Abstract

1,223,903. Liquid/liquid extraction. KUHNI APPARATEBAU A.G. 21 March, 1968 [23 March, 1967], No. 13800/68. Headings BIC and B1F. A column for the counter-flow extraction of liquids, comprises exraction stages separated from each other by perforated separating plates, and impellers 2, rotatably mounted within each stage, in which each impeller has "non pitched" blades as defined below arranged so that the outer tips and the roots of each blade are angularly spaced from each other with respect to the axis of the impeller, and the plates are perforated within the region of each impeller. "Non-pitched" means that are blades extend between their top and bottom edges in a direction parallel to the axis of rotation of the impeller.
