摘要： Apparatus is provided for use in carrying out liquid-liquid extraction techniques, which apparatus includes an extraction column containing a unique solvent sorbing packing material, namely a plurality or bundle of elongated fibrous strands having first and second end portions, the strands being capable of sorbing a desired solvent; the apparatus also includes a separation zone in communication with the second end of the plurality of fibrous strands, means for feeding a first or heavy solvent phase through the bundle of fibrous strands so as to be sorbed by said strands, and subsequently into the separation zone, means for feeding a second or light solvent phase into the separation zone and thence through the annular spaces of the column, around the fibrous strands contained therein, means for recovering the light solvent phase from the first end of said bundle and means for recovering said heavy solvent phase from said separation zone. Apparatus for separating two components by extraction techniques is also provided wherein the fibrous strand packing is utilized. A process is also provided for carrying out a continuous liquid-liquid countercurrent extraction employing two continuous phases. The process is carried out employing apparatus as described above.
