METHOD AND DEVICE FOR CONTINUOUS COUNTERCURRENT TRANSFER OF MATERIAL BETWEEN TWO FLUID PHASES

摘要

Method for continuous exchange of material by countercurrent contacting of a first fluid phase and a second fluid phase that are not completely miscible, characterized in that the contacting is carried out in a single apparatus which is an apparatus of centrifugal partition chromatography (CPC) apparatus type into which only the first fluid phase and the second fluid phase are introduced, with the exclusion of any other phase, said apparatus comprising a plurality of cells, with a stationary phase immobilized in each of the cells and a mobile phase passing through the stationary phase, and in that the following steps a), b) and c) are carried out successively: a) step in which the mobile phase is formed by the first fluid phase, and the stationary phase immobilized in the cells is formed by the second fluid phase; b) step in which the mobile phase is formed by the second fluid phase, and the stationary phase immobilized in the cells is formed by the first fluid phase; c) repetition of the succession of steps a) and b); step b) being carried out immediately after step a) and step c) being carried out immediately after step b). Device for implementing this method.
