Multistage Cross-Current Extraction

Multistage cross-current extraction may be operated continuously or stagewise. In continuous cross-current extraction (Fig. 6-12), the mixture F to be separated is fed into the first stage where it is treated with the solvent Lj, From this extraction a raffinate and an extract E are obtained. [Pg.403]

If the distribution equilibrium between the raffinate and extract phase is reached, with continuous and stagewise extraction in each extraction stage, the compositions of the raffinate phases i ], R and ex- [Pg.404]
