Pall‐Ring. On average, the achieved difference of the HTU unit is 0.26 m.
